摘要: 为了弥补传统延误模型仅研究单个交叉口的不足,搭建了关联交叉口“相位差-延误”模型,用以定量分析关联交叉口运行情况。模型基于交通稳态理论(Webster延误模型),考虑关联交叉口交通流量、配时方案、相位差、路段长度等影响因素,可以动态反映关联交叉口相位差与延误之间的关系。用具体的算例说明了公式的使用方法,对提出的关联交叉口延误模型进行验证。结果表明:与VISSIM仿真结果比较,“相位差-延误”模型较为可靠。

Abstract: In order to overcome the demerit that the traditional delay model only studied the isolated intersection, an “offset-delay” model for associated intersections was established to analyze the running condition of associated intersections quantitatively. Based on steady-state theory of traffic (Webster delay model), the proposed model considered the influential factors of the associated intersections, such as traffic volume, timing scheme, offset and link length, which could dynamically reflect the relationship between offset and delay of associated intersections. The specific case has been applied to illustrate the use of the formula and verify the proposed delay model for associated intersections. The results show that: compared with the simulation results of VISSIM software, the “offset-delay” model is more reliable.

Key words: traffic engineering, associated intersections, offset-delay, time-space coordinates, simulation
