基于VISSIM的平面交叉口交通仿真与改善研究

Studies on Intersection Traffic Simulation and Improvement Based on VISSIM

平面交叉口是交通系统中极易发生拥堵的地方,运用先进的仿真软件VISSIM对交叉口进行改善设计具有较强的优势。文章在分析VIS-SIM仿真软件原理的基础上,提出了平面交叉口的改善方法,并以兰州市建宁路与宝石花路交叉口为例进行了交叉口改善与仿真分析。研究结论对城市平面交叉口改善设计具有一定的借鉴意义。

The intersection is the location apt to congestion in the transportation system,and the use of state-of-the-art simulation software VISSIM has the strong advantage in the improvement design of intersections.On the basis of analyzing the principles of VISSIM simulation software,the article proposed the improvement method of intersections,and with the intersection of Jianning Road and Baoshihua Road in Lanzhou City as the case,the article conducted the improvement and simulation analysis.Research findings have a certain referential significance for the improvement design of urban intersections.
