【摘要】 从行程时间延误的范畴,分析了城市信号交叉口车辆的受阻过程、延误分类和确定方法,并针对停车延误的点样本调查方法,在实际教学科研实践过程的基础上,提出了改进方法,将停车统计由时刻统计改为时段统计。结合桂林实例交叉口的延误调查的调查结果、间断航空摄影法实测结果和韦伯斯特模型数值计算值,分析给出了点样本法和改进方法的适用条件。更多还原

【Abstract】 Based on travel time delay category, the process of vehicle travel at signal intersection, delay sorts and the method to obtain the delay are described And improved method is presented for the Individual Sample Stop Delay survey method, which is brought out from the practice of the teaching and scientific research Moment statistic for stop count is replaced with period of time in the improved method Based on example signal intersection survey result, road test result by the discontinuous photography, and the mathematics calculated result by Webster model, the application condition of the Individual Stop Delay survey method and the improved method are gave out in the paper更多还原
