LEA 720 Phase 3 Questions and Answers Already Passed

LEA 720 Phase 3 Questions and Answers Already Passed What is the definition of Traffic Incident Management(TIM)? A planned and coordinated multi-disciplinary process to detect, respond to and clear traffic incidents so that traffic flow may be restored as safely and quickly as possible. What is Traffic Incident Management National Unified Goals? §Responder safety §Safe, quick clearance §Prompt, reliable, interoperable communications. What are the four compenents of a Traffic Incident Management Area (TIMA). • Advance Warning Area - Notifies upstream traffic of emergency situation ahead • Transition Area - Traffic is "transitioned" away from Activity Area • Activity Area - Buffer Space - Incident Space • Termination Area - The area at the end of the Activity Area and where traffic can return to its normal flow. Describe multiple traffic control devices that can be used to provide advanced warning. • Emergency traffic control warning and guide signs should have: - Diamond shape - Black lettering and a black border - Fluorescent pink background • PCMS can be used for intermediate incidents and are strongly recommended for use during major incidents • Tapers can be set up using cones or flares - skip lines provide a useful guide for measuring distances What is a taper in traffic control? The taper is the transition area where a driver must adjust their travel path. Tapers are also used to transition traffic back to its normal path of travel at the end of the area. How should Tapers be used? • A taper should encompass as much equipment as is available on the scene • Consider roadway speed - the higher the speed the longer the taper • Tapers should be set up to accommodate for sight obstacles • Try to maximize the spacing covered with the cones available at that time • Block as much of the roadway as needed and extend the taper out as far as possible to allow drivers adequate time to merge • Most high-speed highways in Wisconsin use a skip line distance of 50 feet from the start of one line to the start of the next (or from the end of one to the end of the next) What is the difference between upstream and downstream in vehicle crashes? Upstream is going towards the accident, downstream is away. What is the upstream buffer? A space after upstream taper and before the incident area that gives extra protection to emergency responders. What is the downstream buffer space? Area in termination space that gives emergency personnel extra protection in incident area before the downstream taper. What is the blocking vehicle? An emergency vehicle in a taper to block traffic from staying in lane. What is the activity area and what is in it? Area where emergency personnel work. Has upstream buffer space and incident area. What is the incident area? Area where the incident ended up. What are the emergency responders that aid in traffic incident management? • Law Enforcement • Fire Service • Rescue • EMS (Ambulance) Where do the emergency responders park in traffic incident management? • Law Enforcement - Early warning at the beginning of the transition area
