Determination of pedestrian accessibility for urban public transport stops

Introduction. This article is devoted to the problem of determining the territorial (pedestrian) accessibility of stopping points in large cities, which is one of the indicators of the quality of transport services for the population.The aim of the study is to develop a methodology for determining the territorial (pedestrian) accessibility of stopping points of a large city with a thousand or more stopping points, based on publicly available data. The cause of the study was the dificulty of solving this problem, due to the large number of both stopping points and residential facilities, the straightforwardness of the shortest pedestrian approach, the lack of detailed instructions for performing calculations, etc. Based on the review of Russian and foreign scientific sources, approaches to determining the territorial accessibility of stopping points were considered, taking into account various additional parameters, such as the number of routes passing through a stopping point, the intensity of passenger exchange, the availability of socially significant objects, etc. The existing difficulties and peculiarities in determining the availability of stopping points for individual and multi-apartment residential buildings are given. In the framework of the System-wide measures for the development of road facilities federal project and the Safe and high-quality roads national project when preparing an application for the purchase of passenger transport rolling stock for Omsk, the authors carried out scientific and practical work, as a result, a methodology has been developed to overcome some difficulties in determining the transport accessibility of stopping points in a large city by using a partially automated approach at its individual stages.Materials and methods. In particular, tools such as Yandex Map Designer, Table Excel Editor, Xtools Add-in for Excel, QGIS program, Macro in Excel using JavaScript API and HTTP geocoder were used.Results. The calculation of territorial accessibility of stopping points using the developed methodology was carried out for Omsk. The application of this technique allows to reduce labour intensity of calculations up to 10 times. Discussion. The discussion of the results presented guidelines for further improvement of the developed methodology
