摘要
介绍了一种将路段和交叉口综合考虑的城市道路通行能力新概念——等效通行能力,并简单说明了其概念和调查方法。结合上海市多条城市道路的调查数据,就等效通行能力分析中交通流模型的选择进行了研究,得到选用Underwood模型较优的结果,并在理论上给出了相关道路的等效通行能力和自由流车速。
Firstly, a new concept of urban road capacity—— equivalent capacity was introduced, which considered both road sections and intersections. Its conception and methods of investigation were explained. Then, the choice of traffic flow model in equivalent capacity was explored based on the research data of many urban roads in Shanghai. Finally, choosing Underwood model is better, and the equivalent capacity and free speed of involved roads were presented in theory.
