Abstract
Signal data stored in an information storage unit of an on-board vehicle navigation device includes signal numbers, position information for each signal, signal indication information for determining the indication, and information for a relationship between the indications and times for each signal. Based on a determination that the target signal has been set by selecting a signal intersection on a map screen (S), a route from a current position to the target signal is searched (S). Signals on the set route are read from map data (S). Travel time between the current position and the closest signal on the route and the travel times required between adjacent signals on the route are calculated (S). The indication information for each signal is predicted from the travel times required and the signal indication information in the signal data (S). And then, the indication of the target signal at the time of arrival is determined and announced (S).
