Abstract:

In order to describe the travel time of signal-controlled roads, a travel time model for urban basic roads based on the cumulative curve is proposed. First, the traffic wave method is used to analyze the formation and dispersion of the vehicle queue. Cumulative curves for road entrances and exits are established. Based on the cumulative curves, the travel time of the one-lane road under stable flow input is derived. And then, the multi-lane road is decomposed into a series of single-lane links based on its topological characteristics. Hence, the travel time function for the basic road is obtained. The travel time is a function of road length, flow and control parameters. Numerical analyses show that the travel time depends on the supply-demand condition, and it has high sensitivity during peak hours.

为了描述信号控制路段的行程时间, 基于累计曲线法提出了城市基本道路的行程时间模型.首先利用交通波方法分析了路段排队形成及消散过程;然后构建路段入口和出口的累计曲线, 通过累计曲线得到了单车道、稳定流量输入条件下的形成时间函数;最后考虑路段的拓扑结构特性, 将多车道路段分解成多个单车道的组合, 并得出了基本道路的行程时间模型.该行程时间函数是路段长度、流量以及信号控制参数的函数.数值分析显示, 行程时间取决于路段交通供给-需求情况, 且在高峰情况下更加敏感.
