Site Selection Method for Urban External Highway Passenger Transport Hub Based on POI Data and Dijkstra Algorithm

Abstract

The invention discloses a site selection method for urban external highway passenger transport hub based on POI data and Dijkstra algorithm, comprising the following steps: establishing a site selection model for urban external highway passenger transport hub; using Dijkstra algorithm, taking the effective distance between urban road network nodes as an element, constructing The effective distance structure matrix of the road network is used to obtain the shortest travel path of passengers and buses in the urban road network, and then to obtain the set of all road sections that the shortest travel path of passengers and buses passes through; the weighted random number method is used to determine whether the passenger car chooses a certain distance. The weight of traveling at a high-speed entrance and exit, simulate the number of passengers traveling at a certain high-speed entrance and exit, solve the model, and select the passenger transport hub coordinates corresponding to the minimum value of the location model as the location of the city's external highway passenger transport hub. The method for selecting the location of the passenger transport hub in the present invention has important reference significance for alleviating the traffic pressure inside the city, ensuring the efficient operation of the urban road network system, and improving the efficiency of the city's external traffic.

Description

technical field [0001] The invention belongs to the technical field of urban traffic planning, and relates to a site selection method for urban external highway passenger transport hubs based on POI data and Dijkstra algorithm. Background technique [0002] According to the different functions of the hub, urban passenger transport hubs can be divided into urban internal transport hubs and urban external transport hubs. The city's external highway passenger transport hub is an important part of the city's overall planning and layout. It is a functional body that realizes the effective connection between the city's internal traffic and external traffic, realizes the conversion of different passenger transport modes, and ensures the continuity of passenger transport. The main function of the external highway passenger transport hub is to organize passenger transport, mainly serving intercity medium and long-distance passenger transport. Whether the location of the highway pass...

Problems solved by technology

The traditional gravity method inevitably locates the location of the hub in the central area of ​​the city. However, the central area of ​​the city is limited by factors such as urban space and public road resources, making the layout of the gravity method gradually unable to adapt to the traffic situation of large cities; Applied methods such as AHP still focus on the selection of subjective factors, and the objectivity of the method needs to be improved
