摘　　要：在Metanet模型基础上对北京三环快速路进行建模,在Paramics微观交通仿真软件里建立一完整的三环路网平台,并提出最优控制目标。在优化方法上,对匝道调节时间进行实时编码,采用遗传算法对控制目标进行整体优化、并进行仿真,得出该算法对改善整个环形路网交通状况有比较好的效果,提高了行车速度和道路利用率。Firstly,the various types of ramp models in the third ring-road of Beijing Expressway were presented based on METANET model.Then,the third ring-road traffic network was established in the Paramics microscopic traffic simulation software.Finally,the optimal control objective was proposed.In the optimization method,the ramp metering time was real-encoded by using the genetic algorithm to optimize the whole control objectives.The result of simulation indicates that the algorithm improves the conditions of the ring road network traffic and increases the traffic speed and road utilization.
