NATIONAL TRAFFIC INCIDENT MANAGEMENT
TIM COMPREHENSIVE EXAM ALL QUESTIONS
AND ANSWERS SURE A+
✔✔Traffic Management - ✔✔he appropriate use of traffic control devices to establish a
Traffic Incident Management Area reduces the likelihood of secondary crashes
✔✔Advance Warning Area - ✔✔• Established upstream of the incident to alert drivers of
the upcoming incident scene
- Should also be upstream of any traffic queues so that warning is given to road users
before encountering stopped traffic
• Should be high priority for emergency responders
• A shoulder taper, set up using traffic cones, may also be established in the Advance
Warning Area
✔✔Back of Queue Management - ✔✔• A responder vehicle strategically placed on the
shoulder upstream of an incident with its emergency lights activated can help slow
motorists approaching an incident scene
- This role is typically filled by law enforcement or a Safety Service Patrol
, ✔✔Additional or earlier advance warning may be necessary due to - ✔✔limited sight
distances created by roadway geometry
- Hills
Curves
- Bridges
- Intersections
✔✔Additional advance warning may also be necessary during - ✔✔adverse conditions,
such as rain, snow, ice, smoke, fog, darkness, etc.
- Wet roads double the average motorist stopping distance over that for dry road
conditions
- Poor visibility can lengthen driver reaction time
- Increases responder's degree of risk
✔✔Transition Area and Tapers - ✔✔Section of roadway where drivers are redirected
out of their normal path
•usually involve the strategic use of tapers
- Tapers can be set up using cones or flares
• No vehicles should be positioned within the tapered portion of the closed lane
✔✔Upstream (Longitudinal)
Buffer Space - ✔✔• Separates the Transition Area from the Incident Space
• No vehicles should be positioned
• Provides recovery area for errant vehicles
• Speed of passing traffic and sight distance should be
considered when determining the length of the buffer
space
✔✔Flaggers - ✔✔should use clear and distinct hand signals and
must wear high-visibility safety apparel
• should stand either on the shoulder or in the
closed lane prior to stopping road users
• should be stationed sufficiently in advance of
the responders to warn them of approaching danger
• should stand alone, away from other
responders, vehicles, or equipment
