In Japan, more users have been able to make use of traffic information service in real time as VICS (Vehicle Information and Communication System) and navigation systems have been deployed. However, navigation systems can not always guide drivers on appropriate routes using only travel time data as they are because of the problems of accuracy and quantity. Therefore, this paper proposes estimation methods of statistical traffic data for an appropriate route search in navigation system. It includes several ideas for making the statistical traffic data more accurate. This paper describes and evaluates the algorithms for the estimation.
