Tools for Transportation Infrastructure Effectiveness Assessing in Geomarketing Studies

Abstract

The paper is devoted to the urgent problem of assessing the effectiveness of infrastructure projects in the transport sphere using graph theory and graph models that allow to form the structure of economic, information and other flows, determines the movement of people, transport and goods.The aim of the work is to study the models of spatial development to assess spatial competition, the effectiveness of infrastructure projects in the transportation sector and to solve geomarketing problems. The paper uses as its main hypothesis the assertion that existing models of spatial development can be complexified through the tools of graph theory.The main task is to assess the effectiveness of infrastructure projects in the transportation sphere using graph theory, which allows to identify promising areas of strategic planning for the location of business projects.It is shown that for further in-depth analysis of transport infrastructure sustainability it is necessary to analyze the connectivity of clusters within the graph with the allocation of bridges.The variants of building a graph model of location and solving analytical problems on its basis rationally using the tools of network and osmnx libraries of python language are shown. An approach to assessing the efficiency of infrastructure projects in the transportation sphere using graph theory is proposed.The analysis of road graphs allows to determine the optimal routes, intersection points, nodes and highways affecting the efficiency of the entire transport system of the city, which allows to forecast demand in different directions, to determine the most loaded and congested areas, as well as to identify weak links in the transport network.
