摘要

A guide information generation unit (107) acquires from a storage unit (102), information on a road width and traffic signs (such as one way, width reduction, height limit, and weight limit) concerning each route contained in route guide information generated by a route guide information generation unit (106). Here, each of the acquired information pieces is correlated with the information on the traveling vehicle size acquired by the vehicle information acquisition unit (103) and a route where the vehicle can travel is selected from the route guide information generated by the route guide information generation unit (106). A position recognition unit (105) acquires map information of a predetermined range around the acquired vehicle position information from the storage unit (102) and the map information is superimposed on the selected route to be displayed on a display unit (101).
