ACC LEA 720 Phase 3 Final Exam Guide 2024 Latest/verified What is the definition of Traffic Incident Management(TIM)? - CORRECT ANSWER-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? - CORRECT ANSWER- §Responder safety §Safe, quick clearance §Prompt, reliable, interoperable communications. What are the four compenents of a Traffic Incident Management Area (TIMA). - CORRECT ANSWER-• 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. - CORRECT ANSWER-• 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? - CORRECT ANSWER-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? - CORRECT ANSWER-• 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? - CORRECT ANSWER-Upstream is going towards the accident, downstream is away. What is the upstream buffer? - CORRECT ANSWER-A space after upstream taper and before the incident area that gives extra protection to emergency responders. What is the downstream buffer space? - CORRECT ANSWER-Area in termination space that gives emergency personnel extra protection in incident area before the downstream taper. What is the blocking vehicle? - CORRECT ANSWER-An emergency vehicle in a taper to block traffic from staying in lane. What is the activity area and what is in it? - CORRECT ANSWER-Area where emergency personnel work. Has upstream buffer space and incident area. What is the incident area? - CORRECT ANSWER-Area where the incident ended up. What are the emergency responders that aid in traffic incident management? - CORRECT ANSWER-• Law Enforcement • Fire Service • Rescue • EMS (Ambulance) Where do the emergency responders park in traffic incident management? - CORRECT ANSWER-• Law Enforcement - Early warning at the beginning of the transition area or positioned prior to the upstream buffer space downstream of the blocking vehicle • Fire Service - Upstream at the end of activity area buffer space in the incident space • Rescue - In the activity area or in the downstream buffer space • EMS (Ambulance) - Incident space, downstream of the actual event What are the two ways to park as an officer in traffic incident management? - CORRECT ANSWER-Linear, and angled usually at 20-45 degree angle. What are some considerations when positioning a vehicle in Traffic Incident Management? - CORRECT ANSWER-- Current conditions, such as roadway geometry, sight distance, weather, etc. - Safety of other responders, crash victims and passing motorists - How vehicle positioning impacts vehicle visibility, including vehicle markings and vehicle emergency lighting How does scene breakdown impact traffic conditions? - CORRECT ANSWER-During scene breakdown and demobilization, the speed of traffic typically begins to pick up and there is less traffic control protecting responders. It is important that a de-commit plan be developed to remove personnel, apparatus, victims, bystanders and vehicles safely from the scene. How are minor, intermediate, and major traffic incidents defined? - CORRECT ANSWER-Minor incidents last less than 30 minutes, like disabled vehicles or minor crashes. Intermediate incidents last between 30 minutes and 2 hours, accidents involve multiple vehicles and personal injuries Major incidents last longer than 2 hours, fatalities or serious crashes. What are Secondary Crashes? - CORRECT ANSWER-Secondary Crashes are crashes that occur within the incident scene or within the queue or backup, including the opposite direction, resulting from an original incident What is Wisconsin's move over law? - CORRECT ANSWER-Wisconsin Motorists are require to move over or slow down when approaching an emergency or maintenance vehicle stopped on the side of the road. Some things to consider when working alongside highways? - CORRECT ANSWER- §Never trust approaching traffic in either direction §Never turn your back to approaching traffic §Look before you move §Plan an escape route §Don't allow yourself to get tunnel vision, maintain a view of the "big picture" Maintain knowledg
