    Study Notes

    Traffic Incident Management

    • The New Lenox Fire Protection District established a Traffic Incident Management (TIM) program for roadway incidents.
    • The TIM program incorporates the Manual on Uniform Traffic Control Devices (MUTCD).
    • The program also focuses on vehicle placement, establishing a temporary traffic control zone, personnel responsibilities, emergency vehicle lighting, proper use of PPE and other safety considerations.
    • The program classifies traffic incidents into three categories: major, intermediate and minor.
    • Major traffic incidents involve hazardous materials, fatal accidents, multiple vehicles, or natural disasters; these incidents require road closures exceeding 2 hours.
    • Intermediate traffic incidents lasting 30 minutes to 2 hours, often need lane closures and diversions.
    • Minor incidents, including disabled vehicles or minor crashes, cause lane closures less than 30 minutes; these events are typically handled by law enforcement, towing companies, and highway service patrols.
    • The TIM program promotes effective interagency collaboration between highway and public safety agencies in emergency response.
    • The program prioritizes the safe removal of blocked roadways and provides guidelines for traffic control zone (TCZ) setup using traffic control devices like cones, signage, and flares.
    • Traffic cones are deployed to channel traffic, separate opposing lanes, and create temporary work zones.
    • Cones are used to create a cone taper placement, starting at the rear of the blocking apparatus and extending upstream.
    • All responders must wear high-visibility safety vests and appropriate PPE when working on or near roadways.
    • The program emphasizes proper lighting and visibility at night using emergency vehicle lighting and additional scene lighting.
    • The TIM program recommends a phased approach to emergency vehicle lighting, starting with full emergency lights in the transition zone and reducing to flashers within the TTCZ for better driver visibility.

    Traffic Incident Control Zones (TCZs)

    • TCZs consist of several distinct zones:
      • Advanced Warning Area - Informs drivers of the incident.
      • Transitional Area - Redirects drivers, often using cones.
      • Buffer Space - Separates the transitional area from incident space.
      • Incident Space - Where the actual incident occurred.
      • Activity Area - Includes the incident space, buffer space, and traffic space.
      • Termination Area - Where drivers return to normal traffic flow.
    • The TIM program emphasizes that all personnel should work within the protected incident workspace and maintain safe visibility to oncoming traffic.
