Abstract: To deal with the traffic congestion caused by traffic accident at the intersection, using connected-vehicle-based V2V communication technology, a cooperative vehicle control model was built based on location, speed and other information reported by connected vehicles. And the model can arrange vehicles' passing orders and moving trajectories on purpose of minimizing total traffic delay. Moreover, vehicles are allowed to utilize the reverse lane to bypass accident cars. An algorithm was worked out for solving the model based on both the decision tree algorithm and the rolling horizon optimization algorithm. Finally, a simulation platform was established to verify the validity of the model. Simulation results show that the model and the algorithm outperforms conventional traffic signal control methods, and can be used to significantly reduce the adverse impact caused by accident vehicles.
