Comparison of Analysis Methods of Intersection Delay Under Singnal Control

延误是评价交叉口服务水平和车辆通行效率的一个重要指标.文中引入停车延误和控制延误的概念,分别采用现场调查法、HCM2000算法以及仿真方法对停车延误和控制延误进行了分析计算,并以武汉市小东门交叉口信号控制方案设计为例,应用VISSIM 4.10仿真软件对其延误进行了仿真计算分析,通过与点样本法、HCM2000算法的计算结果比较,表明VISSIM软件在信控交叉口延误计算分析中具有较好的精准性和有效性,可以作为交叉口延误分析评价的有效方法之一.

The traffic delay is an important index to evaluate the service levels and the operation efficiency at the signalized intersection.Based on presenting the stopped delay and control delay,this paper emphatically analyses the delay calculation of spot sample method,HCM2000 algorithm and the simulation method.Finally this paper taking the example of Wuhan Xiaodongmen intersection to calculate the intersection delay by simulation software named VISSIM 4.10.According to the comparison and analysis of VISSIM simulation with spot sample method and HCM2000 algorithm, the accuracy and analysis of VISSIM simulation with spot sample method and HCM2000 algorithm, the accuracy and effectiveness of this software in calculation of delay at signal-controlled intersection have been proved. So the VISSIM simulation method can be used as an effective way to analyze and evaluate the traffic delay at the signalized intersection.
