An analysis of traffic flow distribution on roads

Abstract Traffic intensity is the main parameter determining the road category and all other road design and construction requirements. The aim of this article is to study patterns of traffic intensity on the example of a local highway Egorovshchina – Ryazanovshchina in Irkutsk region. The article presents results of traffic intensity measurements by hours and calculation of reduced traffic intensity taking into account the traffic flow depending on the number of axles and load capacity. Diagrams of the hourly dependence of traffic intensity and traffic flow distribution were created taking into account the traffic flow mix. Traffic intensity reduced to a passenger car was calculated. The research result is patterns of traffic intensity distribution by the traffic flow mix required for calculating reduced traffic intensity.
