Effectiveness of Radar Signs and Radar Speed Signs
Radar Signs - A Proven Traffic Calming Technique
Traffic calming studies repeatedly show that when alerted by a radar sign, speeders
WILL slow down up to 80% of the time. Typical average speed reductions are 10-20%,
and overall compliance with the posted speed limit will increase by 30-60%.
Take at a look at how our traffic calming techniques demonstrate the effectiveness
of radar speed signs with historical data and the resulting impact from actual radar
sign locations. In order to view our documentation about the effectiveness of radar
signs, you'll need the free Adobe Acrobat Reader™, which you can download

- 22 months of operation shows how radar signs continued decline in average speeds
- 6 months of operation showing how radar signs effectively caused a shift of peak speeds to lower speeds
- 1.5 years of radar speed sign operation shows 55% more vehicles obeying posted speed limit (PSL)
- 2 years of radar sign operation shows consistent, long-term reduction of speeds
- 2 years of driver feedback sign operation shows average speeds maintain drop of 3.5 MPH
