    Study Notes

    Traffic Incident Management Overview

    • Establishes a Traffic Incident Management (TIM) program for effective response to roadway incidents.
    • Aligns with the Manual on Uniform Traffic Control Devices (MUTCD) for safety and organization.

    Traffic Control Concepts

    • Traffic Incident Management Area (TIMA): Designated area for managing traffic during incidents.
    • Various Zones Explained:
      • Advanced Warning Area: Alerts drivers to upcoming incidents.
      • Transitional Area: Redirection of traffic using channeling devices.
      • Buffer Space: Zone between transitional and incident space.
      • Incident Space: Actual location of the incident.
      • Activity Area: Combines incident space with buffer and traffic space.
      • Termination Area: Returns traffic to normal flow.

    Incident Classification

    • Major Incidents: Last longer than 2 hours; may involve hazardous materials or multiple vehicles.
    • Intermediate Incidents: Duration of 30 minutes to 2 hours.
    • Minor Incidents: Under 30 minutes, typically disabled vehicles or minor crashes, requiring quick removal from lanes.

    Traffic Control Measures

    • Adequate traffic control devices must be readily available for intermediate incidents.
    • Manual traffic control, if needed, should be conducted by qualified flaggers or law enforcement.

    Cone Deployment and Usage

    • Cones channelize and delineate traffic, must be wind-resistant or ballasted.
    • Deploy cones from the rear of blocking apparatus towards oncoming traffic for better advance warning.
    • Personnel must face traffic when placing or retrieving cones, maintaining safety at all times.

    Single vs. Multi-Lane Operations

    • For single lane roadways, place cones across both directions to stop and divert traffic safely.
    • For multi-lane roadways, establish taper patterns to guide traffic around the incident.

    Personal Protective Equipment (PPE)

    • Class II high-visibility vests mandatory for all personnel on or near roadways.
    • PPE must be worn at dispatch if incidents are anticipated on roadways.

    Warning Devices and Lighting

    • Safety Cones: Minimum height of 18 inches, retro-reflective tape required.
    • Warning Signs: 48” x 48” signs for prolonged incidents (longer than 30 minutes) in low visibility areas.
    • Flares: Used for nighttime operations to enhance visibility for motorists.

    Emergency Vehicle Lighting Protocol

    • Initial use of emergency vehicle lighting essential for safety; should be minimized once a TCZ is established.
    • Emergency vehicle lights activated throughout the TCZ; arrow sticks direct traffic around incidents.
    • Lighting should not obscure traffic visibility; focus on maintaining safety for both responders and road users.

    Final Notes

    • Emphasis on ensuring a safe work zone for personnel and motorists during roadway incidents.
    • Clear procedures and equipment availability aim to improve response efficiency and safety on the scene.
