Provided is an apparatus and method for automatically creating stopping rates of vehicles at signal-equipped intersections. A signal-equipped intersection to be subjected to specifying of stopping rates at signal-equipped intersections is selected from a signal-equipped-intersection information storage unit as a target intersection, a pass-through-intersection extraction that extracts a signal-equipped intersection that was passed-through just before reaching the target intersection as a pass-through intersection is conducted according to a prescribed rule, driving-history data of a probe car is classified for each of the routes that start from the pass-through intersection and pass through the target intersection, and the rate at which the probe car stopped at the target intersection is specified as a stopping rate, for each of the classified routes.
