Abstract: In one embodiment, a method includes: receiving historical data of a plurality of vehicles that traveled in an area, the historical data including a sequence of location data points and a sequence of motion-data points for each vehicle in the plurality of vehicles; determining, for each vehicle, a motion-data trace of a path traveled by that vehicle in the area based on the sequence of motion-data points associated with that vehicle; generating, for each vehicle, an estimated path traveled by that vehicle based on the sequence of location data points and the motion-data trace of the path associated with that vehicle; generating an average path traveled by the plurality of vehicles based on the estimated paths traveled by the plurality of vehicles; and providing the average path to a device associated with a driver of a subject vehicle traveling in the area to assist with navigation.

Abstract: The present application discloses an improved transportation matching system, and corresponding methods and computer-readable media. According to disclosed embodiments, a transportation matching system receives a session indicator and device-based location. The system utilizes the received request and device-based location to identify and analyze historical transportation matching system information. The system then generates a confidence score based on this information that indicates a level of confidence that the device-based location is a pickup location associated with the request. If the generated confidence score exceeds a predetermined threshold, the system provides display components to a requestor computing device that enable confirmation of the transportation request with a single user interaction.

Abstract: This disclosure covers methods, non-transitory computer readable media, and systems that generate route tiles reflecting both GPS locations and map-matched locations for regions along a route traveled by a client device associated with a transportation vehicle. For example, in some implementations, the disclosed systems use an artificial neural network to analyze the route tiles and determine route-accuracy metrics indicating GPS locations or map-matched locations for particular regions along the route. The disclosed systems can then use the route-accuracy metrics to facilitate transport of requestors by, for example, determining a distance of the route or a location of a client device associated with a transportation vehicle.

Abstract: In one embodiment, a method includes receiving a sequence of location points and motion data associated with a mobile computing device. The method further includes generating, based on the motion data, a motion-data trace of a path and calculating, for each location point, a distance between the location point and a point on the motion-data trace of the path. The method further includes determining that the distance associated with at least one location point exceeds a threshold distance. The method further includes generating an estimated path traveled by the mobile computing device using (1) the point on the motion-data trace of the path used for calculating the distance associated with each of the at least one location point and (2) the received location point for each of the sequence of location points whose associated distance is at or within the threshold distance.
