TRAVEL ROUTE INFORMATION GENERATION DEVICE

摘要

According to the present invention, a server acquires position information data showing the path traveled by a vehicle in a discrete position, and direction information data showing the traveling direction of the vehicle in the same position (S101). Based on off-route position information data showing a travel path alternative to the travel route included in the map data, information of a new travel route not included in the map data is generated (S103-S107). Based on the off-route position information data and the direction information data showing the traveling direction of the corresponding vehicle, a partial travel route showing part of the new travel route is estimated (S106). The shape of the new travel route is estimated based on the specified partial travel route (S107).
