城市轨道交通新线接入对既有网络 客流分布的影响

以城市轨道交通新线接入对既有网络客流影响为研究对象,深入研究相关理论与方法,基于接入轨道交通网络的新线特点、接入位置等因素,提出接入轨道交通既有网络市区贯穿型线路、市区环状型线路、郊区延伸型线路3种新线类型,分析不同新线类型接入后对既有轨道交通网络客流分布的影响以及引起客流分布变化的原因,主要有:网络规模的扩张、土地使用性质的改变、网络连通性增强3个原因,并通过选取北京既有网络中的4号线为典型案例,分析不同类型的线路接入对4号线的客运量、换乘量以及断面客流量的影响,从而得出城市轨道交通新线接入对既有网络客流分布的影响机理。

Impact on Passenger Flow Distribution by New Lines Connected to the Existing Network of Urban Rail Transit

The impacts on passenger flows of the existing network by new rail lines are researched,and the related theories and methods are explored.The new lines are classified into three types,i.e.,the urban crossing lines,the urban loop lines and the suburban linked lines,and the influences of different types of lines joining the existing rail network are proposed.The expansion of urban rail transit network,the property change of the land use and the enhancement of the network connectivity are the three main factors that influence the characteristics of the passenger flows in the whole network when the new line is connected.The impacts of the new line on the network was analyzed by taking Line 4 of Beijing urban rail transit as an example,and the internal mechanism of impacts on the passenger flows,transfer flows and section flows of Line 4 were studied under different types of connection ways.
