The South Carolina Department of Transportation sponsored a study to examine the current state of the incident management industry in the US by reviewing the available published literature and by launching a nationwide survey of multiple incident management agencies. The study also evaluated the specific impact of traffic incidents on both motorists and the environment on South Carolina freeways by using traffic simulation and benefit-cost analysis.
