判定信号交叉口信号配时方案设计是否合理的重要依据是进行延误分析与定量计算。美国 HCM2000延误算法是国际上很经典的一种延误计算模型，但因不同地域交通条件的变化，在不同地域应用时延误计算结果与实测值会有不同程度的误差。采用点样本法在对哈尔滨市部分信号交叉口进行延误调查的基础上，应用 HCM2000算法对所调查各交叉口进行延误计算，通过将延误理论计算值与实测值比较分析发现HCM2000算法与实测值有较大差异。而后文中基于建立与哈尔滨市交通情况相适应的延误计算模型的思想，使用SPSS软件建立 HCM2000算法延误计算修正模型，为哈尔滨市信号交叉口控制研究和道路系统的分析评价中延误的分析与计算提供一种适用的延误计算模型。%Delay is the critical index used for evaluating the signal timing plan of intersection .The present USA HCM2000’s model is a very traditional delay model .Because of the changes of different regional traffic conditions ,the delay in different regional application will have different errors on calculation results and the measured values .The HCM2000’s model is verified with the delay data obtained through using Point Samples delay algorithms and surveyed in some intersections in Harbin .The result shows that there is a large disparity between the HCM2000’s models and the measured data .Thereby ,the HCM2000’s modified model is established with the measured data by SPSS software for calculating the delay of intersection w hich operates in different status .T he test values satisfy the Harbin’s traffic condition .All studies provide a suitable delay model for evaluating the traffic situations of signal‐controlled intersection in Harbin .
