Some transportation services may provide transportation on demand, drawing from a transportation provider supply pool to meet the needs of those requesting transportation services as the needs arise. A transportation provider supply pool may include the use of personal mobility vehicles to fulfill transportation requests from transportation requestors. However, the use of personal mobility vehicles by transportation requestors may subject the transportation requestors and others in proximity to safety concerns. Safety concerns may arise for transportation requestors and others in proximity to transportation requestors operating personal mobility vehicles when the personal mobility vehicles or vehicles in proximity to the personal mobility vehicles are operated in an unsafe fashion.
Accordingly, operation of personal mobility vehicles by transportation requestors may pose safety concerns to transportation requestors, personal mobility vehicles, pedestrians, vehicles and vehicle operators.
The accompanying drawings illustrate a number of example embodiments and are a part of the specification. Together with the following description, these drawings demonstrate and explain various principles of the instant disclosure.
Throughout the drawings, identical reference characters and descriptions indicate similar, but not necessarily identical, elements. While the example embodiments described herein are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, the example embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the instant disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.
The present disclosure is generally directed to increasing safety in operating personal mobility vehicles, methods and systems for controlling, using, tracking, and/or interacting with personal mobility vehicles, and methods and systems for integrating personal mobility vehicles within dynamic transportation networks. The present disclosure describes methods of increasing safety related to PMV operation by taking advantage of the various sources and types of information related to PMV operation that are available in the dynamic transportation network. Limiting the performance of the PMV operation may help improve the experience and safety of the transportation requestor operating the PMV based on their level of experience.
The present method may provide various benefits to the transportation requestor operating a PMV which include, without limitation, increasing the safety of the transportation requestor and others in proximity to the transportation requestor operating the PMV. The present method may provide further benefits to the transportation requestor by increasing the efficiency of the transportation (e.g., providing an efficient travel route, ensuring arrival at a destination before power depletion of the PMV, etc.), and increasing the comfort of the transportation requestor during operation (e.g., directing the transportation requestor to bike lanes, directing the transportation requestor away from uncomfortable terrains and/or high traffic density routes, etc.).
The present method may provide various benefits to the dynamic transportation network which include, without limitation, increasing the efficiency of the dynamic transportation network, and increasing the satisfaction of the transportation requestor with the transportation service.
Accordingly, as may be appreciated, the systems and methods described herein may improve the functioning of a computer that implements methods of increasing safety in PMV operation. For example, these systems and methods may improve the functioning of the computer by improving dynamic transportation efficiency. Additionally or alternatively, these systems and methods may improve the functioning of the computer by reducing the computing resources consumed to identify usage information relating to the operation of a PMV (and, e.g., thereby freeing computing resources for other tasks, such as those directly and/or indirectly involved in dynamic transportation matching). In some examples, these systems and methods may improve the functioning of a computer controlling a PMV by using information gathered from the dynamic transportation network to control a transportation function in the PMV.
A dynamic transportation matching 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 dynamic transportation matching system may match a transportation requestor to a transportation provider that operates within a dynamic transportation network (e.g., that is managed by, coordinated by, and/or drawn from by the dynamic transportation matching system to provide transportation to transportation requestors).
In some examples, available sources of transportation within a dynamic transportation network may include vehicles that are owned by an owner and/or operator of the dynamic transportation matching system. Additionally or alternatively, sources of transportation within a dynamic transportation network may include vehicles that are owned outside of the dynamic transportation network but that participate within the dynamic transportation network by agreement. In some examples, the dynamic transportation network may include road-going vehicles (e.g., cars, light trucks, etc.). Furthermore, in some examples, as will be explained in greater detail below, the dynamic transportation network may include personal mobility vehicles.
As used herein, the term “personal mobility vehicle” (or “PMV”) may refer to any of a variety of types of vehicles that may be smaller and/or lighter than traditional road-going vehicles. In some examples, a personal mobility vehicle may have fewer than four wheels. In some examples, personal mobility vehicles may be more flexible, maneuverable, and may be provided access to particular portions of a road way (e.g., bike lane, sidewalk, etc.) that traditional automobiles may not legally be able to access. Personal mobility vehicles may be human and/or motor powered and may have any suitable sized and/or powered motor to allow the personal mobility vehicle to travel any suitable speed and carry any suitable load. In some embodiments, without limitation, a personal mobility vehicle may operate with less than about five horsepower, less than about four horsepower, or less than about three horsepower. Notwithstanding the above examples, PMVs may operate at any suitable horsepower level (e.g., significantly higher horsepower levels). In various examples, without limitation, a personal mobility vehicle may weigh less than about 150 pounds, less than about 100 pounds, less than about 70 pounds, or less than about 50 pounds. Notwithstanding the above examples, PMVs may have any suitable weight. In various examples, without limitation, a personal mobility vehicle may operate at a maximum speed (e.g., absent downhill acceleration) of about 35 miles per hour or less, about 30 miles per hour or less, about 25 miles per hour or less, or about 20 miles per hour or less. Nothwithstanding the above examples, PMVs may operate at any suitable speed (including, e.g., significantly higher speeds. In some examples, a personal mobility vehicle may be designed to transport a single passenger. However, in some embodiments, the personal mobility vehicles may also transport more than a single passenger (e.g., a tandem bicycle). In some examples, a personal mobility vehicle may be partially or fully self-powered (e.g., through a combustion motor or an electric motor). In some examples, a personal mobility vehicle may be partially or fully human-powered. Examples of personal mobility vehicles include, without limitation, scooters, unicycles, electric wheelchairs, powered bicycles, powered tricycles, human transporters, powered skateboards, pedaled bicycles, and electric bicycles. In some examples, a personal mobility vehicle may be maneuverable in a variety of situations (e.g., on a street, on a sidewalk, in a bike lane, etc.), may be light-weight relative to road-constrained vehicles, may be portable (e.g., capable of being picked up and moved by a single person without power assistance), may be lockable (e.g., in place and/or to a docking system) and/or may be adapted to be stored and/or locked outdoors (e.g., on a sidewalk) and/or in a docking system.
In some examples, a dynamic transportation matching system may match transportation requestors to personal mobility vehicles. For example, the dynamic transportation matching system may determine that a starting location of a transportation requestor is near an available personal mobility vehicle within the dynamic transportation network; provide, to the transportation requestor, directions to the personal mobility vehicle; and transmit instructions to the personal mobility vehicle to unlock and/or activate for the transportation requestor. The transportation requestor may then ride the personal mobility vehicle to a destination.
A wide variety of people having different levels of experience, skill, and physical attributes (e.g., age, weight, strength, etc.) may use PMVs in various operating environments. To accommodate people of different skill levels, ages, and behavioral profiles, systems described herein may modify the functionality of a PMV based on user characteristics and/or the context (e.g., geolocation) of the use. Thus, systems described herein may improve user experience and user safety while preserving PMV functionality.
In some examples, systems described herein may limit the speed of a PMV based at least in part on the detected terrain of the PMV. For example, the PMV may include one or more sensors (e.g., inertial measurement units, accelerometers, gyroscopes, etc.) that provide information for determining the speed, acceleration, position and/or orientation of the PMV (or of various components of the PMV) and may, based on data from the sensors, determine an incline of the terrain on which the PMV is traveling. Thus, for example, systems described herein may limit the speed of a PMV on a downhill incline (and, in some examples, on a flat incline). In some examples, systems described herein may determine whether the PMV is operating on a sidewalk to make a safety determination and/or perform a safety action. For example, systems described herein may use sensor information (e.g., accelerometer information, gyroscope, camera images, etc.) to determine the surface material on which the PMV is traveling is sidewalk material (e.g., concrete). Additionally or alternatively, systems described herein may use sensor information (e.g., accelerometer) to determine that the PMV has jumped a curb onto (or off from) a sidewalk. In response to determining that a transportation requestor is unsafely operating a PMV on a sidewalk (e.g., based on determining that the PMV is restricted from traveling on sidewalks and/or that the PMV has exceeded safe sidewalk speeds), systems described herein may modify at least one transportation function of the PMV. Examples of modifying a transportation function of a PMV include, without limitation, reducing the maximum speed of the PMV, providing feedback to the transportation requestor (e.g., in real time and/or after the trip has completed), disqualifying the requestor from future PMV use, etc. Real-time feedback to the requestor may include any of a variety of feedback methods, including, without limitation, haptic feedback (e.g., provided via the PMV), audio feedback (e.g., a warning buzzer, audible instructions, etc.) and visual feedback (e.g., warning lights on the PMV, a display device on the PMV, a heads up display, a head-mounted display, etc.).
In some examples, systems described herein may evaluate the ability of a transportation requestor to operate a PMV. For example, these systems may calculate an ability score based on any of a variety of factors, including, without limitation, the number of PMV rides (e.g., within a dynamic transportation network) taken by the transportation requestor, the number of successful (e.g., evaluated to be safe) rides taken by the transportation requestor, the monitored behavior of the user on the vehicle, the amount of time spent by the transportation requestor operating PMVs, the number and/or recency of PMV function modifications taken in response to the transportation requestor's operation of PMVs, etc. In some examples, these systems may additionally or alternatively use user-supplied information to evaluate the ability of the transportation requestor. For example, the transportation requestor may provide information about experience and/or comfort level with operating the PMV, and/or physical attributes (e.g., age weight, height, etc.) of the transportation requestor. According to some examples, systems described herein may restrict and/or unlock capabilities of the PMV based on the evaluated ability of the requestor. For example, systems described herein may unlock higher maximum speeds for the PMV based on determining that the ability score of the requestor exceeds a predetermined threshold.
In some examples, systems described herein may use geofences to apply safety controls to a PMV. For example, systems described herein may restrict use of a PMV outside of a geofenced area (e.g., based on determining that operation of the PMV outside the geofenced area is unsafe or otherwise not allowed). For example, systems described herein may identify streets designated as safe for PMV travel and/or streets designated as unsafe for PMV travel (or not designated as safe for PMV travel) and restrict use of the PMV on streets designated as unsafe. Additionally, the skill level of the transportation requestor and/or matched operator of the PMV may dictate which routes are authorized/safe for the user vs. unsafe/unauthorized for the user. For example, beginning users may only be authorized for travel on roads with clear bike paths and/or separated medians from vehicular traffic while more advanced users may be allowed access to roads that do not have designated bike paths, segments of roads outside a bike path, and/or uphill/downhill roads, etc. In some examples, systems described herein may activate a lock on the PMV, notify a user of the safety concern, and/or reduce or deactivate power to the PMV based on determining that the PMV is entering an unsafe or unauthorized area.
In some examples, systems described herein may enable parents to configure safety settings for children. For example, when a child requestor uses a PMV within a dynamic transportation network, a dynamic transportation management system may look up safety settings for the child requestor and apply the safety settings and/or transmit the safety settings to the PMV. Examples of safety settings include, without limitation, restricting areas of travel, providing parental notifications of areas of travel, safety violations, and/or accidents, and/or setting the maximum speed of the PMV.
In some examples, systems described herein may sense a requestor's state (e.g., in proper position to operate the PMV vs. not in proper position to operate the PMV; focused on operating the PMV vs. not focused on operating the PMV, etc.) to determine appropriate PMV function modifications. For example, systems described herein may sense whether both of a requestor's hands are on the handlebars of a PMV (and perform a PMV function modifications otherwise). In another example, systems described herein may pair with a requestor's mobile device and determine whether the mobile device is active (e.g., in a call), being operated during a ride, or if the mobile device otherwise indicates that a rider may be interacting with the mobile device instead of focusing on the road or operation of the PMV. Similarly, in these examples, systems described herein may perform a PMV function modification (e.g., lower the maximum speed of the PMV, lower the current speed of the PMV, apply a braking system of the PMV, send a message to the transportation requestor's mobile device, lock the PMV, and/or otherwise indicate the safety concern) if the transportation requestor is actively using the mobile device.
In some examples, systems described herein may verify that a transportation requestor is wearing safety equipment (e.g., a helmet) before activating and/or unlocking a PMV. For example, these systems may use camera-based face and helmet detection to determine that the transportation requestor is wearing a helmet.
Propulsion mechanisms (e.g., motors) of PMVs may operate at different power levels, with implications for safety (e.g., speed), efficiency (e.g., power consumption), and trip planning (e.g., whether a PMV will have sufficient power supply charge level to complete a trip). Systems described herein may use information about the use of the PMV (e.g., the incline on which the PMV is operating, the distance to a destination, etc.) to adjust the power level of the propulsion mechanism of the PMV according to the situation. In some examples, systems described herein may adjust the power level of the propulsion mechanism of the PMV based on the capabilities of the transportation requestor.
In some examples, systems described herein may use sensor data to determine the use of the PMV and/or the appropriate power level of the PMV. For example, systems described herein may use accelerometer data and/or gyroscope data to determine an incline on which the PMV is operating (and, e.g., provide greater power for uphill inclines and less power for flat and/or downhill inclines). Additionally or alternatively, systems described herein may use data from a torque sensor to determine an amount of torque applied by the propulsion mechanism of the PMV and adjust the power level of the propulsion mechanism of the PMV based on the determined torque.
In some examples, systems described herein may determine a route for a transportation requestor's trip based on a safety risk associated with alternative routes. For example, systems described herein may set a route based at least in part on a bike lane being within the route. As another example, systems described herein may set a route based at least in part on a hill being excluded from the route. In some examples, systems described herein may collect information about routes based on historical trips taken by a transportation requestor and/or other transportation requestors within a dynamic transportation network to determine a route for a PMV with an acceptable safety risk. For example, these systems may collect information on average and maximum speeds traveled by PMVs (e.g., within the dynamic transportation network) on various routes and/or transportation requestor feedback for various routes. In some examples, these systems may collect safety related data (e.g., number and severity of accidents). In some examples, these systems may detect potholes found in various routes (e.g., using sensor data from the PMV, including, e.g., accelerometer data). These systems may make future route determinations based on the collected pothole data. Additionally or alternatively, these systems may report pothole data (and/or any other road condition data) to municipalities.
As mentioned above, in some examples, systems described herein may determine the location of a PMV based on a variety of different methods. For example, systems may determine the location based on a GPS device integrated into the PMV. However, in some cases GPS information may be unavailable or imprecise. Accordingly, in some examples, systems described herein may use data from other transportation providers within a dynamic transportation network to determine the location of a PMV. For example, provider vehicles may include wireless communication devices capable of identifying and/or communicating with the PMV. Accordingly, systems described herein may determine the location of a PMV based at least in part on a location of a provider vehicle when the provider vehicle identifies the PMV via a wireless communication signal (e.g., a BLUETOOTH or WI-FI signal). In some examples, provider vehicles may include cameras, as systems described herein may determine the location of a PMV by receiving the location of a provider vehicle when the camera of a provider vehicle captures an image of the PMV. For example, a provider vehicle within a dynamic transportation network may travel past the PMV (e.g., while fulfilling a transportation request unrelated to the PMV). A camera within and/or mounted to the provider vehicle may capture street-level imagery (e.g., to produce street-level mapping data, to collect real-time street conditions for use within the dynamic transportation network, and/or to gather information about other vehicles within the dynamic transportation network). The street-level imagery captured by the provider vehicle may include an image of the PMV. By identifying the PMV from within the image of the PMV and correlating the image of the PMV with the location of the provider vehicle when the image was taken, systems described herein may determine a location of the PMV. In some examples, a PMV sensor may provide location information for the PMV. For example, the PMV may include a simultaneous localization and mapping (SLAM) system. Additionally or alternatively, the PMV may include a camera and systems described herein may determine the geolocation of the PMV based on a known location of a feature recognized in the camera of the PMV.
In some examples, systems described herein may use sensor information (e.g., from accelerometers and/or gyroscopes) to determine whether a PMV is tipped over. In some examples, these systems may determine, based at least in part on the PMV being tipped over (e.g., while traveling at speed) that an accident has occurred and/or that a PMV needs maintenance or service. Accordingly, the systems described herein may initiate contact with emergency services for the transportation requestor. In some examples, systems described herein may use sensor information (e.g., from accelerometers and/or gyroscopes) to determine that a PMV has been involved in an accident and record audio and/or video data from a period of time before the accident to a period of time after the accident has occurred.
In some examples, systems described herein may determine whether to apply brakes to front wheels or to back wheels based on sensor information. For example, systems described herein may derive motion information and/or weight distribution information to determine whether applying brakes at the front or the back would result in more safety and/or comfort for the transportation requestor.
In some examples, PMVs may include an anti-lock braking system which may function to reduce a safety risk. For example, a PMV may include one or more sensors (e.g., wheel rotation sensors) to detect locked brakes on the PMV and/or sliding wheels. Accordingly, systems described herein may engage an anti-lock braking system. In some examples, the anti-lock braking system may use sensor data available from the PMV (e.g., sensor data indicating the surface material on which the PMV is traveling) and/or historical usage data (e.g., data indicating the expected wear-and-tear on the wheels of the PMV based on past miles traveled and conditions traveled under derived from sensor data) to improve anti-lock braking performance.
In some examples, a PMV may autonomously reposition (e.g., to move toward a matched requestor and/or a location for meeting the requestor, to park in a dock or a virtual parking space, to move to a safe position, move to a geofenced virtual parking area, etc.). In some examples, the PMV may include a camera and the PMV may reposition based at least in part on the camera data (e.g., based on identified objects or locations from the image data).
In some examples, systems described herein may estimate the range of a PMV. These systems may estimate the range based on any of a variety of factors, including, without limitation, the charge of the charge storage device (e.g., battery), the temperature of the battery, the weight of the transportation requestor (e.g., based on strain gauge sensor data), the expected terrain of the route, and/or expected weather conditions (e.g., wind strength and direction).
In some examples, a PMV may include a rear-facing camera and systems described herein may alert a transportation requestor based on determining, in light of data from the rear-facing camera, that a collision is likely, that the transportation requestor is not looking at the road or otherwise is engaged with the ride, is not wearing a helmet or other safety equipment, and/or any other relevant situation.
As mentioned above, dynamic transportation matching system 110 may communicate with computing devices in each of vehicles 120. The computing devices may be any suitable type of computing device. In some examples, one or more of the computing devices may be integrated into the respective vehicles 120. In some examples, one or more of the computing devices may be mobile devices. For example, one or more of the computing devices may be smartphones. 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 provider for a transportation matching application, a navigation application, and/or any other application suited for the use of requestors and/or providers). 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 in order to provide transportation services to transportation requestors and/or communicate with dynamic transportation matching system 110.
As shown in
Embodiments of the instant disclosure may include or be implemented in conjunction with a dynamic transportation matching system. A transportation matching 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 an autonomous vehicle service, a personal mobility vehicle service, or some combination and/or derivative thereof. The transportation matching system may include and/or interface with any of a variety of subsystems that may implement, support, and/or improve a 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 navigation 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 reputation 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 computing system installed in a PMV, a server computer system, or any other hardware platform capable of providing transportation matching services to one or more requestors and/or providers. The computing devices implementing the transportation matching system may the same devices, similar devices, and/or different devices. For example, the transportation matching system may match a transportation requestor device with a transportation provider device associated with a car (or similar road-constrained vehicle), with a device associated with a personal mobility vehicle, and/or a combination thereof.
In addition to vehicles 220, in some examples dynamic transportation matching system 210 may also be in communication with vehicles 230. In some examples, vehicles 230 may not operate as a part of the dynamic transportation network. For example, dynamic transportation matching system 210 may not manage or direct vehicles 230. Instead, vehicles 230 may provide predictable and/or reliable transportation upon which dynamic transportation matching system 210 may rely when making matches. For example, vehicles 230 may include buses, subways, trains, and the like that may (i) run on fixed schedules known to dynamic transportation matching system 210 and/or (ii) make available information to transportation matching system 210 allowing transportation matching system 210 to predict departure and arrival times. While dynamic transportation matching system 210 may not manage or control vehicles 230, in some examples dynamic transportation matching system 210 may interact with systems that manage transportation provided by vehicles 230. For example, dynamic transportation matching system 210 may procure tickets to ride one or more vehicles 230 on behalf of one or more of requestors 240 and/or may notify one or more vehicles 230 of the status of one or more requestors 240. When dynamic transportation matching system 210 receives transportation requests from one or more of requestors 240, dynamic transportation matching system 210 may match the transportation request with one or more providers among vehicles 220 and/or vehicles 230 based on any of a variety of factors. For example, dynamic transportation matching system 210 may match the transportation request based on the current and/or projected location of and/or the current and/or projected availability of each candidate provider. In some examples, transportation matching system 210 may match the transportation request to a first provider instead of a second provider in order to maintain availability of the second provider for another current or prospective requestor. In some examples, dynamic transportation matching system 210 may match the transportation request based on a suitability of a candidate provider for the transportation request. For example, dynamic transportation matching system 210 may determine that a long-distance trip is suited for a road-going vehicle but may determine that a relatively short trip is suited for a personal mobility vehicle. In some examples, dynamic transportation matching system 210 may match a transportation request to multiple providers. For example, dynamic transportation matching system 210 may match a road-going vehicle to one leg of a trip, a mass transit vehicle to another leg of the trip, and a personal mobility vehicle to a third leg of the trip.
In some examples, PMV 501 may include echolocation sensor 509. Echolocation sensor 509 may function to detect objects in proximity to PMV 501. When echolocation sensor 509 detect objects which may collide with PMV 501, collision avoidance measures may be employed as described above. Echolocation sensor 509 may include, without limitation, a radar sensor, a lidar sensor, and an ultrasonic sensor.
In some examples, image sensor 510 may function to capture images of a transportation requestor. Images of the transportation requestor may be used to determine a level of focus and/or attention the transportation requestor is paying towards operating PMV 501. For example, image sensor 501 may capture images of a transportation requestor operating a device (e.g., smartphone) and determine whether operation of the device may increase a safety risk of PMV 501 operation. Image sensor 501 may determine if the transportation requestor operating PMV 501 is wearing safety equipment (e.g., safety helmet). In response, PMV 501 may provide feedback to the transportation requestor to wear safety equipment and/or increase attention and focus on PMV 501 operation. In response to determining the transportation requestor is not paying attention or operating PMV 501 in an unsafe manner, PMV 501 may decrease the speed of PMV 501 by applying the brakes and/or reducing power applied to a propulsion mechanism of PMV 501.
In some examples images of the transportation requestor captured by image sensor 510 may be used to determine a position of the transportation requestor on PMV 501. Image sensor 510 may determine the position will increase a safety risk of PMV 501 operation. In response, PMV 501 may provide feedback to the transportation requestor or decrease the speed of PMV 501 by applying the brakes and/or reducing power applied to a propulsion mechanism of PMV 501.
In some examples, PMV 501 may include weight sensor 521. Weight sensor 521 may function to determine the weight of a transportation requestor operating PMV 501. The weight of a transportation requestor operating PMV 501 may be used for various functions, including without limitation, matching transportation requestors to a PMV capable of safely handling the weight of the transportation requestor, controlling a speed of PMV 501 during operation on flat, uphill or downhill terrain, and controlling an anti-skid mechanism of PMV 501.
In some examples, PMV 501 may include torque sensor 522. Torque sensor 522 may function to determine the amount of torque applied to a drive mechanism of PMV 501. The torque sensor 522 may be used for various functions, including without limitation, controlling an amount of power delivered to a propulsion mechanism of PMV 501, controlling a charge level of a charge storage device of PMV 501, controlling a speed of PMV 501 during operation on flat, uphill or downhill terrain, and controlling an anti-skid mechanism of PMV 501.
In some examples, PMV 501 may include location sensor 512. Location sensor 512 may function to determine the location of PMV 501. The location of PMV 501 may be used for various functions, including without limitation, matching transportation requestors to PMV 501 for transportation service, determining a route the PMV is traveling, determining a type of terrain PMV 501 is operating on, determining if PMV 501 is operating in a geofence area, determining a distance to a destination of a transportation requestor, restricting a location of travel of PMV 501, and providing usage information to a dynamic transportation network. Location sensor 512 may include without limitation, a global navigation satellite system (e.g., global positioning system), Bluetooth™ low energy, dead reckoning, and radio wave triangulation (e.g., cellular and WiFi).
In some examples, PMV 501 may include biometric sensor 511. Biometric sensor 511 may function to detect characteristics of a transportation requestor operating PMV 501. Biometric sensor 511 may detect various characteristics of a transportation requestor, including but not limited to, a transportation requestor's fingerprint, iris, voice, pulse, blood pressure, face, body size, weight, body position, limb position, and gaze. Data collected from biometric sensor 511 may be used to reduce a safety risk in PMV operation in a variety of ways, including without limitation, authenticating a transportation requestor to operate PMV 501, determining a physical characteristic (e.g., height, weight, gender, age) of a transportation requestor operating PMV 501, and determining a health status (e.g., fatigue level) of a transportation requestor operating PMV 501. PMV 501 may use the characteristic information in a variety of ways, including without limitation, modifying a transportation function of PMV 501, locking and/or unlocking PMV 501, and reporting a potential health status risk.
In some examples, PMV 501 may include inclination sensor 513. Inclination sensor 513 may function to determine an angle of inclination of a terrain PMV 501 is operating on. Inclination sensor 513 may determine the angle of inclination (e.g., uphill, downhill, or flat) of the terrain and modify a transportation function of PMV 501 (as described in more detail below) in order to reduce a safety risk.
In some examples, PMV 501 may include front wheel rotation sensor 514 and rear wheel rotation sensor 515. Front wheel rotation sensor 514 and rear wheel rotation sensor 515 may function to determine a speed of PMV 501 and/or a state of operation of PMV 501. Wheel rotation sensors 514, 515 may determine a speed of PMV 501 is greater than a speed set for safe operation of PMV 501 and in response PMV 501 may reduce the speed by applying the brakes and/or reducing power applied to a propulsion mechanism of PMV 501. In some examples, front wheel rotation sensor 514 and rear wheel rotation sensor 515 may sense different rates of rotation during operation of PMV 501. When sensing different rates of wheel rotation PMV 501 may determine PMV 501 is not operating safely and in response an anti-skid control mechanism may be activated to bring PMV 501 back to a safe operating condition.
In some examples, PMV 501 may include charge level sensor 517. Charge level sensor 517 may function to determine a level of charge in a charge storage device (e.g. battery, capacitor, fuel cell, etc.) of PMV 501. PMV 501 may use the charge level to control a transportation function of PMV 501. For example, if the charge level is below a threshold, PMV 501 may reduce the speed of operation in order to conserve power and ensure the transportation requestor reaches their destination before depleting power. The charge level may also be used to determine a range of travel PMV 501 is capable of when matching a transportation requestor to PMV 501.
In some examples, PMV 501 may include inertial measurement sensor 520. Inertial measurement sensor 520 may function to determine a rate of linear and rotational acceleration of PMV 501. PMV 501 may use inertial measurement sensor 520 to control a transportation function of PMV 501. For example, inertial measurement sensor 520 may determine a pitch, yaw and/or roll direction of PMV 501 that indicates PMV 501 is not operating safely and/or is in an uncontrolled state. PMV 501 may use the pitch, yaw and/or roll information to control PMV 501 by controlling an anti-skid mechanism, a steering mechanism, a braking system and/or propulsion mechanism to bring PMV 501 back to a safe operating state. Inertial measurement sensor 520 may include a 3-directional axis accelerometer and a gyroscope. In some examples, inertial measurement sensor 520 may detect accelerations due to the effect of the terrain on PMV 501 and determine a type of terrain PMV 501 is operating on. In response, PMV 501 may adjust a maximum speed of PMV 501 and/or provide feedback the transportation requestor to move PMV 501 to a terrain which reduces a safety risk (e.g., a bike lane).
In some examples, PMV 601 may include audio feedback speaker 610. Audio feedback speaker 610 may function to provide audio feedback in the form of an audible signal to a transportation requestor operating PMV 601. Audio feedback speaker 610 may provide an audible signal as a warning signal tone and/or spoken language instructions to the transportation requestor. Audio feedback speaker 610 may provide audio feedback to a transportation requestor operating PMV 601 in response to an event that requires the transportation requestor's attention. For example, when PMV 601 has detected the transportation requestor is not operating PMV 601 safely and/or PMV 601 has detected a potential impending collision, audio feedback speaker 610 may provide a warning signal tone and/or instructions to the transportation requestor in order to draw attention to the event and instruct the transportation requestor to take corrective action. For example, if the transportation requestor is not wearing a helmet, audio feedback speaker 610 may provide an audio message requesting the transportation requestor to wear a helmet. For example, if the transportation requestor is operating PMV 601 in a restricted and/or unsafe geographic area (e.g., sidewalk, outside a geofence, a construction zone, etc.), audio feedback speaker 610 may provide an audio message requesting the transportation requestor to redirect PMV 601 to an unrestricted and/or safe geographic area.
In some examples, PMV 601 may include visual feedback device 611. Visual feedback device 611 may function to provide visual feedback to a transportation requestor operating PMV 601. Visual feedback device 610 may provide a visual signal in a variety of methods including without limitation, a warning light, displayed graphics, and displayed messages. In some examples, visual feedback device 611 may include without limitation, a warning light, a display screen, a head's up display screen, and a head mounted display. Visual feedback device 611 may provide visual feedback to a transportation requestor operating PMV 601 in response to an event that requires the transportation requestor's attention. For example, when PMV 601 has detected the transportation requestor is not operating PMV 601 safely and/or PMV 601 has detected a potential impending collision, visual feedback device 611 may provide a visual warning signal and/or instructions to the transportation requestor in order to draw attention to the event and instruct the transportation requestor to take corrective action. For example, if the transportation requestor is not wearing safety equipment (e.g., a helmet), visual feedback device 611 may provide a graphic and/or text message requesting the transportation requestor to wear a helmet. For example, if the transportation requestor is operating PMV 601 in a restricted and/or unsafe geographic area (e.g., sidewalk, outside a geofence, a construction zone), visual feedback device 611 may provide visual feedback requesting the transportation requestor to redirect PMV 601 to an unrestricted and/or safe geographic area. In some examples, visual feedback device 611 may display a map guiding the transportation requestor to a destination by using a travel route which reduces a safety risk.
In some examples, guardian 709 may modify a transportation function of PMV 714 by interacting with a graphical user interface (GUI) on guardian device 711. Guardian 709 may enter a transportation function modification parameter(s) into a GUI on guardian 709 and communicate the modification parameter(s) to dynamic transportation matching system 702 through network 712. Usage information module 704 may provide usage information and characteristic information of the transportation requestor to safety risk module 706. Usage information may include, without limitation, the location of operation of PMV 714, a body position of the transportation requestor operating PMV 714, a state of focus of the transportation requestor, a type of terrain PMV 714 is operating on, and an ambient environmental condition (e.g., weather) of PMV 714. Characteristic information of the transportation requestor may include, without limitation, physical attributes (e.g., height, weight), age, gender, a skill level of operating a PMV, and an experience level of operating a PMV.
In some examples, safety risk module 706 may analyze the modification parameter(s) based on the provided usage information and transportation requestor characteristic information to determine a safety risk associated with the requested modification(s). Based on the determined safety risk, safety risk module 706 may provide the modification parameter(s) to PMV control module 708. PMV control module 708 may provide transportation function modification commands to PMV 714 over network 710. PMV control module 708 may base the commands on the requested transportation function modification and characteristics of PMV 714. Characteristics of PMV 714 may include, without limitation, a type of PMV, a type of propulsion mechanism, a charge level of a charge storage device, and a type of PMV control system.
In some examples, modifying the at least one transportation function of the PMV while in use by the transportation requestor may comprise modifying a speed of the PMV.

In some embodiments, identity management services 1004 may be configured to perform authorization services for requestors and providers and/or manage their interactions and/or data with transportation management system 1002. This may include, e.g., authenticating the identity of providers and determining that they are authorized to provide services through transportation management system 1002. Similarly, requestors' identities may be authenticated to determine whether they are authorized to receive the requested services through transportation management system 1002. Identity management services 1004 may also manage and/or control access to provider and/or requestor data maintained by transportation management system 1002, such as driving and/or ride histories, vehicle data, personal data, preferences, usage patterns as a ride provider and/or as a ride requestor, profile pictures, linked third-party accounts (e.g., credentials for music and/or entertainment services, social-networking systems, calendar systems, task-management systems, etc.) and any other associated information. Transportation management system 1002 may also manage and/or control access to provider and/or requestor data stored with and/or obtained from third-party systems. For example, a requester or provider may grant transportation management system 1002 access to a third-party email, calendar, or task management system (e.g., via the user's credentials). As another example, a requestor or provider may grant, through a mobile device (e.g., 1016, 1020, 1022, or 1024), a transportation application associated with transportation management system 1002 access to data provided by other applications installed on the mobile device. In some examples, such data may be processed on the client and/or uploaded to transportation management system 1002 for processing.
In some embodiments, transportation management system 1002 may provide ride services 1008, which may include ride matching and/or management services to connect a requestor to a provider. For example, after identity management services module 1004 has authenticated the identity a ride requestor, ride services module 1008 may attempt to match the requestor with one or more ride providers. In some embodiments, ride services module 1008 may identify an appropriate provider using location data obtained from location services module 1006. Ride services module 1008 may use the location data to identify providers who are geographically close to the requestor (e.g., within a certain threshold distance or travel time) and/or who are otherwise a good match with the requestor. Ride services module 1008 may implement matching algorithms that score providers based on, e.g., preferences of providers and requestors; vehicle features, amenities, condition, and/or status; providers' preferred general travel direction and/or route, range of travel, and/or availability; requestors' origination and destination locations, time constraints, and/or vehicle feature needs; and any other pertinent information for matching requestors with providers. In some embodiments, ride services module 1008 may use rule-based algorithms and/or machine-learning models for matching requestors and providers.
