针对左转机动车流量大、行人斜向过街需求高的 T 形交叉口，结合交叉口车流、行人流的交通特性，提出了一种左转机动车和斜向行人协同过街的思路，在交叉口内设置斜行斑马线和Z字形人行横道，以降低交叉口整体延误及人-机冲突；并建立了基于人-机冲突的交叉口平均延误模型，该模型能实现交叉口交通冲突、交通延误的合理计算；最后，选取武汉市一个典型的 T形交叉口对该方法进行了验证，利用所建模型和VISSIM仿真两种方法进行验证，结果表明，改善后的平均延误降低了34．6％．

When the T-shaped intersection having many left-turning vehicles and large demand of diago-nal pedestrians ,combined with the traffic characteristics of the vehicles and pedestrians ,a left-turning vehicles is presented and the design method of diagonal pedestrians crossing the street together ,and set diagonal lines of a zebra crossing and "Z"type pavement in the intersection .Comprehensive consid-ering the traffic conflicts and traffic delays ,the average delay model of pedestrian-vehicle conflict ,is established it puts pedestrian and vehicle as a whole to consider ,which can directly reflect the degree of con-flict ;Finally ,selecting a typical T intersection in Wuhan city for example ,through the model and VISSIM simulation verification ,the results show that the improved average delay w as reduced by 34 .6% .
