Incident Management in Work Zones

Traffic capacity and shoulder/pullout areas are often restricted in work zones. Prompt detection and clearance of traffic incidents in work zones can help reduce secondary crashes and delay. Preparing a work zone traffic incident management plan and using strategies that improve detection, verification, response, and clearance of crashes, mechanical failures, and other incidents in work zones and on detour routes can benefit safety and mobility.
