Modeling Drivers’ En-route Diversion Behavior During Congestion: A Pilot Study

This research will focus on modeling drivers’ diversionary behavior during disruptions in coastal road networks. In recent years, climate change dramatically increased the frequency and intensity of potential disruptive events such as Floods, and sea-level rise along U.S. coastlines. Such unexpected events can trigger extensive disruptions and road closures in dense coastal regions. This situation particularly can be more drastic if it occurs during an emergency evacuation because of unbalanced demand and oversaturated routes. When faced with these cause-specific disruptions, many drivers, particularly those familiar with routine traffic patterns and alternate routes, will seek out and take advantage of alternative paths. While they may not be as efficient as their intended travel path, drivers use diversionary routing to reduce the travel time from paths that they know will be delayed. Various studies investigated the effect of this diversionary behavior during nonrecurrent events on various scales. For example, Knoop et al., (2009,2010) in a series of studies, investigated the microscopic and macroscopic impacts of incidents on drivers’ behavior and transportation network. However, little to no effort has been made to identifying behavioral influential factors and modeling the traveler’s rerouting behavior during congestion Thus, the main objective of this research study is to investigate the driver’s rerouting behavior during congestion and disruptive events in coastal communities and evaluate the spatiotemporal impact on transportation system by using trajectory data and assessment of traffic dynamic variations.
