| 摘 要： | 针对复杂的城市交通信号控制系统,基于车流与流体的相似性,将交通路网抽象成双向管网模型,并采用流体动力学理论对网络内车流进行描述.基于相邻路口之间车流信息的共享,通过对N-S方程的数学重构,建立了各路口车流基于相位的自组织控制规则.仿真实验结果表明:自组织控制规则不仅实现了交通网络中的车流量平衡,而且系统的控制性能得到了明显的提高.

| Abstract: | Aiming at the control system of urban traffic signals with complexity characteristics,based on the analogy between traffic flow and general flow,the traffic network was abstracted as a pipe network system.The flow in traffic network was described by hydrodynamic theory.Based on the information share between adjacent intersections,through the mathematical reconfiguration of N-S equation of flow,the phase based self-organizing control rules of intersections was built to implement the flow equilibrium in urban traffic network.The results show that the control performance of traffic system is improved by the above approach. |
