Study on Vehicle Delay Based on the Vehicle Arriving Distribution at Entrance Lanes of Intersection

Through analyzing vehicle arrival distribution at entrance lanes of signalized intersection, established the vehicle arrival distribution model, and then combined with the arrival distribution model, presented delay model of signalized intersection entrance lanes. In order to ensure the accuracy of the delay model, the arrival time of the vehicle was divided into different periods, and then we can get more accurate vehicle delay of different arriving periods. Finally, using partial data from urban signalized intersection, made a simulation for validating the validity of model. The result shows that there are small deviation between simulation and model calculation. Therefore, the Research results can provide the reference for coordinate control of adjacent intersections and signal control parameters optimization of target intersection.
