Police Utilize Digital Radar Sign to Reduce Speeds, Improve Pedestrian Safety in Greenburgh NY

Greenburgh, NY, USA

At a Glance

To combat speeding on local roads, the town of Greenburgh's police department utilized a digital radar sign that warns speeding drivers and collects traffic data. This solution increases resident safety and the data it collects allows police to more efficiently focus their enforcement efforts.

Problem Addressed

The city of Greenburgh, NY was receiving municipal complaints regarding speeding vehicles on local roadways. The problem was too widespread for the police to effectively enforce it. The issue was first brought forward by residents, and then verified using the town’s radar recorders. These speeding vehicles put all residents at risk including pedestrians and bicyclists. Message boards that display the number of tickets the police had issued in a certain location as a way to show the consequences of speeding were considered, however the message boards' large size made them unsuitable for residential neighborhoods. The police department needed a more portable solution that would effectively discourage speeding through the traditional method of displaying the driver's speed as well as by relaying the number of tickets police had written that week.

Greenburgh, NY used/is using Traffic Logix's digital radar signs to address this/these challenge(s).

Solution(s) Used

The town began using the SafePace 800 digital radar sign from Traffic Logix in conjunction with police enforcement to address their speeding problems. The sign is completely customizable with regard to messaging or differing speed limits and concerns on various streets. In the case of the town of Greenburgh, the signs were specifically programmed to display the vehicle’s speed if it was exceeding the limit by 1-4 miles per hour. If a motorist was driving more than 5 miles over the posted limit, the sign would flash strobe lights and display “Too Fast, Slow Down.”

In rolling out the new program, periods of police enforcement in high-priority areas were followed by the installation of a SafePace 800 sign. Because the sign is portable, it can be deployed on many streets without having to purchase multiple signs. The sign’s digital display allows the town to deter speeders by showing the number of tickets issued by police in the same location in the last week, as well as warn drivers when their speed exceeds the posted limit. This was a new approach to slowing drivers down by displaying the consequences for speeding.

Because Traffic Logix speed signs are all web-enabled, Greenburgh police were able to receive traffic statistics and data reports from these locations. This data allows them to more efficiently police high-priority areas without the need for additional officers.


  1. Limits the need for police enforcement - drivers are incentivized to slow down by seeing the number of tickets issued in the same location.
  2. The new speed signs have been out on patrol 90% of the time.
  3. Police Sergeant Reckson commented “We love it. If you sit and watch it, you’ll notice drivers instantly slow down.”
  4. The portability of the sign allows the town to use it in multiple locations.

Lessons Learned

  1. The implementation of one week of police enforcement in the area, followed by one week of sign deployment has proven to be especially effective in stopping speeders.
