Outline of Final Research Achievements

In this study, it is confirmed that link travel time distributions are different according to the direction of next link (i.e. go straight, turn right or left) , and it is valuable to record the probe vehicle data of each lane. We proposed a method to predict a link travel time by using a historical data, which is modified a particle filtering model, and confirmed its effectiveness. In order to predict a link travel time distribution in urban area, it is necessary to do traffic flow simulation. Therefore, we improved the conventional stochastic cell transmission model for the network consisting of signalized intersections.
