摘要
以提高拓宽进口道车辆的运行效率,减少进口道延误为目标,分析了交叉口进口道拓宽段车辆的运行特性,并运用Vissim仿真软件对不同长度的拓宽段进行仿真分析。交叉口进口道左转拓宽段的长度不仅与左转车量的排队长度有关,而且与其相邻车道的排队长度有关;根据仿真结果得出了拓宽左转车道长度与进口道延误之间的关系。
In order to improve travel efficiency of vehicle in widened section and reduce delay, a simulation analysis for different lengths of widened section based on VISSIM was made as well as the analysis of travel characteristics of vehicle in widened section. The widened length of left-turn lane is not only related with the queue length of the lane itself, but also with the queue length of its adjacent lane. According to the result of simulation, the relationship between widened length of left-turn lane and delay can be proved.
