基于VISSIM仿真的交叉口间接左转适应性研究

为了在保障行车安全的前提下,提高交叉口间接左转的运行效率,分析了间接左转的设置条件,定义了典型应用环境,并将规划方法放入典型应用环境中采用微观仿真软件进行评价。结合我国的交通结构特征进行了组织设计的优化,提出了结合路中式公交专用道设置间接左转的组织方式和右转机动车与自行车在近交叉口段转换车道功能的组织方式。

Study of the Adaptability of Indirect Left-turning at the Intersection Based on VISSIM Simulation

Intersection has the greatest impact on road capacity and safety.Therefore,it has great significance to organize the left-turn traffic at crossroads.Many cities both in abroad and domestic have put the method into practice,but it is necessary to study the efficiency of the method in a typical application environment.In order to improve the efficiency of Indirect Left-Turning followed by right-turn also based on ensuring the running safety of vehicles,we analyzed its application conditions and defined its typical application environment.In typical application environment,micro simulation software will be introduced to evaluate new method.At last the paper improved the organize method by considering the traffic construct domestic.Organizing the Indirect Left-Turning by combing the bus lane which in the middle of the road or changing the function of right-turn lane and cycle-track in the section approaching the crossing.
