基于“窄马路密路网”布局理念的路网容量研究

Study of Road Network Capacity Considering the Layout Concept of Narrow Roads and Dense Road Network

以“窄马路、密路网”“开放式街区”布局理念下的路网容量为研究对象,分别得出了路网容量4个因子的计算模型,从交通组织方式、道路横断面形式、路网供给与需求匹配度等3方面修正,得到更适合窄路密网布局理念的路网容量模型.

The concepts of“narrow roads,dense road networks”and“open street blocks”have been proposed in response to social problems such as traffic congestion and traffic safety caused by the traditional road networks.This paper takes the road network capacity under the layout concept of“narrow roads,dense road network”and“open block”as the research object,and derives the calculation models of the four factors of road network capacity.The three aspects of road network supply and demand matching degree were revised to obtain a road network capacity model that is more suitable for the layout concept of narrow road dense network.It provides more accurate decision support for transportation planning,policy development and traffic management.The three aspects include traffic organization mode,roadway cross section type,road network supply and demand matching degree.This paper finds that the calculation model is more suitable for narrow roads,and dense road network.
