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.
