为了弄清信号交叉口右转机动车对行人过街的影响机理,应用穿越间隙理论,分析行人穿越机动车的分布规律,并推导了行人过街时间模型公式,通过定量分析及模型算例,找出了行人过街时间的主要影响因素及其定量关系,模型精度基本满足要求,具有较高的理论和实用价值,为信号交叉口的信号设计,特别是行人专用信号相位的设置、分析和研究提供了新思路和新方法.
In order to find out the mechanism of right-turn vehicle crossing the pedestrian crossing at the signalized intersection, the paper studies the distribution rule of pedestrian crossing vehicles by using the clearance theory and deduces the pedestrian crossing time formula formula. Through quantitative analysis and model calculation, The main influential factors and their quantitative relationship of pedestrian crossing time, the model accuracy basically meet the requirements, has a high theoretical and practical value for the signal intersection signal design, especially the pedestrian signal phase setting, analysis and research provided New ideas and new methods.
