SYSTEM FOR GENERATING INFORMATION ON VEHICLE TRAVEL ROUTE BASED ON CORRECTION AMOUNT AND ONBOARD DEVICE

摘要

A system for generating travel route information is provided with a map data acquisition unit (4, S220), a trajectory data acquisition unit (2, S110), a correction amount calculating unit (2, S130-S190), and a travel-route-information-generating unit (4, S250). The map data acquisition unit acquires map data including the travel route, and the trajectory data acquisition unit acquires the trajectory data representing the travel trajectory when actually traveling along the traveling route. The correction amount calculating unit calculates, on the basis of the trajectory data, a correction amount in order to generate travel route information suited for vehicle travel from the map data, and the travel-route-information-generating unit generates travel route information by correcting the travel route acquired from the map data using this correction amount.
