Method of intermodal accessibility graph construction

Abstract

The article presents a method for modelling an intermodal graph of accessibility of urban areas. The accessibility of the city's territories is usually understood as a zone where a person can walk or get by transport for a certain time from a given point. Accessibility assessment is fundamental in the problems of computational urbanism and is used for a variety of applied spatial indexes and estimates. At the same time, traditional methods of assessing the transport accessibility of the urban environment require the creation of models of transport systems of the studied city, which is associated with significant costs. The situation is complicated by the peculiarities of the urban environment and the need to consider the movement of different types of transport in combination with walking. The method proposed in this article uses an alternative approach to assessing the accessibility of urban areas based on the construction of an intermodal accessibility graph. This makes it possible to use this algorithm in solving applied urban problems without the need to build complex transport models.
