Abstract:
1. A traffic information distributing apparatus that distributes traffic information, comprising: a vehicle information receiving unit that receives vehicle information from a navigation apparatus installed in a vehicle; a current traffic information obtaining unit that obtains current traffic information which includes congested road information that indicates the presence of congestion and no-congestion road information that indicates the absence of congestion; a predicted traffic information generating unit that generates, based on the vehicle information, predicted traffic information according to the time the vehicle arrives at each road along a route to a destination, the predicted traffic information including the congested road information that indicates the presence of congestion and the no-congestion road information that indicates the absence of congestion; a predicted traffic information extracting unit that determines whether or not the predicted traffic information for a road is different from the current traffic information for the road, that extracts the predicted traffic information for the road if determined to be different from the current traffic information for the road, and that does not extract the predicted traffic information if both the predicted traffic information and the current traffic information are the no-congestion road information; and a traffic information distribution controlling unit that controls distribution of the predicted traffic information, extracted by the predicted traffic information extracting unit, to the navigation apparatus.
