| 摘 要： | 城市交通信号控制是城市交通管理中的主要手段和途径。提出从系统最优原则出发制定交通管理策略的观点，建立城市区域系统最优模型，并基于MATLAB软件中的遗传算法给出求解。最后，通过两个典型交通路网模拟验证最优模型的适用性和合理性，并获得控制目标交叉口绿信比、延误数以及区域交通网络总的运行时间。

| Abstract: | Urban traffic signal control is a basic method for urban traffic management. A viewpoint is proposed to establish traffic management strategy based on system optimization principle. After building an optimized model for urban regional system, some solutions are discussed with genetic algorithm. Then two typical traffic road networks are used to check the applicability and reasonability of this model. And intersection green ratio, intersection delay number and total run time of district traffic network are obtained successfully. |
