| 摘 要： | 随着机动化和城市化的迅速发展,城市交通问题已经成为一个非常严重的社会问题,城市轨道交通系统由于其特有的优势被作为解决城市交通问题的一个很重要的手段。本文首先对影响轨道交通发车间距的因素进行了分析。在影响因素分析的基础上,分别通过以运营者效益最大化与社会福利最大化为目标函数,建立了合理发车间距的优化模型。最后,给出一个简单的算例。

| Abstract: | Urban transport problems have become severe social problems with the motorization and urbanization. Urban rail transit system has been considered as an efficient means to mitigate urban transport problems because of its advantages. Firstly, the article analyzes the influential factors of headway. Based on the analysis of these factors, an optimization model of headway is put forward with the objective function of operator profit maximization and social welfare maximization respectively. Finally, this article put forward a simple case to show how to compute a optimal headway. |
