Impact of road traffic accidents on the dynamics of traffic flows

Abstract

Traffic flows can be affected by any changes on the road. Particularly large changes can be caused by traffic accident. Using the discrete traffic flow method, the dynamics of intensive traffic flow on the road was analyzed. As a research object chosen one of intensive road in Vilnius city. There are eight traffic lights in the intensive road, with a 120 s period cycle. On this road, one traffic accident is simulated on a certain road section, which occur at same times, but different traffic accident elimination time. The changes in traffic flow parameters are obtained at different traffic accidents, which almost completely stops the traffic flow, and their removal times. The results of the research are presented as the parameters changes in traffic flow in time and characteristic waypoints. The dynamics of traffic flows is investigated, after eliminating the consequences of the traffic accidents. Setting the time at which the traffic flows up to the start of traffic accidents.
