PROBLEM TO BE SOLVED: To quickly provide a user with a reference speed passing through a traffic light, whereby the user can drive according to the speed and improve the passing efficiency. SOLUTION: A step 201 of acquiring a signal to be passed adjacent to a user's geographical position in a predetermined through band of a navigation route, and a current time in the current instruction signal switching cycle of the signal to be passed. Step 202 to obtain the time length from to to the end time of the passage instruction signal and obtain the remaining time available for passage, and the user passes through the signal to be passed at a predetermined threshold speed within the remaining time. It includes step 203 for predicting whether or not it can be done, and step 204 for determining the threshold speed as the navigation speed and obtaining navigation information if it can pass.
