Studying the transport accessibility of mining areas in a city with a linear dispersed urban planning structure

Abstract

The study focuses on a significant scientific and practical issue, specifically the analysis of transport accessibility in isolated mining areas within a city characterized by a linear dispersed urban planning structure. The approach to this analysis is based on transport modeling using the PTV Visum software. The transport system of a city with a linearly dispersed structure was modeled using Kryvyi Rih as a case study. From the 237 transport zones in Kryvyi Rih’s transport model, five zones were identified where employment in the open pit mining industry exceeds 7,000 jobs. These zones were selected for further analysis as the city's key mining areas. The accessibility of these mining areas from other parts of the city, accounting for the potential use of private vehicles, was evaluated using the travel time criterion under conditions of a loaded transport network. It has been demonstrated that the linear layout of the city restricts access to remote mining areas for the working-age population. The author identifies critical bottlenecks in the city’s street and road network, which negatively impact the accessibility of these mining areas. A comparison of individual transport correspondence diagrams from various city zones to the mining areas, alongside accessibility isochrones, revealed that the ten highest-volume correspondences originate from zones situated within a 30-minute driving distance to the mining areas. It is noteworthy that these transport correspondences frequently originate from non-adjacent zones. Consequently, the study’s findings allow for the consideration of urban planning and spatial development in future measures to optimize the functioning of the city’s transport system, with a focus on improving accessibility.
