摘　　要：城市错位交叉口是一种特殊的平面交叉口,它的运行状态直接影响到干道甚至整个区域的交通运行质量。在对城市错位交叉口的一般形式及特征分析的基础上,提出了3种可行的交通组织方案及相应的信号控制方案。并以郑州市金水路中段错位交叉口为例,通过Vissim仿真软件对方案进行评价,得到了交叉口延误最小的推荐方案。研究结果表明,要保证城市错位交叉口的通畅性,必须根据现有的道路条件、交通环境和交通结构,进行有效的交通组织。The offset intersection is a special type of intersection, whose operation status affects the quality of traffic movements in the artery and even in the whole area. Based on the analysis of the normal form and characteristic about the offset intersection, the paper proposed three feasible program of traffic organization for the offset intersection and enhanced the traffic signal control plan of each program. With an example of an offset intersection on Jinshui Road, Zhengzhou City, this paper utilized the simulation software Vissim to evaluate three traffic organization programs and selected the program with minimal intersection delay as the optimal traffic organization of the offset intersection. The results indicate that the traffic must be well organized based on the present road conditions, traffic circumstances and traffic structure in order to ensure the smooth traffic flow in the offset intersection.
