| 摘 要： | 在交通分配的研究中,车辆在路段上的行驶费用是决定网络交通流分布的关键因素之一。论文面对动态交通分配建模需要,在网络饱和条件下,对车辆在路段上的行驶时间进行了分析和建模。详细讨论了饱和交通网络中考虑容量约束下的车辆连续行驶时间和路口延误时间,在排队延迟模型中考虑了车辆的实际长度及由此而带来的影响,建立了离散的函数模型。最后给出计算实例,对比了点排队和实际排队的不同。

| Abstract: | Travel time is the major factor which controls users' route choices.In this paper,the link travel time experienced by vehicles in saturated network is dealt with two components:the uncongested cruise time over the link and the queuing delay.The first-in-first-out discipline and capacity constraint are taken into account.The physical lengths of queues are considered.Finally,a discrete link travel time function is proposed and typical differences between point and physical queue analyses are presented through an example calculation. |
