Study on the estimation method of travel speed for general vehicle using bus probe data

Abstract

In this study, using bus probe data, we developed the program, which can remove the influences at bus stops, in order to calculate the link travel speed of general vehicle, as the method to grasp accurate and detailed traffic situation in the urban area. Moreover, we verified the necessity to remove those influences. And we proposed estimation formula of travel speed for general vehicle using bus probe data. In addition, it became possible to grasp a more precise traffic situation by considering the roadsid situation.
