Modelling of natural development of interurban network of vehicular roads

Abstract

The main peculiarities of transport network functioning and structure are the result of reciprocal influence of the network and its service area. Namely, current transport needs of the area are the key factor, affecting any specific decision on creating a new network element. However, transport needs of the area significantly changes in the course of time and certain management decisions are poorly coordinated and made in conditions of incomplete information on future network state. Therefore, transport networks have a variety of features of natural objects and their development can be regarded as a result of implementation of some in-ner consistent patterns and mechanisms. The models of natural development of transport networks influenced by various external and internal factors are dealt with in the article. An approach to modelling of natural development of a transport network based on information on spatial location of its peaks is suggested. As an illustration of potentiality of the given approach Sverdlovsk region network of vehicular roads is used. A measure which indicates morphological similarity of the networks is introduced. The models of Sverdlovsk region vehicular road network are built for different representations of function, which characterize the extent of remoteness of one peak to the pair to other peaks. The generating network model which is sufficiently close to a real network is obtained. It is demonstrated that many fundamental features of a real network are the result of location of its peaks and for their explanation there is no need in additional social-economic and demographic information.
