从集计角度分析了运行多种交通方式的城市交通系统。利用目前已受关注的宏观基本图(简称MFD),描述城市交通的整体特性。以旧金山某区为例,使用现有数据,通过仿真论证如何应用MFD监管真实交通网络。然后讨论了同一路网中不同交通方式间如何相互作用,以及如何将这些作用纳入包含多种交通方式路网的MFD。研究得到的两个主要结论是:1)证实了已有研究猜想——对市区拥挤区域限行,可提高包括被限行者在内的所有出行者的机动性;2)为公交方式提供专用道路空间可提高所有交通方式的可达性。
From the point of view of collecting and collecting, it analyzes the urban traffic system that runs multiple modes of transportation. Using the macroscopic basic map (MFD) which has been paid attention to at present, this paper describes the overall characteristics of urban traffic. Take a district in San Francisco as an example, use existing data to prove how to use MFD to monitor real traffic network through simulation. It then discusses how different modes of transport interact on the same road network and how they can be incorporated into an MFD that includes multiple modes of transport. The two main findings of the study are: 1) Confirming that the conjecture of the existing research - restricting the crowded area in the urban area can improve the mobility of all the travelers including the limited-entrants; and 2) provide a dedicated road for public transport Space can improve the accessibility of all modes of transport.
