Geoinformational Approach to Assessing the Accessibility for Urban Areas

An important part of the accessibility of the urban environment is the connectivity of transport network, especially regarding to its usage via personal transport. There are many methods of quantitative analysis of this aspect. A significant part of them is based on the isochronal analysis. The article assumes that on the local scale the one of the key factors indicating a transport network connectivity is the asymmetry between forward and backward routes between pairs of points. A method of such analysis, the computational experiment, and the following statistical analysis procedure for checking this hypothesis. Performing this procedure allows us to confirm the hypothesis with statistical significance p=0.0081.The experiment presented in the article demonstrates the need to take into account the path asymmetry factor for calculating and evaluating transport accessibility. The given method can be used in optimizing public transport routes, designing traffic flows, and planning the development of the territory in urban agglomerations.
