Accessibility-based urban rail transit transfer node site selection method

Abstract

The invention provides an accessibility-based urban rail transit transfer node site selection method, and belongs to the technical field of traffic. The method comprises the following steps of: determining a transfer point alternative set of urban railways and urban traffic according to urban railway planning lines and rail transit line distribution; drawing an urban traffic topological graph according to the transfer point alternative set; according to the urban traffic topological graph, calculating by utilizing an improved space syntax to obtain accessibility of alternative transfer nodes of the urban rail; and completing site selection of the urban rail transit transfer nodes according to the accessibility of the urban rail alternative transfer nodes. According to the method, the accessibility of the alternative transfer stations is calculated and compared to obtain the urban railway and urban internal rail transit transfer station selection scheme, so that the problem that the rail transit node accessibility obtained by the traditional space syntax only considers the transfer times between the stations is solved; and the influence of the number of stations on the connecting line of each point is neglected.

Description

technical field [0001] The invention belongs to the technical field of transportation, and in particular relates to an accessibility-based method for site selection of urban rail transit transfer nodes. Background technique [0002] Urban railways mainly serve commuting, schooling and business passenger flows between cities and suburbs, central cities and satellite cities, and key towns. The connection of urban rail transit such as subways and trams, the travel process of commuters from the periphery of the city to the center of the city is as follows: figure 1 , when there are two or more connection points between urban rail transit and urban rail transit, the selection of transfer nodes will affect the travel time of passengers by affecting the travel route of passengers. Willingness to choose urban railways. When selecting transfer stations between urban railways and urban rails, the convenience of transfer stations to all other stations on urban rails should be ensured...

Problems solved by technology

[0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a site selection method for urban rail transit transfer nodes based on accessibility, which solves the problem that the accessibility of rail transit nodes obtained by traditional space syntax only considers the location between stations. The number of transfers, while ignoring the problem of the number of stations on the connecting line of each point
