Abstract
Timely detection of traffic incidents largely determines the traffic management algorithms‘ effectiveness. To date, an accurate method for detecting road incidents has not been developed. As a result, different approaches to determine the incidents‘ duration are used. This paper observers currently available approaches to identifying road incidents and suggests dividing incidents into four stages: detection time, reaction time, clearance time and recovery time. Determining the impact degree of various factors on the incident duration is important for designing an efficient traffic management algorithm under incident conditions. Four-stage split can be used for developing an algorithm minimizing the incident duration as well as the time needed for road traffic recovering. The article presents the results of traffic flows‘ modelling, which makes it possible to estimate the road incidents‘ detection time as well.
