【摘要】 交叉口延误是现代城市交通研究的重要课题,论文采用静止队列法分析了交叉口排队与停车延误。根据车辆通过交叉口的真实过程,运用静止队列法,以队列首尾各自向上游移动描述排队过程,在此基础上分析了一次排队和二次排队通过交叉口的排队长度与停车延误,并归纳了排队长度与停车延误的一般算式,最后仿真研究了连续多个周期各时段的排队长度及其变化,讨论了时段长度与停车延误准确度的关系,并确定了时段长度合适的取值范围。更多还原

【Abstract】 Delay at intersection is an important research for modern urban transportation.This paper studied the queuing and stop delay at intersection by method of stationary queue.The method was set forth according to the real course of cars’ crossing an intersection,which describes queuing through the head and the tail of the queue moving up individually.Queuing length and stop delays were analyzed respectively on the method for cars to pass through an intersection with once and twice queuing.The general formulas of calculating them were concluded.Eventually,the queuing length and its change was simulated at each time segment in the several continuous cycles.The relationship between the length of the time segment and accuracy of the stop delay was discussed.Furthermore,the proper range of the time segment length was defined.更多还原
