A Decision Model for Justifying the Benefits of Detour Operation Under Non-recurrent Congestion

This paper presents a detour decision model for freeway non-recurrent congestion management, based on the results of extensive simulation experiments and operational guidelines for highway agencies. The proposed model offers a reliable and effective tool for responsible traffic operators to make consistent detour decisions in response to a detected incident. Numerical results clearly indicate that a timely and well justified detour operation can yield substantial benefits to both the driving populations and the entire community.
