CORRECT ANSWER-• Advance Warning Area Il` Il` Il` Il` Il`
- Notifies upstream traffic of emergency situation ahead
Il` Il` Il` Il` Il` Il` Il` Il`
• Transition Area
Il` Il` Il`
- Traffic is "transitioned" away from Activity Area
Il` Il` Il` Il` Il` Il` Il` Il`
• Activity Area
Il` Il` Il`
- Buffer Space Il` Il`
- Incident Space • Termination Area Il` Il` Il` Il` Il`

Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
Describe multiple traffic control devices that can be used to provide advanced warning. -
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`

use during major incidents
Il` Il` Il` Il` Il`
• Tapers can be set up using cones or flares - skip lines provide a useful guide for Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
measuring distances

Il` Il`
What is a taper in traffic control? - CORRECT ANSWER-The taper is the transition area
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
Il`
where a driver must adjust their travel path. Tapers are also used to transition traffic
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
Il`
Il` Il` Il` Il`
back to its normal path of travel at the end of the area.
Il`
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`

Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
Il`
much equipment as is available on the scene Il` Il` Il` Il` Il` Il` Il`
Il`
• Consider roadway speed - the higher the speed the longer the taper
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
Il`
• Tapers should be set up to accommodate for sight obstacles
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
Il`
• Try to maximize the spacing covered with the cones available at that time
Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
• Block as much of the roadway as needed and extend the taper out as far as possible Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
to allow drivers adequate time to merge
Il` Il` Il` Il` Il` Il` Il` Il`
,• Most high-speed highways in Wisconsin use a skip line distance of 50 feet from the Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il` Il`
start of one line to the start of the next (or from the end of one to the end of the next)
