为确保在信号控制平面交叉口红绿灯转换时过街行人的安全,通过分析车辆与行人的通视要求以及汽车的动力特性,在建立了通视三角形比例模型和汽车加减速运动模型的基础上,提出了阶梯型停车线合理布置形式,并计算得出了行车道前停车线与人行横道线边缘的最小安全距离指标,研究成果对城市信号控制平面交叉口阶梯型停车线的合理布置具有一定的参考价值。
In order to ensure the safety of pedestrians crossing the traffic lights at the intersection of signal control plane and crossing, the paper analyzes the requirements of vehicles and pedestrians and the dynamic characteristics of vehicles. On the basis of setting up the model of traffic triangle and acceleration and deceleration of cars, The reasonable layout of ladder-type parking line is calculated and the minimum safety distance index of the parking line before the roadway and the edge of the pedestrian crossing line is calculated. The research results have certain reference value to the reasonable arrangement of the ladder-type parking line at the urban signal control plane intersection .
