摘要
针对高速公路交通管控措施的评价问题,提出基于交通仿真软件的评价方法。交通仿真技术克服了传统方法的局限,为高速公路的管制研究提供了一种新的、高效便利的研究手段。对高速公路常用的交通管制策略进行分析,提出高速公路的交通仿真模型。最后以广清高速公路为例,通过VISSIM对实施交通管制手段的高速公路交通流进行模拟仿真,建立微观交通仿真模型,考察了交通管制措施的实施效果,从而为优选出最优的交通管控策略提供科学合理的依据。
Considering the evaluation problems in expressway traffic control strategies,an evaluation method based on traffic simulation software is proposed.Traffic simulation technology overcomes the limitations of traditional methods,and provides an efficient and convenient research method to the study of expressway control.Analyzing the commonly used expressway traffic control strategies,traffic simulation model of expressway is put forward.Finally,taking Guang-Qing Expressway as an example,a simulation model of traffic flow on the traffic controlled expressway is simulated using VISSIM,a microscopic traffic simulation model is set up.Implementation effect of traffic control is investigated.This method provides a scientific basis for selecting the optimal traffic control strategy.
