Law Enforcement Traffic Calming Applications and Solutions

Law Enforcement Traffic Calming Solutions

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 (optional), 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 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
TC-400 Installation

Residents love the signs because they can sit and watch drivers’ reactions. I’ve sat in my unmarked car and watched drivers get on the brakes when the sign starts flashing that they’re going too fast.

The signs are working well. From my unmarked vehicle, I have watched as cars react to the sign. It has slowed them down dramatically.

The city plans to use the traffic data to secure grants for sidewalks and other street improvements. The StreetSmart software has been very helpful with gathering the information that city operations need to develop the grant proposals.

TC-400 Portable Radar Speed Sign…Your Rapid Response Traffic Calming Weapon

The TC-400 battery power radar speed sign is lightweight and offers the ultimate in portable traffic calming. With its modular design and a universal mounting bracket, one person can easily install or relocate the TC-400 in minutes. The portability and ease of installation of the TC-400 make it easy to create a circuit to rotate the sign on a regular basis. Plus, with the universal mounting bracket, the TC-400 can be used in hundreds of places where a speed trailer simply won’t fit – and at less than half the cost.

Police departments across the country are finding that the TC-400 portable radar speed sign is more reliable, safer to use, more convenient to relocate, and is a much better investment than a traditional speed trailer.

  1. The lightweight design and easy carry handle allows 1 person to move the sign.
  2. Just lift the sign onto the bracket and secure with the fasteners.
  3. Close the sign, lock it, and you are done. It doesn’t get any easier than that.
