Abstract: Previewing and analyzing the exist models of link travel time functions, paper gives the influence factors and construct parts, that is the car running time on non congest section of link and the delay time in downriver crossover. The key and very important contribution is the calculation to the car queuing length, author constructs a method according to the wave theory of traffic flow. It is a strong basis for studying dynamic traffic assignment.

Key words: link travel time, traffic assignment, urban traffic

摘要: 在分析和评述现有路段行驶时间函数优缺点的基础上,提出了路段行驶时间由在非拥挤部分的走行时间和排队部分的走行时间2部分构成的思想,最后给出了计算非拥挤部分走行时间的关键因素,即交叉口车辆排队长度的计算方法.
