Law Enforcement Traffic Calming Applications and Solutions

Law Enforcement Traffic Calming

“The signs are working well. From my unmarked vehicle, I have watched as cars react to the sign. It has slowed them down dramatically.” — Chief Alex Collinge, City of Eureka, IL Police Department

“Radarsign gives my officers the ability to better manage their time and the flexibility in how we monitor and enforce speed limits. We picked Radarsign after looking at four manufacturers and liked that it was armored and durable against vandalism.” — Captain Walter Horton, Carrboro, NC Police Department

One of the many duties of law enforcement is to help keep the roads safe. However, officers cannot be everywhere, all of the time. Radar speed signs serve as an extra officer, 24/7. They reinforce speed limit awareness by alerting drivers of excessive speeds. And when used with Streetsmart traffic data reporting software option, the radar speed signs provide key data to quantify speeding problems. This allows police and sheriff’s departments the ability to intelligently deploy limited police staff for enforcement. 

Radar speed signs provide an effective, reliable, and affordable traffic calming solution by for reducing speeding drivers. Tests repeatedly show that:

  • Speeders will slow down up to 80% of the time when alerted by a radar speed sign
  • Typical speed reductions are 10-20%
  • Overall compliance with the posted speed limit will go up by 30-60%
  • Radar speed signs are particularly effective at getting “super speeders”—speeders driving 20 mph or more over the posted speed limit—to slow down
