Simulation of Crossing Traffic Flow without Traffic Light Using Modified Full Velocity Difference Model

Abstract

In this study, it is aimed to introduce such a one-dimensional traffic model to investigate two-dimensional crossing traffic flow at crossroad that without traffic light. The full velocity difference model is modified to adaptive stop by referring stopping sight distance and to solve conflict at crossroad by integrating self-organized rules. Simulation of crossing traffic flow is conducted and discussed. Results such as flow rate, individual velocity and traveling time show the crossroad without traffic light has significant impact on traffic flow. It is hoped this work may provide valuable evacuation references for the emergency department and individual evacuees.
