文章以广州市的江南大道与昌岗路的十字交叉口为例,在现状调查分析的基础上,进行Webster法配时的优化,并提出一套基于Paramics仿真平台的交通信号控制方案评价框架,根据所提出的框架设计了仿真实验来比较各种OD需求水平下优化方案实施的效果。实验结果表明,可以有效、便捷地对交通信号控制方案进行定量评价;优化方案的实施效果通过仿真平台可以清楚、生动的显示。 Taking the crossroads of Jiangnan Avenue and Changgang Road in Guangzhou as an example, this paper optimizes the Webster method on the basis of investigation and analysis of current situation and proposes a set of evaluation framework of traffic signal control scheme based on Paramics simulation platform. According to the proposed framework, a simulation experiment is designed to compare the effect of optimization schemes under various OD requirements. The experimental results show that the traffic signal control scheme can be quantitatively evaluated effectively and conveniently. The implementation effect of the optimization scheme can be clearly and vividly displayed through the simulation platform.
