Prior to radar sign installation look for any obstructions (telephone poles, large tree limbs, other signage, etc.) that might interfere with proper operation of the driver feedback sign.
Installing the sign on the same side of the street as parallel parking of vehicles could affect the radar performance of the driver feedback sign.
These guidelines and recommendations for driver feedback and radar sign installation provide the best practices for the installation process to assure successful, accurate and effective traffic calming.
Do not install a solar powered driver feedback sign under a tree. Summer leaves on the tree could impact solar recharging.
The driver feedback sign should have at least 75’ of straight road for on-coming traffic.
The driver feedback sign should be installed no more than 5 feet' from the road curb. At more than 6 feet off the road, the sign will take the eyes of the drivers an unsafe distance from the roadway.
The sign direction should be perpendicular to the road with the radar pointing directly at the curb, not at the center of the road.
