Traffic signal control model based on queue management in high-density network
控制排队长度的高密度路网信号优化模型

To improve the traffic management in a high-density network, we propose a distributed traffic signal control model to manage the queues in the intersections, based on the characteristics of high-density network. This model minimizes the average travel delay and the average queue ratio under the constraints on the queue dissipation and the signal control parameters. In addition, to avoid queue spillbacks, a high-priority queue spillback constraint is built. Simulation results illustrate the improvement of the traffic travel efficiency in high-density networks, and the effective avoidance of queue spillbacks.
