To obtain a navigator which can operate accurate time necessary for running on the basis of a running velocity taking the number of lanes of a road into account, and select a route in which necessary time is the shortest.

This navigator selectively set a running route between a present spot and a destination and displays the route together with a net of roads, by storing information of every specified section of a stored net of roads and operating the time necessary for running of connection combination of the stored specified sections by a route setting means 8. A storing means 7a for the number of lanes and velocity is installed, and stores the running velocity corresponding to the number of lanes and the limiting velocity in a specified section. The above information in each section contains the number of lanes and the limiting velocity. The route setting means 8 operates the time necessary for running of connection combination of specified sections, on the basis of the running velocity corresponding to the number of lanes and the limiting velocity of the above specified section which the storing means 7a has stored. Hence a running route is selectively set.
