Studying impact of on-ramp from multi-lane highways on the basis of experimental studies of traffic flows

Abstract

Lane-change manoeuvres are the main sources of traffic hindrance in multi-lane highways, so solving the issues of traffic capacity provision in such sections of highways should be performed with consideration of traffic flows interaction patterns. The analysis carried out in this area indicates lack of attention towards the issues of traffic capacity estimation in sections of highways adjacent to on-ramps. The article contains the results of experimental studies of the patterns of DLC manoeuvres on highways in sections adjacent to on-ramps, which provides the basis for elaboration of the methods of estimating the vehicle density impact on traffic capacity of adjacent sections of highways. The results of the studies are recommended to be applied in the course of highways design and their multi-level interchanges.
