ABSTRACT
Freeway work zones result in congestion and traffic delays leading to increased driver frustration, increased traffic accidents, and increased road user delay cost. The traffic
delay costs to users have been mathematically modeled and evaluated based on
simplifying assumptions. Since the freeway work zone segment length has a significant
impact on both the agency and user costs, efforts have been made to find the optimum
freeway work zone segment length so as to minimize the costs to users and freeway
agencies.
