The Richardson Police Department shared their concern about the hazardous situation to the officers trying to enforce red light violators. Collaboration between the police department, the engineering department and the traffic engineer enabled them to develop an innovative, cost-effective solution to the traffic problem. A white light was wired on the back of the signal heads or on the cross beam of the light assembly. The white light was activated when the red light received power. The officer could either flag the motorist over or fall behind the vehicle and safely make the traffic stop.
Installation requires about six hours, using a two-person crew.
During a two-day enforcement period officers issued more than 300 citations for red light running. The judges were shown one location where the lights were installed and allowed them to monitor the operation of the lights.
