What is special about the ExtremeRange mode?

0

The ExtremeRange mode is especially attractive to the law enforcement community. A police cruiser traveling at an extremely high rate of speed needs all of the distance it can get when it comes to preempting traffic signals – the greater the speed of the vehicle, the less time it takes to cover a fixed distance. A vehicle traveling at 100 mph will cover approximately 150 feet per second. Therefore, the 12 seconds (or less) that it would take to descend upon an intersection that can normally be accessed from 1800 feet out might not be enough time for the traffic signal to cycle into the preemption mode, clear the traffic, and safely pass through the intersection. The ExtremeRange mode preempts the light at distances up to 2500 feet.
