Influence of automobilization level on traffic flow parameters

Abstract

The issues of the influence of automobilization level on traffic flow parameters are considered in the paper. The topic of the paper is relevant as a result of aggravated traffic problems in large cities in the world and Ukraine in particular. Problems are caused by the lack of correspondence between amount of transport vehicles and traffic capacity of transport network elements. The influence of the automobilization level on traffic characteristics was analyzed by many researchers. A somewhat different approach to estimating the automobilization level and assessing its influence on parameters of traffic flows was proposed in the paper. The level of automobilization was suggested to estimate depending on the purchasing power of population and its number in city districts. The level of automobilization and traffic volume in the network are connected by growth coefficients. The growth of the automobilization level leads to the increase of growth coefficients and the number of correspondences in the city transport network respectively. The modeling of transport network load allows the analysis of traffic flow parameters and their correlation with the automobilization level. The correlation of the automobilization level and traffic flow parameters is set for every type of streets and roads separately. The analyzed parameters include traffic load coefficient, traffic capacity reserves, transport operations. Knowing the mechanism of the automobilization level influence on traffic flow parameters allows planning measures for improving city transport networks and reducing negative effects of automobilization in social, economical and environmental aspects.
