When alternative incident management strategies are evaluated, there is often a need to convert reductions in incident clearance time to a monetary cost saving. In the past, the Virginia Department of Transportation (VDOT) has used unit delay costs from other agencies to estimate incident congestion costs and the benefit of incident management programs. To...
