STC delivers radar speed signs to Maricopa County, AZ

TEMPE, AZ - 03/01/2012 - Solar Traffic Controls, distributor for TraffiCalm's driver feedback sign in AZ and NM, recently delivered radar speed signs to Maricopa County DOT for installation along a desert route.

Popular with motorcyclists, the route lies north of Phoenix. Both locations along the roadway have had numerous collisions due to motorists' high speeds going into the turns despite cautionary signs warning of curves. Maricopa County decided to try a solar-powered driver feedback sign to reduce these accidents.

The county selected TraffiCalm's DriveBrite(TM) driver feedback urban sign which features 15-inch characters with a programmable flash and color presentation. The county chose to display solid amber characters when motorists were above a minimum speed but below the posted speed limit. Vehicles approaching slightly above the speed limit will see flashing amber characters warning them to slow down. Vehicles approaching at higher velocities see flashing red digits interlaced with white strobes around the display face.

Observation of driver response to the signs during a field visit showed many drivers hitting the brakes when the red digits were shown. The sign also includes data logging and a user-friendly software package for review of the data.

STC furnished the signs and the solar power systems to ensure operation 24/7/annually. AJP Electric provided the installation services for the county.
