HART provides municipalities with FREE speed studies of local roads. More commonly known as the “Your Speed Is” sign, the Speed Sentry sign collects data on traffic volumes and motorist speed. This data is evaluated by HART staff and the municipality is provided with a written report documenting data with charts and graphs.
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.
