摘要： A route search device includes a memory and a processor. The processor performs search processing for a route from a current position to a destination of a ride-sharing vehicle based on data stored in the memory. A standard route with the shortest requested time from the current position to the destination is calculated in the search processing. A high-frequency route with a frequency of encountering a pedestrian between the current position and the destination that is higher than the standard route is also calculated in the search processing. A recognition level is compared with a reference level in the search processing. When the recognition level is equal to or less than the reference level, the standard route is selected as a final route. When the recognition level is higher than the reference level, the high-frequency route is selected as the final route.

摘要： A traveling trajectory estimation system obtains traveling record information indicating a past traveling record of a vehicle, and characteristic object position information indicating the installation position of a characteristic object, and performs a vehicle position estimation process to estimate an object vehicle position at an object time, based on the traveling record information and the characteristic object position information. In the vehicle position estimation process, not only a time previous to the object time, but also a time subsequent to the object time, is used as a reference time. The traveling trajectory estimation system sets each of a plurality of successive times as the object time, and performs the vehicle position estimation process, to estimate the object vehicle positions at the respective times, and determines a collection of the estimated object vehicle positions as a traveling trajectory of the vehicle.
