The present disclosure relates generally to transportation systems, and more specifically to systems and methods for determining a vehicle boarding score.
Many cities all over the world have successfully implemented public transportation systems which are widely used by people. Regular users of a public transportation system may rely on the system for commuting to work or school. Others may use it to meet up with friends, attend an event, or travel in general from one location to another. Despite the advantages that come from having access to a mass transit system, there are challenges that individuals will encounter when attempting to use the system as well. In some instances, it may be difficult to gauge whether an individual will arrive at a location for boarding a vehicle prior to the vehicle departing the location.
The present disclosure overcomes the shortcomings of prior technologies. In particular, a novel approach for determining a vehicle boarding score is provided, as detailed below.
In accordance with an aspect of the disclosure, a method for determining a vehicle boarding score is provided. The method includes analyzing the traffic data along the route. The method also includes based on the analysis, determining a vehicle boarding score for boarding the vehicle at the one or more stops.

The non-transitory computer-readable storage medium includes one or more sequences of one or more instructions for execution by one or more processors of a device. The one or more instructions which, when executed by the one or more processors, cause the device to receive traffic data corresponding to a vehicle along a route. The route includes one or more stops for boarding the vehicle. The one or more instructions further cause the device to analyze the traffic data along the route. The one or more instructions further cause the device to, based on the analysis, determine a vehicle boarding score for boarding the vehicle along the route at the one or more stops. The one or more instructions further cause the device to provide for display, via the display screen, the vehicle boarding score.
In accordance with another aspect of the disclosure, an apparatus is provided. The apparatus includes a processor. The apparatus also includes a memory comprising computer program code for one or more programs. The computer program code is configured to cause the processor of the apparatus to receive traffic data corresponding to a vehicle along a route. The route includes one or more stops for boarding the vehicle. The computer program code is further configured to cause the processor of the apparatus to receive map data corresponding to a mobile device. The computer program code is further configured to cause the processor of the apparatus to analyze the traffic data, the map data, or a combination thereof. The computer program code is further configured to cause the processor of the apparatus to, based on the analysis, determine a vehicle boarding score for boarding the vehicle at the one or more stops

In one embodiment, the vehicle 105 may be a standard gasoline powered vehicle, a hybrid vehicle, an electric vehicle, a fuel cell vehicle, and/or any other mobility implement type of vehicle. The vehicle 105 includes parts related to mobility, such as a powertrain with an engine, a transmission, a suspension, a driveshaft, and/or wheels, etc. In another example, the vehicle 105 may be an autonomous vehicle. The autonomous vehicle may be a manually controlled vehicle, semi-autonomous vehicle (e.g., some routine motive functions, such as parking, are controlled by the vehicle), or an autonomous vehicle (e.g., motive functions are controlled by the vehicle without direct driver input). In one example, the vehicle 105 may be a public transport vehicle such as a bus, a train, or a light rail vehicle.
The autonomous level of a vehicle can be a Level 0 autonomous level that corresponds to no automation for the vehicle, a Level 1 autonomous level that corresponds to a certain degree of driver assistance for the vehicle, a Level 2 autonomous level that corresponds to partial automation for the vehicle, a Level 3 autonomous level that corresponds to conditional automation for the vehicle, a Level 4 autonomous level that corresponds to high automation for the vehicle, a Level 5 autonomous level that corresponds to full automation for the vehicle, and/or another sub-level associated with a degree of autonomous driving for the vehicle. In one embodiment, user equipment (e.g., a mobile phone, a portable electronic device, etc.) may be integrated in the vehicle, which may include assisted driving vehicles such as autonomous vehicles, highly assisted driving (HAD), and advanced driving assistance systems (ADAS). Any of these assisted driving systems may be incorporated into the user equipment. Alternatively, an assisted driving device may be included in the vehicle.
The term autonomous vehicle may refer to a self-driving or driverless mode in which no passengers are required to be on board to operate the vehicle. An autonomous vehicle may be referred as a robot vehicle or an automated vehicle. The autonomous vehicle may include passengers, but no driver is necessary. These autonomous vehicles may park themselves or move packages between locations without a human operator. Autonomous vehicles may include multiple modes and transition between the modes. The autonomous vehicle may steer, brake, or accelerate and respond to lane marking indicators (lane marking type, lane marking intensity, lane marking color, lane marking offset, lane marking width, or other characteristics) and driving commands or navigation commands.
In one embodiment, the vehicle 105 may be an HAD vehicle or an ADAS vehicle. An HAD vehicle may refer to a vehicle that does not completely replace the human operator. Instead, in a highly assisted driving mode, the vehicle may perform some driving functions and the human operator may perform some driving functions. Vehicles may also be driven in a manual mode in which the human operator exercises a degree of control over the movement of the vehicle. The vehicles may also include a completely driverless mode. Other levels of automation are possible. The HAD vehicle may control the vehicle through steering or braking in response to the on the position of the vehicle and may respond to lane marking indicators (lane marking type, lane marking intensity, lane marking color, lane marking offset, lane marking width, or other characteristics) and driving commands or navigation commands. Similarly, ADAS vehicles include one or more partially automated systems in which the vehicle alerts the driver. The features are designed to avoid collisions automatically. Features may include adaptive cruise control, automate braking, or steering adjustments to keep the driver in the correct lane. ADAS vehicles may issue warnings for the driver based on the position of the vehicle or based on the lane marking indicators (lane marking type, lane marking intensity, lane marking color, lane marking offset, lane marking width, or other characteristics) and driving commands or navigation commands.
In one embodiment, the user equipment (UE) 109 may be, or include, an embedded system, mobile terminal, fixed terminal, or portable terminal including a built-in navigation system, a personal navigation device, mobile handset, station, unit, device, multimedia computer, multimedia tablet, Internet node, communicator, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, personal communication system (PCS) device, personal digital assistants (PDAs), audio/video player, digital camera/camcorder, positioning device, fitness device, television receiver, radio broadcast receiver, electronic book device, game device, or any combination thereof, including the accessories and peripherals of these devices, or any combination thereof. It is also contemplated that the UE 109 may support any type of interface with a user (e.g., by way of various buttons, touch screens, consoles, displays, speakers, “wearable” circuitry, and other I/O elements or devices). Although shown in
In one embodiment, the UE 109, may execute one or more applications 117 (e.g., software applications) configured to carry out steps in accordance with methods described here. For instance, in one non-limiting example, the application 117 may carry out steps for determining a vehicle boarding score. In another non-limiting example, application 117 may also be any type of application that is executable on the UE 109 and/or vehicle 105, such as autonomous driving applications, mapping applications, location-based service applications, navigation applications, content provisioning services, camera/imaging application, media player applications, social networking applications, calendar applications, and the like. In yet another non-limiting example, the application 117 may act as a client for the data analysis system 103 and perform one or more functions associated with determining a vehicle boarding score, either alone or in combination with the data analysis system 103.
In some embodiments, the UE 109 and/or the vehicle 105 may include various sensors for acquiring a variety of different data or information. For instance, the UE 109 and/or the vehicle 105 may include one or more camera/imaging devices for capturing imagery (e.g., terrestrial images), global positioning system (GPS) sensors or Global Navigation Satellite System (GNSS) sensors for gathering location or coordinates data, network detection sensors for detecting wireless signals, receivers for carrying out different short-range communications (e.g., Bluetooth, Wi-Fi, Li-Fi, near field communication (NFC) etc.), temporal information sensors, Light Detection and Ranging (LIDAR) sensors, Radio Detection and Ranging (RADAR) sensors, audio recorders for gathering audio data, velocity sensors, switch sensors for determining whether one or more vehicle switches are engaged, and others.
The UE 109 and/or the vehicle 105 may also include one or more light sensors, height sensors, accelerometers (e.g., for determining acceleration and vehicle orientation), magnetometers, gyroscopes, inertial measurement units (IMUs), tilt sensors (e.g., for detecting the degree of incline or decline), moisture sensors, pressure sensors, and so forth. Further, the UE 109 and/or the vehicle 105 may also include sensors for detecting the relative distance of the vehicle 105 from a lane or roadway, the presence of other vehicles, pedestrians, traffic lights, lane markings, speed limits, road dividers, potholes, and any other objects, or a combination thereof. Other sensors may also be configured to detect weather data, traffic information, or a combination thereof. Yet other sensors may also be configured to determine the status of various control elements of the car, such as activation of wipers, use of a brake pedal, use of an acceleration pedal, angle of the steering wheel, activation of hazard lights, activation of head lights, and so forth.
In some embodiments, the UE 109 and/or the vehicle 105 may include GPS, GNSS or other satellite-based receivers configured to obtain geographic coordinates from a satellite 119 for determining current location and time. Further, the location can be determined by visual odometry, triangulation systems such as A-GPS, Cell of Origin, or other location extrapolation technologies, and so forth. In some embodiments, two or more sensors or receivers may be co-located with other sensors on the UE 109 and/or the vehicle 105.
By way of example, the map platform 101, the services platform 113, and/or the one or more content providers 111a-111n communicate with each other and other components of the system 100 using well known, new or still developing protocols. In this context, a protocol includes a set of rules defining how the network nodes within the communication network 115 interact with each other based on information sent over the communication links. The protocols are effective at different layers of operation within each node, from generating and receiving physical signals of various types, to selecting a link for transferring those signals, to the format of information indicated by those signals, to identifying which software application executing on a computer system sends or receives the information. The conceptually different layers of protocols for exchanging information over a network are described in the Open Systems Interconnection (OSI) Reference Model.
Communications between the network nodes are typically affected by exchanging discrete packets of data. Each packet typically comprises (1) header information associated with a particular protocol, and (2) payload information that follows the header information and contains information that may be processed independently of that particular protocol. In some protocols, the packet includes (3) trailer information following the payload and indicating the end of the payload information. The header includes information such as the source of the packet, its destination, the length of the payload, and other properties used by the protocol. Often, the data in the payload for the particular protocol includes a header and payload for a different protocol associated with a different, higher layer of the OSI Reference Model. The header for a particular protocol typically indicates a type for the next protocol contained in its payload. The higher layer protocol is said to be encapsulated in the lower layer protocol. The headers included in a packet traversing multiple heterogeneous networks, such as the Internet, typically include a physical (layer 1) header, a data-link (layer 2) header, an internetwork (layer 3) header and a transport (layer 4) header, and various application (layer 5, layer 6, and layer 7) headers as defined by the OSI Reference Model.
In one embodiment, the system 100 of
In one example, the system 100 of
In one embodiment, the system 100 may be configured to classify the vehicle boarding scores into two categories, low and high. In one example, the system 100 is configured to determine that the traffic along road segment 204 is heavier than usual based on the number of vehicles traveling along the road segment 204, as shown in
In one example, the individual 208 may access the vehicle boarding score associated with the vehicle 202 via a mobile device (e.g., UE 109 of
In another example, the system 100 is configured to receive map data corresponding to a mobile device associated with the individual 208 and the vehicle stop 210. In one example, the system 100, based on the map data (e.g., crosswalk information, number of traffic lights, etc.), may be configured to determine an expected time of travel for reaching the vehicle stop 210 based on the current location of the individual 208. In this example, the, system 100 may be configured to determine the distance required to reach the vehicle stop 210 in addition to the average time that it takes to cross the road segment 204 based on the current location of the individual 208. Based on the analysis of the map data, the system 100 may be configured to modify the vehicle boarding score. In one example, the system 100 may be configured to decrease the vehicle boarding score from high to low based on the analysis of the map data. In one example, the system 100 may provide a notification to the individual 208, via the mobile device, that the vehicle boarding score has been modified to low and provide one or more suggested actions in response to the modification to the vehicle boarding score.

In one embodiment, the system 100 of
In one example, the system 100 of
In one example, the system 100 is configured to determine that based on the relative position of the individuals 504, 508, and 512 to the vehicle 502 that the vehicle boarding score for boarding the vehicle 502 at the vehicle stop 518 is high. In one example, the system 100 is configured to determine that the vehicle boarding score remains high for the individual 504 moving in the direction 506 towards the vehicle 502. In this example, the system 100 is configured to determine that the vehicle boarding score also remains high for the individual 512 moving in the direction 514 towards the vehicle 502. Continuing with this example, the system 100 is configured to determine that the vehicle boarding score is subject to change based on the individual 508 continuing to move in the direction 510 away from the vehicle 502. In one example, the system 100 may provide a notification to the individual 508 that the vehicle boarding score may soon be modified to low based on the individual 508 getting farther way from the vehicle 502 while traveling away from the vehicle 502.
In one embodiment, geographic features (e.g., two-dimensional or three-dimensional features) are represented using polygons (e.g., two-dimensional features) or polygon extrusions (e.g., three-dimensional features). For example, the edges of the polygons correspond to the boundaries or edges of the respective geographic feature. In the case of a building, a two-dimensional polygon can be used to represent a footprint of the building, and a three-dimensional polygon extrusion can be used to represent the three-dimensional surfaces of the building. It is contemplated that although various embodiments are discussed with respect to two-dimensional polygons, it is contemplated that the embodiments are also applicable to three-dimensional polygon extrusions, models, routes, etc. Accordingly, the terms polygons and polygon extrusions/models as used herein can be used interchangeably.
In one embodiment, the following terminology applies to the representation of geographic features in the geographic database 107.
“Node”— A point that terminates a link.
“Line segment”— A straight line connecting two points.
“Link” (or “edge”)— A contiguous, non-branching string of one or more line segments terminating in a node at each end.
“Shape point”— A point along a link between two nodes (e.g., used to alter a shape of the link without defining new nodes).
“Oriented link”— A link that has a starting node (referred to as the “reference node”) and an ending node (referred to as the “non reference node”).
“Simple polygon”—An interior area of an outer boundary formed by a string of oriented links that begins and ends in one node. In one embodiment, a simple polygon does not cross itself.
“Polygon”—An area bounded by an outer boundary and none or at least one interior boundary (e.g., a hole or island). In one embodiment, a polygon is constructed from one outer simple polygon and none or at least one inner simple polygon. A polygon is simple if it just consists of one simple polygon, or complex if it has at least one inner simple polygon.
In one embodiment, the geographic database 107 follows certain conventions. For example, links do not cross themselves and do not cross each other except at a node or vertex. Also, there are no duplicated shape points, nodes, or links. Two links that connect each other have a common node or vertex. In the geographic database 107, overlapping geographic features are represented by overlapping polygons. When polygons overlap, the boundary of one polygon crosses the boundary of the other polygon. In the geographic database 107, the location at which the boundary of one polygon intersects they boundary of another polygon is represented by a node. In one embodiment, a node may be used to represent other locations along the boundary of a polygon than a location at which the boundary of the polygon intersects the boundary of another polygon. In one embodiment, a shape point is not used to represent a point at which the boundary of a polygon intersects the boundary of another polygon.
In one embodiment, the geographic database 107 is presented according to a hierarchical or multi-level tile projection. More specifically, in one embodiment, the geographic database 107 may be defined according to a normalized Mercator projection. Other projections may be used. In one embodiment, a map tile grid of a Mercator or similar projection can a multilevel grid. Each cell or tile in a level of the map tile grid is divisible into the same number of tiles of that same level of grid. In other words, the initial level of the map tile grid (e.g., a level at the lowest zoom level) is divisible into four cells or rectangles. Each of those cells are in turn divisible into four cells, and so on until the highest zoom level of the projection is reached.
In one embodiment, the map tile grid may be numbered in a systematic fashion to define a tile identifier (tile ID). For example, the top left tile may be numbered 00, the top right tile may be numbered 01, the bottom left tile may be numbered 10, and the bottom right tile may be numbered 11. In one embodiment, each cell is divided into four rectangles and numbered by concatenating the parent tile ID and the new tile position. A variety of numbering schemes also is possible. Any number of levels with increasingly smaller geographic areas may represent the map tile grid. Any level (n) of the map tile grid has 2(n+1) cells. Accordingly, any tile of the level (n) has a geographic area of A/2(n+1) where A is the total geographic area of the world or the total area of the map tile grids. Because of the numbering system, the exact position of any tile in any level of the map tile grid or projection may be uniquely determined from the tile ID.
In one embodiment, the system 100 may identify a tile by a quadkey determined based on the tile ID of a tile of the map tile grid. The quadkey, for example, is a one dimensional array including numerical values. In one embodiment, the quadkey may be calculated or determined by interleaving the bits of the row and column coordinates of a tile in the grid at a specific level. The interleaved bits may be converted to a predetermined base number (e.g., base 10, base 4, hexadecimal). In one example, leading zeroes are inserted or retained regardless of the level of the map tile grid in order to maintain a constant length for the one-dimensional array of the quadkey. In another example, the length of the one-dimensional array of the quadkey may indicate the corresponding level within the map tile grid. In one embodiment, the quadkey is an example of the hash or encoding scheme of the respective geographical coordinates of a geographical data point that can be used to identify a tile in which the geographical data point is located.
In exemplary embodiments, the road segment data records 605 are links or segments representing roads, streets, or paths, as can be used in the calculated route or recorded route information for determination of one or more personalized routes, according to exemplary embodiments. The node data records 603 are end points or vertices (such as intersections) corresponding to the respective links or segments of the road segment data records 605. The road segment data records 605 and the node data records 603 represent a road network, such as used by vehicles, cars, and/or other entities. Alternatively, the geographic database 107 can contain path segment and node data records or other data that represent pedestrian paths or areas in addition to or instead of the vehicle road record data, for example. In one embodiment, the road or path segments can include an altitude component to extend to paths or road into three-dimensional space (e.g., to cover changes in altitude and contours of different map features, and/or to cover paths traversing a three-dimensional airspace).
The road/link segments and nodes can be associated with attributes, such as geographic coordinates, street names, address ranges, speed limits, turn restrictions at intersections, and other navigation related attributes, as well as POIs, such as gasoline stations, hotels, restaurants, museums, stadiums, offices, automobile dealerships, auto repair shops, buildings, stores, parks, etc. The geographic database 107 can include data about the POIs and their respective locations in the POI data records 607. In one example, the POI data records 607 may include the hours of operation for various businesses. The geographic database 107 can also include data about places, such as cities, towns, or other communities, and other geographic features, such as bodies of water, mountain ranges, etc. Such place or feature data can be part of the POI data records 607 or can be associated with POIs or POI data records 607 (such as a data point used for displaying or representing a position of a city).
In one embodiment, other data records 609 include cartographic (“carto”) data records, routing data, weather data, and maneuver data. In one example, the other data records 609 include data that is associated with certain POIs, roads, or geographic areas. In one example, the data is stored for utilization by a third-party. In one embodiment, the other data records 609 include traffic data records such as traffic data reports. In one example, the traffic data reports are based on historical data. In another example, the traffic data reports are based on real-time traffic data reports. In one embodiment, the other data records 609 include event data. In one example, the event data includes information about upcoming events such as start time, end time, impact to access to one or more road segments, etc. In one example, the event data includes transit data such as train or bus schedules. In one embodiment, the other data records 609 include weather data records such as weather data reports. For example, the weather data records can be associated with any of the map features stored in the geographic database 107 (e.g., a specific road or link, node, intersection, area, POI, etc.) on which the weather data was collected. In another example, the other data records 609 can be associated with crosswalk information, traffic light times, traffic light signals, etc. One or more portions, components, areas, layers, features, text, and/or symbols of the POI or event data can be stored in, linked to, and/or associated with one or more of these data records. For example, one or more portions of the POI, event data, or recorded route information can be matched with respective map or geographic records via position or GPS data associations (such as using the point-based map matching embodiments describes herein), for example.
In one embodiment, the geographic database 107 may also include point data records for storing the point data, map features, as well as other related data used according to the various embodiments described herein. In addition, the point data records can also store ground truth training and evaluation data, machine learning models, annotated observations, and/or any other data. By way of example, the point data records can be associated with one or more of the node data records 603, road segment data records 605, and/or POI data records 607 to support verification, localization or visual odometry based on the features stored therein and the corresponding estimated quality of the features. In this way, the point data records can also be associated with or used to classify the characteristics or metadata of the corresponding records 603, 605, and/or 607.
As discussed above, the HD data records 611 may include models of road surfaces and other map features to centimeter-level or better accuracy. The HD data records 611 may also include models that provide the precise lane geometry with lane boundaries, as well as rich attributes of the lane models. These rich attributes may include, but are not limited to, lane traversal information, lane types, lane marking types, lane level speed limit information, and/or the like. In one embodiment, the HD data records 611 may be divided into spatial partitions of varying sizes to provide HD mapping data to vehicles and other end user devices with near real-time speed without overloading the available resources of these vehicles and devices (e.g., computational, memory, bandwidth, etc. resources). In some implementations, the HD data records 611 may be created from high-resolution 3D mesh or point-cloud data generated, for instance, from LiDAR-equipped vehicles. The 3D mesh or point-cloud data may be processed to create 3D representations of a street or geographic environment at centimeter-level accuracy for storage in the HD data records 611.
In one embodiment, the HD data records 611 also include real-time sensor data collected from probe vehicles in the field. The real-time sensor data, for instance, integrates real-time traffic information, weather, and road conditions (e.g., potholes, road friction, road wear, etc.) with highly detailed 3D representations of street and geographic features to provide precise real-time also at centimeter-level accuracy. Other sensor data can include vehicle telemetry or operational data such as windshield wiper activation state, braking state, steering angle, accelerator position, and/or the like.

The geographic database 107 can be maintained by the one or more content providers 111a-111n in association with the services platform 113 (e.g., a map developer). The map developer can collect geographic data to generate and enhance the geographic database 107. There can be different ways used by the map developer to collect data. These ways can include obtaining data from other sources, such as municipalities or respective geographic authorities. In addition, the map developer can employ field personnel to travel by vehicle along roads throughout the geographic region to observe features and/or record information about them, for example. Also, remote sensing, such as aerial or satellite photography, can be used.
The geographic database 107 can be a master geographic database stored in a format that facilitates updating, maintenance, and development. For example, the master geographic database 107 or data in the master geographic database 107 can be in an Oracle spatial format or other spatial format (for example, accommodating different map layers), such as for development or production purposes. The Oracle spatial format or development/production database can be compiled into a delivery format, such as a geographic data files (GDF) format. The data in the production and/or delivery formats can be compiled or further compiled to form geographic database products or databases, which can be used in end user navigation devices or systems.
For example, geographic data is compiled (such as into a platform specification format (PSF) format) to organize and/or configure the data for performing navigation-related functions and/or services, such as route calculation, route guidance, map display, speed calculation, distance and travel time functions, and other functions, by a navigation device. The navigation-related functions can correspond to vehicle navigation, pedestrian navigation, or other types of navigation. The compilation to produce the end user databases can be performed by a party or entity separate from the map developer. For example, a customer of the map developer, such as a navigation device developer or other end user device developer, can perform compilation on a received geographic database in a delivery format to produce one or more compiled navigation databases.

The processes described herein for determining a vehicle boarding score may be advantageously implemented via software, hardware (e.g., general processor, Digital Signal Processing (DSP) chip, an Application Specific Integrated Circuit (ASIC), Field Programmable Gate Arrays (FPGAs), etc.), firmware or a combination thereof. Such exemplary hardware for performing the described functions is detailed below.
A bus 1110 includes one or more parallel conductors of information so that information is transferred quickly among devices coupled to the bus 1110. One or more processors 1102 for processing information are coupled with the bus 1110.
A processor 1102 performs a set of operations on information as specified by computer program code related to determining a vehicle boarding score. The computer program code is a set of instructions or statements providing instructions for the operation of the processor and/or the computer system to perform specified functions. The code, for example, may be written in a computer programming language that is compiled into a native instruction set of the processor. The code may also be written directly using the native instruction set (e.g., machine language). The set of operations include bringing information in from the bus 1110 and placing information on the bus 1110. The set of operations also typically include comparing two or more units of information, shifting positions of units of information, and combining two or more units of information, such as by addition or multiplication or logical operations like OR, exclusive OR (XOR), and AND. Each operation of the set of operations that can be performed by the processor is represented to the processor by information called instructions, such as an operation code of one or more digits. A sequence of operations to be executed by the processor 1102, such as a sequence of operation codes, constitute processor instructions, also called computer system instructions or, simply, computer instructions. Processors may be implemented as mechanical, electrical, magnetic, optical, chemical or quantum components, among others, alone or in combination.
Computer system 1100 also includes a memory 1104 coupled to bus 1110. The memory 1104, such as a random-access memory (RAM) or other dynamic storage device, stores information including processor instructions for determining a vehicle boarding score. Dynamic memory allows information stored therein to be changed by the computer system 1100. RAM allows a unit of information stored at a location called a memory address to be stored and retrieved independently of information at neighboring addresses. The memory 1104 is also used by the processor 1102 to store temporary values during execution of processor instructions. The computer system 1100 also includes a read only memory (ROM) 1106 or other static storage device coupled to the bus 1110 for storing static information, including instructions, that is not changed by the computer system 1100. Some memory is composed of volatile storage that loses the information stored thereon when power is lost. Also coupled to bus 1110 is a non-volatile (persistent) storage device 1108, such as a magnetic disk, optical disk or flash card, for storing information, including instructions, that persists even when the computer system 1100 is turned off or otherwise loses power.
Information, including instructions for determining a vehicle boarding score, is provided to the bus 1110 for use by the processor from an external input device 1112, such as a keyboard containing alphanumeric keys operated by a human user, or a sensor. A sensor detects conditions in its vicinity and transforms those detections into physical expression compatible with the measurable phenomenon used to represent information in the computer system 1100. Other external devices coupled to bus 1110, used primarily for interacting with humans, include a display 1114, such as a cathode ray tube (CRT) or a liquid crystal display (LCD), or plasma screen or printer for presenting text or images, and a pointing device 1116, such as a mouse or a trackball or cursor direction keys, or motion sensor, for controlling a position of a small cursor image presented on the display 1114 and issuing commands associated with graphical elements presented on the display 1114. In some embodiments, for example, in embodiments in which the computer system 1100 performs all functions automatically without human input, one or more of external input device 1112, display device 1114 and pointing device 1116 is omitted.
In the illustrated embodiment, special purpose hardware, such as an application specific integrated circuit (ASIC) 1120, is coupled to bus 1110. The special purpose hardware is configured to perform operations not performed by processor 1102 quickly enough for special purposes. Examples of application specific ICs include graphics accelerator cards for generating images for display 1114, cryptographic boards for encrypting and decrypting messages sent over a network, speech recognition, and interfaces to special external devices, such as robotic arms and medical scanning equipment that repeatedly perform some complex sequence of operations that are more efficiently implemented in hardware.
The computer system 1100 may also include one or more instances of a communications interface 1170 coupled to bus 1110. The communication interface 1170 may provide a one-way or two-way communication coupling to a variety of external devices that operate with their own processors, such as printers, scanners and external disks. In addition, the communication interface 1170 may provide a coupling to a local network 1180, by way of a network link 1178. The local network 1180 may provide access to a variety of external devices and systems, each having their own processors and other hardware. For example, the local network 1180 may provide access to a host 1182, or an internet service provider 1184, or both, as shown in
The computer system 1100 also includes one or more instances of a communication interface 1170 coupled to bus 1110. Communication interface 1170 provides a one-way or two-way communication coupling to a variety of external devices that operate with their own processors, such as printers, scanners and external disks. In general, the coupling is with a network link 1178 that is connected to a local network 1180 to which a variety of external devices with their own processors are connected. For example, communication interface 1170 may be a parallel port or a serial port or a universal serial bus (USB) port on a personal computer. In some embodiments, the communication interface 1170 is an integrated services digital network (ISDN) card or a digital subscriber line (DSL) card or a telephone modem that provides an information communication connection to a corresponding type of telephone line. In some embodiments, a communication interface 1170 is a cable modem that converts signals on bus 1110 into signals for a communication connection over a coaxial cable or into optical signals for a communication connection over a fiber optic cable. As another example, the communication interface 1170 may be a local area network (LAN) card to provide a data communication connection to a compatible LAN, such as Ethernet. Wireless links may also be implemented. For wireless links, the communication interface 1170 sends or receives or both sends and receives electrical, acoustic or electromagnetic signals, including infrared and optical signals, that carry information streams, such as digital data. For example, in wireless handheld devices, such as mobile telephones like cell phones, the communication interface 1170 includes a radio band electromagnetic transmitter and receiver called a radio transceiver. In certain embodiments, the communication interface 1170 enables connection to the communication network 115 of
The term computer-readable medium is used herein to refer to any medium that participates in providing information to processor 1102, including instructions for execution. Such a medium may take many forms, including, but not limited to, non-volatile media, volatile media and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as storage device 1108. Volatile media include, for example, dynamic memory 1104. Transmission media include, for example, coaxial cables, copper wire, fiber optic cables, and carrier waves that travel through space without wires or cables, such as acoustic waves and electromagnetic waves, including radio, optical and infrared waves. Signals include man-made transient variations in amplitude, frequency, phase, polarization or other physical properties transmitted through the transmission media. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, CDRW, DVD, any other optical medium, punch cards, paper tape, optical mark sheets, any other physical medium with patterns of holes or other optically recognizable indicia, a RAM, a PROM, an EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read.
In one embodiment, the chip set 1200 includes a communication mechanism such as a bus 1201 for passing information among the components of the chip set 1200. A processor 1203 has connectivity to the bus 1201 to execute instructions and process information stored in, for example, a memory 1205. The processor 1203 may include one or more processing cores with each core configured to perform independently. A multi-core processor enables multiprocessing within a single physical package. Examples of a multi-core processor include two, four, eight, or greater numbers of processing cores. Alternatively, or in addition, the processor 1203 may include one or more microprocessors configured in tandem via the bus 1201 to enable independent execution of instructions, pipelining, and multithreading. The processor 1203 may also be accompanied with one or more specialized components to perform certain processing functions and tasks such as one or more digital signal processors (DSP) 1207, or one or more application-specific integrated circuits (ASIC) 1209. A DSP 1207 typically is configured to process real-world signals (e.g., sound) in real time independently of the processor 1203. Similarly, an ASIC 1209 can be configured to performed specialized functions not easily performed by a general purposed processor. Other specialized components to aid in performing the inventive functions described herein include one or more field programmable gate arrays (FPGA) (not shown), one or more controllers (not shown), or one or more other special-purpose computer chips.
The processor 1203 and accompanying components have connectivity to the memory 1205 via the bus 1201. The memory 1205 includes both dynamic memory (e.g., RAM, magnetic disk, writable optical disk, etc.) and static memory (e.g., ROM, CD-ROM, etc.) for storing executable instructions that when executed perform the steps described herein to provide information for determining a vehicle boarding score. The memory 1205 also stores the data associated with or generated by the execution of the inventive steps.
A radio section 1315 amplifies power and converts frequency in order to communicate with a base station, which is included in a mobile communication system, via antenna 1317. The power amplifier (PA) 1319 and the transmitter/modulation circuitry are operationally responsive to the MCU 1303, with an output from the PA 1319 coupled to the duplexer 1321 or circulator or antenna switch, as known in the art. The PA 1319 also couples to a battery interface and power control unit 1320.
In use, a user of mobile terminal 1301 speaks into the microphone 1311 and his or her voice along with any detected background noise is converted into an analog voltage. The analog voltage is then converted into a digital signal through the Analog to Digital Converter (ADC) 1323. The control unit 1303 routes the digital signal into the DSP 1305 for processing therein, such as speech encoding, channel encoding, encrypting, and interleaving. In one embodiment, the processed voice signals are encoded, by units not separately shown, using a cellular transmission protocol such as global evolution (EDGE), general packet radio service (GPRS), global system for mobile communications (GSM), Internet protocol multimedia subsystem (IMS), universal mobile telecommunications system (UMTS), etc., as well as any other suitable wireless medium, e.g., microwave access (WiMAX), Long Term Evolution (LTE) networks, 5G networks, code division multiple access (CDMA), wireless fidelity (WiFi), satellite, and the like.
The encoded signals are then routed to an equalizer 1325 for compensation of any frequency-dependent impairments that occur during transmission though the air such as phase and amplitude distortion. After equalizing the bit stream, the modulator 1327 combines the signal with a RF signal generated in the RF interface 1329. The modulator 1327 generates a sine wave by way of frequency or phase modulation. In order to prepare the signal for transmission, an up-converter 1331 combines the sine wave output from the modulator 1327 with another sine wave generated by a synthesizer 1333 to achieve the desired frequency of transmission. The signal is then sent through a PA 1319 to increase the signal to an appropriate power level. In practical systems, the PA 1319 acts as a variable gain amplifier whose gain is controlled by the DSP 1305 from information received from a network base station. The signal is then filtered within the duplexer 1321 and optionally sent to an antenna coupler 1335 to match impedances to provide maximum power transfer. Finally, the signal is transmitted via antenna 1317 to a local base station. An automatic gain control (AGC) can be supplied to control the gain of the final stages of the receiver. The signals may be forwarded from there to a remote telephone which may be another cellular telephone, other mobile phone or a landline connected to a Public Switched Telephone Network (PSTN), or other telephony networks.
Voice signals transmitted to the mobile terminal 1301 are received via antenna 1317 and immediately amplified by a low noise amplifier (LNA) 1337. A down-converter 1339 lowers the carrier frequency while the demodulator 1341 strips away the RF leaving only a digital bit stream. The signal then goes through the equalizer 1325 and is processed by the DSP 1305. A Digital to Analog Converter (DAC) 1343 converts the signal and the resulting output is transmitted to the user through the speaker 1345, all under control of a Main Control Unit (MCU) 1303—which can be implemented as a Central Processing Unit (CPU) (not shown).
The MCU 1303 receives various signals including input signals from the keyboard 1347. The keyboard 1347 and/or the MCU 1303 in combination with other user input components (e.g., the microphone 1311) comprise a user interface circuitry for managing user input. The MCU 1303 runs a user interface software to facilitate user control of at least some functions of the mobile station 1301 to provide information for determining a vehicle boarding score. The MCU 1303 also delivers a display command and a switch command to the display 1307 and to the speech output switching controller, respectively. Further, the MCU 1303 exchanges information with the DSP 1305 and can access an optionally incorporated SIM card 1349 and a memory 1351. In addition, the MCU 1303 executes various control functions required of the station. The DSP 1305 may, depending upon the implementation, perform any of a variety of conventional digital processing functions on the voice signals. Additionally, DSP 1305 determines the background noise level of the local environment from the signals detected by microphone 1311 and sets the gain of microphone 1311 to a level selected to compensate for the natural tendency of the user of the mobile terminal 1301.
The CODEC 1313 includes the ADC 1323 and DAC 1343. The memory 1351 stores various data including call incoming tone data and is capable of storing other data including music data received via, e.g., the global Internet. The software module could reside in RAM memory, flash memory, registers, or any other form of writable computer-readable storage medium known in the art including non-transitory computer-readable storage medium. For example, the memory device 1351 may be, but not limited to, a single memory, CD, DVD, ROM, RAM, EEPROM, optical storage, or any other non-volatile or non-transitory storage medium capable of storing digital data.
An optionally incorporated SIM card 1349 carries, for instance, important information, such as the cellular phone number, the carrier supplying service, subscription details, and security information. The SIM card 1349 serves primarily to identify the mobile terminal 1301 on a radio network. The SIM card 1349 also contains a memory for storing a personal telephone number registry, text messages, and user specific mobile station settings.
