Individuals desiring transportation (e.g., transportation by vehicle) between two locations can submit transportation requests to transportation providers. When fulfilling these transportation requests, transportation providers may predict routes associated with fulfilling the transportation request. For example, the transportation provider may predict a route followed by a vehicle when fulfilling the transportation request.
The present disclosure presents new and innovative systems and methods to detect and correct errors in predicted transportation routes. In one aspect, a method is provided comprising receiving, by a transportation matching system, a transportation request from a mobile device, wherein the transportation request includes at least two locations and generating, in response to the transportation request, a first route prediction, wherein the first route prediction is based on a first set of previously-completed routes associated with the at least two locations. The method may further include comparing the first route prediction with route information associated with a second set of previously-completed routes identified at least in part based on the first route prediction and identifying, based on the comparison, at least one route prediction error in the first route prediction. The method may also include generating, based on the at least one route prediction error, a second route prediction for the transportation request and sending, from the transportation matching system to the mobile device, the second route prediction.

The features and advantages described herein are not all-inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the figures and description. Moreover, it should be noted that the language used in the specification has been principally selected for readability and instructional purposes, and not to limit the scope of the disclosed subject matter.
Aspects of the present disclosure involve systems and methods for correcting errors (e.g., time and distance) in transportation route predictions that predict a time and distance required to travel a specific transportation route between two or more locations.
Various algorithms and processes currently exist for predicting a transportation route for a driver who intends to follow a specific path or route of travel between two locations, or multiple locations. For example, many transportation providers use route prediction algorithms and processes to provide route guidance to users. Transportation providers may include transportation networking companies (TNCs). TNCs may implement a transportation system that matches transportation requests with a dynamic transportation network of vehicles. The transportation system may communicate with computing devices associated with the vehicles in the network. In certain instances, the vehicles may include road-going vehicles and personal mobility vehicles. In some examples, some of the vehicles may be standard commercially available vehicles and some of the vehicles may be owned and/or operated by individuals. In some implementations, the vehicles may additionally or alternatively be autonomous (or partly autonomous). Accordingly, throughout the instant disclosure, references to a “vehicle operator” (or an “operator”) may, where appropriate, refer to a human driving a vehicle, an autonomous vehicle control system, an autonomous vehicle, an owner of an autonomous vehicle, an operator of an autonomous vehicle, an attendant of an autonomous vehicle, a requesting user piloting a vehicle, and/or an autonomous system for piloting a vehicle. In one example, the TNC may implement multiple transportation systems, where each transportation system is responsible for coordinating transportation matching for a region or set number of vehicles. In certain implementations, at least one of the transportation systems may allow users to select an individual vehicle for use. For example, a transportation system allocating personal mobility vehicles such as bikes or scooters may allow users to individually select the personal mobility vehicle they will use.
The transportation system may communicate with computing devices associated with the vehicles, which may be separate computing devices and/or may be integrated into the respective vehicles. In some examples, one or more of the computing devices may be mobile devices, such as a smart phone. Additionally or alternatively, one or more of the computing devices may be tablet computers, personal digital assistants, or any other type or form of mobile computing device. According to some examples, one or more of the computing devices may include wearable computing devices (e.g., a driver-wearable computing device), such as smart glasses, smart watches, etc. In some examples, one or more of the computing devices may be devices suitable for temporarily mounting in a vehicle (e.g., for use by a requestor and/or a transportation provider for a transportation matching application, a navigation application, and/or any other application suited for use by requestors and/or operators). Additionally or alternatively, one or more of the computing devices may be devices suitable for installing in a vehicle and/or may be a vehicle's computer that has a transportation management system application installed on the computer to provide transportation services to transportation requestors and/or communicate with the transportation system.
Additionally, the transportation matching system may communicate with user devices requesting transportation. In some examples, the user devices requesting transportation may include a requestor app implemented by the transportation provider. The requestor app may represent any application, program, and/or module that may provide one or more services related to requesting transportation services. For example, the requestor app may include a transportation matching application for requestors. In some examples, the requestor app may match the user of the requestor app (e.g., a transportation requestor) with transportation operators through communication with the transportation system. In addition, the requestor app may provide the transportation system with information about a requestor (including, e.g., the current location of the requestor) to enable the transportation system to provide dynamic transportation matching services for the requestor and one or more providers. In some examples, the requestor app may coordinate communications and/or a payment between a requestor and a provider. According to some embodiments, requestor app may provide a map service, a navigation service, a traffic notification service, and/or a geolocation service.
The transportation system may arrange transportation on an on-demand and/or ad-hoc basis by, e.g., matching one or more transportation requestors with one or more transportation providers. For example, a transportation matching system may provide one or more transportation matching services for a networked transportation service, a ridesourcing service, a taxicab service, a car-booking service, an autonomous vehicle service, a personal mobility vehicle service, or some combination and/or derivative thereof. The transportation system may include and/or interface with any of a variety of subsystems that may implement, support, and/or improve the transportation matching service. For example, the transportation matching system may include a matching system (e.g., that matches requestors to ride opportunities and/or that arranges for requestors and/or providers to meet), a mapping system, a routing system (e.g., to help a provider reach a requestor, to help a requestor reach a provider, and/or to help a provider reach a destination), a rating system (e.g., to rate and/or gauge the trustworthiness of a requestor and/or a provider), a payment system, and/or an autonomous or semi-autonomous driving system. The transportation matching system may be implemented on various platforms, including a requestor-owned mobile device, a computing system installed in a vehicle, a server computer system, or any other hardware platform capable of providing transportation matching services to one or more requestors and/or providers.
Turning now to the figures,
As shown in
As further shown in
As used in this disclosure, the term “GPS location” refers to data indicating a computing device's location using a Global Positioning System (or similar system, such as Global System for Mobile Communications). For example, a GPS location includes altitudinal, longitudinal, and/or latitudinal coordinates or degrees that the requestor client device 110 or the provider client device 116 sends to the server(s) 102 and the intelligent transportation routing system 104. In some instances, the intelligent transportation routing system 104 receives data from such a client device encoded to represent a GPS location in various standard GPS formats, such as degrees, minutes, and seconds (“DMS”); degrees and decimal minutes (“DMM”), or decimal degrees (“DD”).
As suggested above, GPS locations may indicate a route traveled by the requestor client device 110 or the provider client device 116. The term “route” refers to a course traveled from one location to another location. In particular, a route includes a course traveled by a client device from a starting location to a destination location. For example, a route may include a course traveled by the requestor client device 110 in the transportation vehicle 122 while the transportation vehicle 122 transports the requestor 114 from a pickup location to a destination location. As another example, a route may include a course traveled by the provider client device 116 in the transportation vehicle 122 after the provider 120 drops off the requestor 114 and travels to a different location.
As suggested above, the term “requestor” refers to a person who requests a ride or other form of transportation from the intelligent transportation routing system 104. A requestor may refer to a person who requests a ride or other form of transportation but who is still waiting for pickup. A requestor may also refer to a person whom a transportation vehicle has picked up and who is currently riding within the transportation vehicle to a destination (e.g., a destination indicated by a requestor).
Relatedly, the term “requestor client device” refers to a computing device associated with (or used by) a requestor. A requestor client device includes a mobile device, such as a laptop, smartphone, or tablet associated with a requestor. But the requestor client device 110 may also be any type of computing device as further explained below with reference to
A requestor may interact with a requestor application to request transportation services, receive a price estimate for the transportation service, and access other transportation-related services. For example, the requestor 114 may interact with the requestor client device 110 through graphical user interfaces of the requestor application 112 to input a pickup location or a destination location for transportation. The intelligent transportation routing system 104, via the server(s) 102, may in turn provide the requestor client device 110 with a price estimate for the transportation and an estimated time of arrival of the provider 120 (or the transportation vehicle 122) through the requestor application 112. Having received the price estimate and estimated time of arrival, the requestor 114 may then select (and the requestor client device 110 detect) a transportation-request option to request transportation services from the intelligent transportation routing system 104.
Relatedly, the term “provider” refers to a driver or other person who operates a transportation vehicle and/or who interacts with a provider client device. For instance, a provider includes a person who drives a transportation vehicle along various routes to pick up and drop off requestors. As shown in
As noted above, both the provider 120 and the transportation vehicle 122 are associated with the provider client device 116. The term “provider client device” refers to a computing device associated with a provider or a transportation vehicle. The provider client device 116 may be separate or integral to the transportation vehicle 122. For example, the provider client device 116 may refer to a separate mobile device, such as a laptop, smartphone, or tablet associated with the transportation vehicle 122. But the provider client device 116 may be any type of computing device as further explained below with reference to
Relatedly, the term “transportation vehicle” refers to a vehicle that transports one or more persons for an intelligent transportation routing system, such as an airplane, boat, automobile, motorcycle, or other vehicle. This disclosure primarily describes transportation vehicles as automobiles, such as cars, mopeds, shuttles, or sport utility vehicles, but the intelligent transportation routing system 104 may use any other transportation vehicle.
Although this disclosure often describes a transportation vehicle as performing certain functions, the transportation vehicle includes an associated provider client device that often performs a corresponding function. For example, when the intelligent transportation routing system 104 sends a transportation-request notification to the transportation vehicle 122— or queries location information from the transportation vehicle 122—the intelligent transportation routing system 104 sends the transportation-request notification or location query to the provider client device 116.
As further shown in
In some embodiments, the intelligent transportation routing system 104 communicates with the provider client device 116 through the provider application 118. In addition to those communications, the provider application 118 optionally includes computer-executable instructions that, when executed by the provider client device 116, cause the provider client device 116 to perform certain functions. For instance, the provider application 118 can cause the provider client device 116 to communicate with the intelligent transportation routing system 104 to send data representing GPS locations or receive a transportation-request notification or navigate to a pickup location to pick up a requestor.
As shown in
In addition to communicating with the provider client device 116 to receive GPS locations, the intelligent transportation routing system 104 optionally stores data corresponding to each route traveled and each transportation request on a transportation routing database 106 accessed by the server(s) 102. Accordingly, the server(s) 102 may generate, store, receive, and transmit various types of data, including, but not limited to, GPS locations, map-matched locations, location information, price estimates, estimated times of arrival, pickup locations, dropoff locations, and other data stored in the transportation routing database 106. In some such embodiments, the intelligent transportation routing system 104 organizes and stores such data in the transportation routing database 106 by geographic area, requestor, and/or time period.
Transportation providers may generate fixed fares upon receiving a transportation request from a requestor. For example, upon receiving a transportation request for transportation between two locations, the transportation provider may predict a fare for transportation between two locations. In particular, the predicted fare may be based on a predicted route between the two locations (e.g., based on a predicted time and/or distance to travel between the two locations). In addition, the predicted fare may be based on user preferences, such as user preferences for certain types of vehicles.
In some instances, the predicted route may include one or more inaccuracies. In particular, the initial route prediction may incorrectly estimate the route traveled, and therefore the distance, between the two locations specified in the transportation request. The predicted route may also inaccurately estimate the estimated time of arrival or departure for a vehicle servicing the route, which can alter the total amount of time necessary to fulfill transportation along the route. For example,
As another example, the initial route prediction may inaccurately estimate the actual distance traveled based on inaccurate pickup and/or drop off locations. For example,
Relatedly, the initial route prediction may be based on an inaccurate prediction of a transportation time for the transportation request. For example and with reference to
A transportation provider, such as a TNC, may be required to compensate a transportation provider for the time and distance required to pick up the requestor from location 132. Therefore, differences in the route and/or location to pick up a requestor may result in more or less time spent travelling to the requestor, which may change the actual route and cost for transportation between the locations 132, 134 and the ultimate accuracy of the initial route prediction, impacting any fixed fare generated by the TNC that were based on the route prediction
The time and distance inaccuracies of the routes used to generate the initial route prediction may therefore need to be corrected to properly provide upfront fares to requestors requesting transportation. Certain techniques may involve adjusting a fare multiplier based on previous prediction errors, but such techniques may not be able to accurately improve the upfront fares themselves, and further, lack transparency into the causes of the initial route prediction errors.
Thus, to solve these technical problems, among others, the disclosed system automatically analyzes generated route predictions for inaccuracies in the routes (e.g., time and distance inaccuracies). In particular, the initial route prediction can be compared to completed fares for similar transportation routes that were completed previously. Such a comparison may be performed by a predictive model to analyze how the initial route prediction for the similar transportation routes differ from actual route completed for the actual fare (i.e., the actual fare paid for by the transportation provider). Based on the comparison, a corrected route prediction can be generated for the requested transportation route. The corrected route prediction may identify how the initial route prediction was incorrect (e.g., may identify certain types of errors within the initial route prediction, such as time and distance errors).
The completed transportation route database 310 may contain information on previous transportation routes 312, 318. The previous transportation route 312 may include predicted and actual route information regarding the transportation route performed to fulfill a previously-received transportation request. In particular, and as illustrated in
The actual route information may include one or more of an actual starting location 470, an actual ending location 472, an actual travel time 474, an actual distance 475, and an actual route 476. The actual route information may reflect the actual route taken to fulfill the previously-received transportation request, including any changes to the predicted route 468 taken by a transportation provider, as well as any changes in starting and ending locations and the distance and travel time required to complete the transportation request. In certain implementations, after fulfilling the previously-received transportation request, the server 324 may store the predicted route information and the actual route information as the previous transportation route 312 in the completed transportation route database 310. Although not depicted, the previous transportation route 318 may include information and data similar to the information and data of the previous transportation route 312. The previous transportation routes 312, although not depicted, may also store information regarding the estimated time of arrival and/or departure along with the actual time of arrival or departure. These may be compared to estimated times of arrival and/or departure of the initial route prediction 330 and the corrected route prediction 336 to identify corresponding errors in each.
Referring again to
The initial route prediction process 326 may be configured to receive the starting location 306 and the ending location 308, specified in a transportation request 304, to generate an initial route prediction 330 between the starting location 306 and the ending location 308. For example and with reference to
To generate the initial route prediction 330, the predictive model 328 may process information indicative of routes traveled for transportation between the starting location 306 and the ending location 308. For example, the predictive model 328 may analyze previous transportation routes 312, 318 that are similar to the starting location 306 and/or ending location 308 used to generate the initial route prediction 330. The “similar” previous transportation routes 312, 318 (i.e., routes that are similar to the initial route prediction 330) may be identified by examining the actual route information stored by and/or within the previous transportation routes 312, 318. For example, the initial route prediction process 326 may identify previous transportation routes 312, 318, as being similar to the initial route prediction 330, because the previous transportation routes 312, 318 include actual starting locations 470 that are near the starting location 306 and/or actual ending locations 472 that are near the ending location 308. For example, a previous transportation route 312, 318 may be identified as similar if the actual starting location 470 is within a threshold distance of the starting location 306 of the transportation request 304. Similarly, a previous transportation route 312, 318 may be identified as similar if the actual ending location 472 is within a threshold distance of the ending location 308 of the transportation request 304. In certain implementations, the threshold distance may be, e.g., 10 feet, 100 feet, 1 block, or more. In still further implementations, the threshold distance may vary or dynamically updated based on the number of previous transportation routes 312 with actual starting locations 470 and/or actual ending locations 472 that are respectively near the starting location 306 and the ending location 308. For example, if there are a small number of such previous transportation routes 312, 318, the threshold distance may be set higher (e.g., so the initial route prediction process 326 has sufficient previous transportation routes 312, 318 for comparison). On the other hand, if there are many such previous transportation routes 312, 318, the threshold distance may be set lower (e.g., so the initial route prediction process relies only on the previous transportation routes 312, 318 that are most similar). In still further implementations, the predictive model 328 may be trained to identify which previous transportation routes 312, 318 qualify as sufficiently similar for generating the initial route prediction 330. Additionally, the previous transportation route 312, 318 may store indications of the starting and ending locations in an associated, previously-received transportation request. In such a scenario, the initial route prediction process 326 may identify previous transportation routes 312, 318 as “similar”, because the previous transportation routes 312, 318 share similar requested starting and ending locations (e.g., with “similar” determined with criteria analogous to those discussed above regarding the actual route information of the previous transportation routes 312, 318).
In performing the comparison, the initial route prediction process 326 may weight or otherwise combine information stored within the corresponding previous transportation routes 312, 318. For example, as depicted in
As shown in
The initial route prediction 330 may also include one or more of a predicted distance 416, a predicted travel time 418, and a predicted route 420. The predicted route 420 may represent the initial estimate (e.g., time and distance) for transportation between the starting location 412 and the ending location 414. The predicted route 420 may be stored as, e.g., coordinates indicating the path covered by a vehicle transporting a requestor along the predicted route 420. In certain implementations, the predicted distance 416 may be calculated based on the predicted route 420, e.g., by calculating a total distance covered by a vehicle transporting a requestor along the predicted route 420. Similarly, the predicted travel time 418 may be calculated based on the predicted route 420, e.g., an estimated amount of time for a vehicle to transport a requestor along the predicted route 420. In other implementations, the predicted travel time 418 may be calculated at least in part based on the similar previous transportation routes 312, 318 (e.g., based on the actual travel time 474).
In certain implementations, the initial route prediction 330 may be generated by a predictive model, such as the predictive model 328. For example, the predictive model 328 may be configured to identify and compare the similar previous transportation route 312, 318. In particular, the predictive model 328 may be trained to generate the initial route prediction 330 based on the received transportation request 304. For example, the predictive model 328 may be trained to generate the initial route prediction 330 by identifying previous transportation routes 312, 318 that are similar to the transportation request 304 (e.g., previous transportation routes 312, 318 that involve transportation between locations similar to the starting location 306 and/or ending location 308). In particular, the predictive model 328 may be trained on training data specifying (i) starting and ending locations 306, 308 for a particular previous transportation route 312, 318 and (ii) actual route information for the previous transportation route 312, 318. The predictive model 328 may be trained to generate initial route predictions 330 that are feasible, but these initial predictions may not always accurately represent, e.g., in distance or in time, the actual routes taken to fulfill transportation requests 304.
The inaccuracies of the initial route predictions 330 may result from the configuration of the prediction model 328. For example, the predictive model 328 may be configured to generate the initial route prediction 330 to meet a minimum accuracy threshold based on the previous transportation routes 312, 318 under certain performance constraints (e.g., time or computing resource constraints). Therefore, the initial route prediction 330 may be primarily generated to provide an initial estimate of the time and distance required for transportation from the starting location 306 to the ending location 308.
The route correction process 332 may therefore be configured to generate a corrected route prediction 336 based on the initial route prediction 330 and the transportation request 304. For example, the route correction process 332 may receive the initial route prediction 330 and the transportation request 304. The route correction process 332 may compare the initial route prediction 330 with previous transportation routes 312, 318 that are similar to the transportation request 304 to identify one or more errors in the initial route prediction 330. As discussed above, similar previous transportation routes 312, 318 may be identified from the completed transportation route database 310 based on an actual starting location 470 and/or an actual ending location 472 that are located near the starting location 306, 412 and/or the ending location 308, 414. However, the route correction process 332 may further identify previous transportation routes 312, 318 as being similar, if the previous transportation routes 312, 318 contain predicted route information that is similar to the initial route prediction 330 (e.g., where “similar” previous transportation routes 312, 318 are identified using criteria similar to those discussed above, but applied to predicted route information). In particular, the route correction process 332 may identify previous transportation routes 312, 318 with predicted starting locations 462 that are similar to the starting location 412 of the initial route prediction 330 and/or with predicted ending locations 464 that are similar to the ending location 414 of the initial route prediction 330.
Additionally or alternatively, similar previous transportation routes 312, 318 may be identified that have a predicted route 468, a predicted travel time 466, and/or a predicted distance 467, any one of which may be similar to the predicted route 468, the predicted travel time 418, and/or the predicted distance 416. In particular, the route correction process 332 may determine a level of similarity between the previous transportation routes 312, 318, and the initial route prediction, and may select the previous transportation routes 312, 318 with a similarity measure above a certain threshold as the similar previous transportation routes 312, 318. Relatedly, the route correction process 332 may select a certain number or certain proportion of the previous transportation routes 312, 318 (e.g., 100, 1,000, or more routes, or the most similar 1%, 5%, 10% of routes), and consider such selected routes as previous transportation routes that are similar to the initial route prediction. By incorporating the predicted route information when identifying similar previous transportation routes, the route correction process 332 may identify different routes than those utilized by the initial route prediction process (e.g., routes that were predicted to start near a location 132 but actually started near an alternative location 202A-C, or routes that were predicted to follow a certain route 136 but did not).
Once similar previous transportation routes 312 are identified, the route correction process 332 may compare the similar previous transportation routes 312, 318 to generate the corrected route prediction 336. For example, the route correction process 332 may perform the comparison to generate the corrected route prediction 336 by weighting or otherwise combining information from the previous transportation routes 312, 318 that most closely resemble the initial route prediction 330. For example, the route correction process 332 may combine information regarding the actual route 476, the actual distance 475, the actual travel time 474, the actual ending time 472, and the actual starting location 470 from the similar previous transportation routes 312, 318 to generate the corrected route prediction 336. In particular, the route correction process 332 may give a higher weight the actual information from previous transportation routes 312, 318 with one or more similar pieces of predicted route information 462, 464, 466, 467, 468 with the initial route prediction 330.
The corrected route prediction 336 may be generated to include one or more corrected pieces of information from the initial route prediction 330. For example, as depicted in
In some instances, the route correction process 332 may also generate a corrected route 440, where a change in route 136 to an alternative route 138A-C is likely based on the similar previous transportation routes 312, 318. Furthermore, based on any of the above changes and/or after determining, based on the similar previous transportation routes 312, 318, that road conditions or other circumstances are likely to result in a change in travel time from the predicted travel time 418, the route correction process 332 may generate a corrected travel time 438. Depending on the accuracy of the initial route prediction 330, the corrected route prediction 336 may only include one or a subset of corrected pieces of information 432, 434, 436, 438, 440. In particular, if one or more pieces of information contained within the initial route prediction 330 are determined (e.g., based on the similar previous transportation routes 312, 318) to be correct, the correct information may be included in its original form within the corrected route prediction 336. For example, both the starting and ending locations 412, 414 may be correct, but the route taken between the starting and ending locations 412, 414 may differ. In such an instance, the starting and ending locations 412, 414 may be included within the corrected route prediction 336, while the corrected route 440 indicates the more likely route, along with the appropriate corrected distance 436 and corrected travel time 438 as needed based on the corrected route 440.
In certain implementations, the corrected route prediction 336 may be generated by a predictive model, such as the predicted model 334. For example, the predictive model 334 may be trained to identify, based on predicted route information, similar previous transportation routes 312, 318 within the completed transportation route database 310 and/or to analyze the previous transportation routes 312, 318 according to one or more of the techniques discussed above. In particular, the predictive model 334 may be trained to perform one or more of the operations discussed on all or a subset of the data within the completed transportation route database 310.
For example, the predictive model 334 may be trained by receiving: 1) one or more pieces of predicted route information corresponding to the types of information included in the initial route prediction 330; and 2) actual route information corresponding to actual routes taken for previously-predicted trips. In particular, the predicted starting location 462 may correspond to a starting location 412 generated by the initial route prediction process 326 and the predicted ending location 464 may correspond to an ending location 414 generated by the initial route prediction process 326. Similarly, the predicted travel time 466, the predicted distance 467, and the predicted route 468 may correspond to the predicted distance 416, the predicted travel time 41A, and the predicted route 420 from an initial route prediction 330 generated for a previously-completed transportation request. The predicted route information may be compared to the actual route information 470, 472, 474, 475, 476 during training to identify how initial route predictions 330 generated by the initial route prediction process 326 typically differ from the actual routes taken. The predictive model 334 may then be trained to generate the corrected route prediction 336 to correct these errors and thereby generate a prediction that more closely corresponds to the actual transportation route taken to fulfill the previous transportation requests. Furthermore, the predictive model 334 may be trained to incorporate additional types of information, such as the time of day or week at which a transportation request 304 is received, current weather conditions, current traffic conditions, current nearby events, and/or current overall marketplace conditions nearby on a transportation platform provided by the transportation provider (e.g., ridership levels as compared to current capacity for nearby vehicles).
The corrected route prediction 336 may also be generated to specify one or more types of errors in the initial route prediction 330. In particular, the corrected route prediction 336 may include one or more of a pickup time error 442, a travel time error 444, a pickup distance error 446, and a travel distance error 448. The pickup distance error 446 may be generated when the starting location 412 generated by the initial route prediction process 326 differs from the corrected starting location 432. The locations 412, 432 may differ by a certain distance, which may be specified by the pickup distance error. The pickup time error 442 may be calculated in similar situations and may reflect the difference in time required to pick up a requestor given the difference between the corrected starting location 432 and the starting location 412, as in the scenario 200. The travel distance error 448 may be generated when the corrected distance 436 differs from the predicted distance 416 (e.g., because the corrected route 440 differs from the predicted route 420). The travel distance error 448 may indicate an amount by which the distances 416, 436 differ. The travel time error 444 may be generated when the corrected travel time 438 differs from the predicted travel time 318 (e.g., because the corrected route 440 differs from the predicted route 420, because traffic or other road conditions alter the expected travel time along the predicted route). In certain implementations, the route correction process 332 may calculate the errors 442, 444, 446, 448 based on the one or more pieces of corrected information 432, 434, 436, 438, 440. For example, the predictive model 334 may be trained to generate the corrected information 432, 434, 436, 438, 440, which are then utilized by the route correction process 332 (e.g., heuristics included within the route correction process 332) to generate the errors 442, 444, 446, 448.
In other implementations, the predictive model 334 may directly predict the errors 442, 444, 446, 448 based on the initial route prediction 330 and the transportation request 304. For example, the predictive model 334 may be trained to predict the corrected information 432, 434, 436, 438, 440 and the errors 442, 444, 446, 448 during the same process. In still further implementations, the predictive model 334 may not directly determine the corrected information 432, 434, 436, 438, 440 and may instead only be trained to predict the errors 442, 444, 446, 448. In such implementations, the corrected information 432, 434, 436, 438, 440 may not be included in the corrected route prediction 336.
Although the initial route prediction process 326 and the route correction process 332 may each be implemented at least in part by predictive models 328, 334, these predictive model 328, 334 may be configured differently. For example, the predictive model 328 may be trained to make a different prediction from the predictive model 334. In particular, the predictive model 328 may be configured to generate an initial, feasible prediction of a route 136 connecting the starting location 306 to the ending location 308, along with associated time and distance estimates. Further, to reduce processing time, data inputs to the predictive model 328 may be comparatively limited (e.g., the predictive model 328 may only consider the transportation request 304 and previous transportation routes 312, 318).
However, because the predictive model 334 receives the initial route prediction 330, the predictive model 334 may instead be directed to refining and correcting the initial route 136 predicted by the predictive model 328. Because of this, the predictive model 334 may consider additional data inputs from those available to the predictive model 328 (e.g., the predicted route information from the previous transportation routes 312, 318, weather information, traffic and road conditions) without suffering unacceptable performance delays. Furthermore, because the route correction process 332 is configured to incorporate predicted route information stored in the previous transportation routes 312, 318, the predictive model 334 may be separately trained to incorporate and adjust for idiosyncrasies of the predictive model 328. For example, the predictive model 328 may regularly make certain types of mistakes (e.g., in placing the starting location 412 in the ending location 414, or failing to account for differences in travel time in certain areas due to traffic and other road conditions). Because the predictive model 334 may be trained to incorporate the specifics of the initial route prediction 330 and previous predicted route information generated by the initial route prediction process 326, the predictive model 334 may resolve these systemic inaccuracies without having to resort to more complex models or prediction processes.
Such a two-tiered approach to route prediction may both reduce the computing resources required and also reduce processing time, thereby increasing accuracy while also enabling timely responses to transportation requests 304. For example, in certain implementations, if a single predictive model were configured to incorporate the data inputs of both the predictive model 328 and the predictive model 334, the predictive model may be too resource intensive to generate route predictions in time to present the upfront fare 340 to the user device 302. Therefore, by utilizing two predictive models 328, 334 to first generate an initial route prediction 330 and then refine and correct that prediction to generate a corrected route prediction 336, the server 324 may be able to receive and process transportation requests 304 with more accurate route predictions without utilizing excessive computing resources or sacrificing system responsiveness for the system 300.
In certain implementations, the predictive models 328, 334 may be implemented as one or more machine learning models, including supervised learning models, unsupervised learning models, and other types of machine learning models. For example, the predictive models 328, 334 may each be implemented as one or more of a regression model, a neural network, a decision tree model, a support vector machine, and a Bayesian network. In certain implementations, the predictive model 328 and the predictive model 334 may be implemented as different types of machine learning models. However, in other implementations, the predictive models 328, 334 may both be implemented as regression models.
The upfront fare adjustment process 338 may receive the corrected route prediction 336 and may generate an upfront fare 340 for presentation to the user device 302. For example, as shown in
One or more of the user device 302, the completed transportation route database 310, and the server 324 may be implemented by a computing system. For example, although not depicted, one or more of the user device 302, the completed transportation route database 310, and the server 324 may include a processor and a memory that implement at least one operational feature. For example, the memory may contain instructions which, when executed by the processor, cause the processor to implement at least one operational feature of the user device 302, the completed transportation route database 310, and/or the server 324.
It should also be appreciated that, although embodiments of the previous transportation routes 312, the initial route prediction 330, the corrected route prediction 336, and the upfront fare 340 depicted in
The method 500 may begin with the server 324 receiving a transportation request 304 (block 502). The transportation request 304 may be received from a requestor and may request transportation from a starting location 306 to an ending location 308. The server 324 may then generate an initial route prediction 330 for fulfilling the transportation request 304 (block 504). For example, the initial route prediction process 326 may generate an initial route prediction 330 including a predicted route 420 between the starting location 306 to the ending location 308. As explained above, the initial route prediction 330 may be generated at least in part using a predictive model 328 and may include one or more route inaccuracies (e.g., time and or distance inaccuracies). In certain implementations, block 502 may be optional. For example, rather than receiving the transportation request 304 at block 502 and generating the initial route prediction 330 at the server, block 504 may be performed at least in part by a mobile device associated with the requestor.
The server 324 may then receive the initial route prediction 330 (block 506). For example, the route correction process 332 may receive the initial route prediction 330 from the initial route prediction process 326 for correction. The route correction process 332 may then compare the initial route prediction to similar previous transportation routes 312, 318 (block 508). For example, the route correction process 332 may compare predicted route information 412, 414, 416, 418, 420 from the initial route prediction 330 with information from the similar previous transportation routes 312 (e.g., a second set of similar previous transportation routes 312 at least partially different from the previous transportation routes 312 used to generate the initial route prediction 330). In particular, the similar previous transportation routes 312, 318 may be identified by comparing the predicted route information 412, 414, 416, 418, 420 from the initial route prediction 330 with predicted route information 462, 464, 466, 467, 468 from the previous transportation route 312. The route correction process 332 may then identify one or more errors in the initial route prediction 330 requiring correction. For example, one or more of the starting location 412, the ending location 414, the predicted distance 416, the predicted travel time 418, and the predicted route 420 may be incorrect based on the comparison to the similar previous transportation routes 312, 318.
The server 324 may therefore generate a corrected route prediction 336 (block 510). For example, for each of the errors identified at block 508, the route correction process 332 may generate corrected information 432, 434, 436, 438, 4404 inclusion within the corrected route prediction 336. Additionally or alternatively, the route correction process 332 may generate one or more of a pickup time error 442, a travel time error 444, a pickup distance error 446, and a travel distance error 448 identifying corresponding errors in the initial route prediction 330, as discussed above. In certain implementations, the corrected route prediction 336 may also include an amount of error for each type of error 442, 444, 446, 448. As discussed above, one or both of blocks 508, 510 may be implemented by the predictive model 334, which may be trained to identify and correct common errors within the predictive model 328. Further, the predictive model 334 may be trained to consider additional types of information, such as weather conditions along the predicted route 420 and/or the corrected route 440, a time of the day or week at which the transportation request 304 is to be fulfilled, and/or traffic and road conditions along the predicted route 420 and/or the corrected route 440. Accordingly, the corrected route prediction 336 may represent a more accurate estimation of the transportation route required to fulfill the transportation request 304.
In certain implementations, the corrected route prediction 336 may then be processed by the upfront fare adjustment process 338 to generate an upfront fare 340 for presentation to the user device 302 in response to the received transportation request 304. Based on the upfront fare 340, a requestor associated with the user device 302 may then accept or deny transportation services from the transportation provider implement in the server 324. In still further implementations, the corrected route prediction 336 may not be used to generate the upfront fare 340, but may instead be used to further train or refine the predictive model 334, as discussed further below.
The method 600 may begin with receiving actual route information corresponding to the transportation route after completion (block 602). For example, after generating the corrected route prediction 336, a requestor may accept the upfront fare 340 presented in response to the transportation request 304. The transportation provider may then proceed with fulfilling the transportation request (e.g., by transporting the requestor using one or more vehicles such as cars, scooters, and bicycles). During fulfillment of the transportation request, the server 324 may collect actual route information regarding the transportation route taken. For example, the server 324 may collect one or more of an actual starting location 470, an actual ending location 472, an actual travel time 474, an actual distance 475, and an actual route 476, similar to those above in connection with the previous transportation route 312.
The server 324 may then determine errors between the corrected route prediction 336 and the actual route information 470, 472, 474, 475, 476 (block 604). For example, the server 324 may identify one or more discrepancies between items of the corrected route information 432, 434, 436, 438, 440 and the corresponding pieces of actual route information 470, 472, 474, 475, 476. These differences may be identified as errors for training purposes. Based on these errors, the predictive model 334 may be updated (block 606). For example, during a training procedure of the predictive model 334, the corrected information 432, 434, 436, 438, 440 and the actual route information 470, 472, 474, 475, 476 may be provided along with the identified errors. The predictive model 334 may then be updated during the training process (e.g., by adjusting one or more weights, inputs, or other configuration settings of the predictive model 334).
By performing the method 600, the predictive model 334 may be self-correcting and may improve in accuracy over time. For example, performing the method 600 may enable the predictive model 334 to identify and learn from previous mistakes by adjusting the configurations of the predictive model 334 to account for these mistakes. Similarly, in certain implementations, the method 600 may be used to initially train the predictive model 334. For example, where the absolute accuracy of the predictive model 334 may be in doubt, the method 500 may be performed to generate a corrected route prediction 336 for incoming transportation requests 304, but the corrected route prediction 336 may not be used for generation of the upfront fare 340. Rather, the corrected route prediction 336 may be stored and subsequently compared with actual route information collected during fulfillment of the received transportation requests 304 for training purposes according to the method 600. This process may be repeated until the predictive model 334 is trained sufficiently to generate corrected route predictions 336 accurate enough to form the basis for an upfront fare 340.
In still further implementations, the corrected route prediction 336 may similarly be used to train the predictive model 328. For example, after the corrected route prediction 336 is generated, the corrected route prediction 336 may be provided to the predictive model 328, which may compare the corrected route prediction 336 to the initial route prediction 330 and identify one or more errors in the initial route prediction 330 based on the corrected route prediction 336. The predictive model 328 may then be updated to account for the identified errors, similar to updating the predictive model 334 at block 606.
Embodiments of the present disclosure may comprise or utilize a special purpose or general-purpose computer including computer hardware, such as, for example, one or more processors and system memories, as discussed in greater detail below. Embodiments within the scope of the present disclosure also include physical and other computer-readable media for carrying or storing computer-executable instructions and/or data structures. In particular, one or more of the processes described herein may be implemented at least in part as instructions embodied in a non-transitory computer-readable medium and executable by one or more computing devices (e.g., any of the media content access devices described herein). In general, a processor (e.g., a microprocessor) receives instructions, from a non-transitory computer-readable medium, (e.g., a memory, etc.), and executes those instructions, thereby performing one or more processes, including one or more of the processes described herein.
Computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer system, including by one or more servers. Computer-readable media that store computer-executable instructions are non-transitory computer-readable storage media (devices). Computer-readable media that carry computer-executable instructions are transmission media. Thus, by way of example, and not limitation, embodiments of the disclosure can comprise at least two distinctly different kinds of computer-readable media: non-transitory computer-readable storage media (devices) and transmission media.
Non-transitory computer-readable storage media (devices) includes RAM, ROM, EEPROM, CD-ROM, solid state drives (“SSDs”) (e.g., based on RAM), Flash memory, phase-change memory (“PCM”), other types of memory, other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer.
Further, upon reaching various computer system components, program code means in the form of computer-executable instructions or data structures can be transferred automatically from transmission media to non-transitory computer-readable storage media (devices) (or vice versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computer system RANI and/or to less volatile computer storage media (devices) at a computer system. Thus, it should be understood that non-transitory computer-readable storage media (devices) can be included in computer system components that also (or even primarily) utilize transmission media.
Computer-executable instructions comprise, for example, instructions and data which, when executed at a processor, cause a general-purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions. In some embodiments, computer-executable instructions are executed on a general-purpose computer to turn the general-purpose computer into a special purpose computer implementing elements of the disclosure. The computer executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code. Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims.
Those skilled in the art will appreciate that the disclosure may be practiced in network computing environments with many types of computer system configurations, including, virtual reality devices, personal computers, desktop computers, laptop computers, message processors, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, mobile telephones, PDAs, tablets, pagers, routers, switches, and the like. The disclosure may also be practiced in distributed system environments where local and remote computer systems, which are linked (either by hardwired data links, wireless data links, or by a combination of hardwired and wireless data links) through a network, both perform tasks. In a distributed system environment, program modules may be located in both local and remote memory storage devices.
Embodiments of the present disclosure can also be implemented in cloud computing environments. In this description, “cloud computing” is defined as a model for enabling on-demand network access to a shared pool of configurable computing resources. For example, cloud computing can be employed in the marketplace to offer ubiquitous and convenient on-demand access to the shared pool of configurable computing resources. The shared pool of configurable computing resources can be rapidly provisioned via virtualization and released with low management effort or service provider interaction, and then scaled accordingly.
A cloud-computing model can be composed of various characteristics such as, for example, on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service, and so forth. A cloud-computing model can also expose various service models, such as, for example, Software as a Service (“SaaS”), Platform as a Service (“PaaS”), and Infrastructure as a Service (“IaaS”). A cloud-computing model can also be deployed using different deployment models such as private cloud, community cloud, public cloud, hybrid cloud, and so forth. In this description and in the claims, a “cloud-computing environment” is an environment in which cloud computing is employed.

As noted above, the intelligent transportation routing system 104 trains an artificial network. In some such embodiments, generating the trained artificial neural network comprises generating a training route tile for a training region along a training route based on training GPS locations and corresponding training map-matched locations; utilizing an artificial neural network to predict a route-accuracy metric for the training region based on the training route tile; and generating the trained artificial neural network by comparing the route-accuracy metric to a ground-truth-route-accuracy metric for the training region.
Relatedly, in some implementations, generating the simulated training GPS locations comprises creating simulated route locations for the training route within a road network based on standard-traveling patterns of transportation vehicles; and generating the simulated training GPS locations by transforming the simulated route locations based on a GPS-noise model.

Additionally, in certain embodiments, the acts 700 include generating regions along the route. For instance, in certain embodiments, the acts 700 include generating a plurality of regions along the route, wherein a region comprises a subset of GPS locations and a subset of map-matched locations.
Moreover, in some implementations, the acts 700 include generating a route tile for the region. For example, in some implementations, the act 700 includes generating a route tile for the region based on the subset of GPS locations and the subset of map-matched locations.
Further, in certain implementations, the acts 700 include utilizing an artificial neural network to determine a route-accuracy metric for the region. For instance, in some embodiments, the acts 700 includes utilizing an artificial neural network to determine a route-accuracy metric for the region based on the route tile. In certain embodiments, the route-accuracy metric for the region comprises an accuracy classifier for the route tile indicating a level of noise of the subset of GPS locations.
Finally, in some such embodiments, the acts 700 include determining a distance of the route based on the route-accuracy metric. As noted above, the route-accuracy metric may take a variety of forms. For example, in some embodiments, the route-accuracy metric comprises a classifier indicating the subset of GPS locations; and determining the distance of the route based on the route-accuracy metric comprises determining a regional distance traveled by the client device within the region based on the subset of GPS locations. In some such embodiments, the acts 700 further include, based on the classifier indicating the subset of GPS locations, adjusting a digital map for the region to correspond to the subset of GPS locations.
Alternatively, in some embodiments, the route-accuracy metric comprises a classifier indicating the subset of map-matched locations; and determining the distance of the route based on the route-accuracy metric comprises determining a regional distance traveled by the client device within the region based on the subset of map-matched locations.
Additionally, in certain embodiments, the route-accuracy metric for the region comprises a regional distance traveled by the client device within the region based on the route tile; and determining the distance of the route based on the route-accuracy metric comprises determining the distance of the route based on the regional distance traveled by the client device within the region.
As suggested above, in some embodiments, the acts 700 further include utilizing the artificial neural network to determine an additional route-accuracy metric for an additional region based on an additional a route tile; and determining the distance of the route based on the additional route-accuracy metric for the additional region and the route-accuracy metric for the region.
In particular embodiments, processor(s) 802 includes hardware for executing instructions, such as those making up a computer program. As an example, and not by way of limitation, to execute instructions, processor(s) 802 may retrieve (or fetch) the instructions from an internal register, an internal cache, memory 804, or a storage device 806 and decode and execute them.
