摘要
针对远引掉头点的选址较为模糊,多以实际整改的感性经验为主,没有形成系统的理论规划方法的情况,利用微观仿真软件VISSIM对远引掉头的各种常见的掉头位置进行了交通仿真.采用车辆的平均延误作为评价指标,建立了各组织方式下交通流量与车辆平均延误的关系曲线,选出在不同的交通状况下的最佳组织方案.
The current U - turn location selection is usually ill - defined, experiential and short of systemic programming theory. To overcome these shortcomings, the microscopic traffic simulation software VISSIM is adopted to make simulation of the different accustomed location of U - turn traffic managements at intersection. The average delay is used as estimation parameter. The average delay - volume curve of every traffic managements is then established based on traffic simulation. An optimal plan is therefore put forward in different traffic conditions.
