Modelling Better Work Zone Behaviour

Large volumes of traffic on U.S. highways are causing state and local departments of transportation (DOTs) to face an increasing challenge to reduce the impacts of work zones on traffic congestion. According to the U.S. Federal Highway Administrations (FHWA), work zones cause about 24% of non-recurring congestion and 10% of all congestion. Work zones pose a significant threat to both workers and drivers and result in about 600 deaths and 400 injuries per year. This problem is driving an increase in research activity in such areas as driver behavior and car following. A recent study acknowledged a gap in the area of erratic acceleration and deceleration in work zones and the resulting risk of rear-end collision. Two significant projects in Virginia and Florida are working to generate detailed data for more accurate and effective modeling and simulation of traffic flow in work zones. But, in order to better understand the effects that work zones have on traffic, selecting the right one to perform the analysis is important. More research is needed as driver behavior in work zones is not fully understood.
