| Abstract(in English) | Authors are developing a travel time estimation method that eliminates one of the weaknesses of VICS (Vehicle Information and Communication System). To determine the travel times of all possible travel toutes we need the travel time of all individual roads. Unfortunately, VICS doesn't provide the travel time for quite a few roads in Japan. VICS does, however, provide information on traffic jam data on all individual roads. This paper proposes to use the trafic jam data to estimate the travel times of the roads not covered by VICS. The proposed method first applies regression analysis to the trafic jam data of roads whose travel times are known to VICS and the travel times to determine the coefficient of transformation. Next, various road attributes (road category and restriction speed etc. of each road) are subjected to multi-regression analysis to optimize the coefficient of transformation. Finally, for roads whose travel times are not known to VICS, the proposed method applies the new coefficient of transformation. Authors conduct an experiment that confirms the method's excellent accuracy on general roads throughout the country. |
