How It Works 

During the one month speed study, the sign is first programmed to “stealth mode” (no display) to collect baseline data from passing vehicles. After one to two weeks, the sign is changed to “display” mode. In this mode, the sign continues to collect data but also displays the speed of oncoming vehicles and flashes a strobe when a motorist violates the speed limit. Speed is recorded in 5 mph bins and volume is recorded in 1 hour intervals.
