Embodiment

[0031] Such as figure 1 As shown, a computer-based evaluation method for the transfer coverage of public transport line sites; it is characterized in that: based on the line and site information of public transport input by the user, a road network map is constructed, and then N transfers at the current site can be found. All the stations arrived; traverse these stations, use the Dijkstra algorithm to find the shortest path for each station, and determine the number of transfers between the two stations.

[0032] On the basis of the above technical solutions, the Dijkstra algorithm is as follows: Assume that each transfer node in the road network graph has a label (d t ,p t ); where, d t Indicates the shortest path length from the starting point s to the point t; p t Indicates the previous point of point t in the shortest path from s to t. The basic process of solving the shortest path algorithm from starting point s to point t is as follows:

Abstract

The invention discloses a computer-based transfer coverage rate public transport line station setting evaluation method. The method is characterized by comprising the following steps of: constructing a road network diagram based on public traffic route and station information input by a user, and then finding all stations which can be reached by N times of transfer of a current station; and traversing the stations, solving the shortest path for each station by using a Dijkstra algorithm, and determining the number of times of transfer between the two stations. According to the method, in the public transport planning and layout stage, the reasonability of line and station setting is improved, and the huge construction investment cost caused by too low line utilization rate and unnecessary line adjustment due to subsequent unreasonable planning is reduced.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a computer-based evaluation method for station setting of public transport lines for transfer coverage. Background technique [0002] With the development of domestic urbanization and motorization, in the existing urban space, the traffic supply and demand are unbalanced, and the problem of traffic congestion in many areas is becoming more and more serious. More and more traffic operators and managers are committed to the research of public transport priority policies and measures, advocating the development of public transport to solve this problem. Therefore, more cities encourage new construction or increase the scale of existing public transportation, and adjust public transportation lines, so as to induce residents to choose public transportation as a way of travel. [0003] However, since urban public transportation, especially rail transit, has huge investme...
