Opticom Preemption Signals Being Installed at Major Fresno Intersections
06/01/2007

Signal preemption at major intersections around Fresno is the next step that the City of Fresno Public Works Department is taking to make it easier for the City of Fresno Fire Department to reach their goal of a “four minute response time.” The Opticom preemption signals not only help with the response time of the Fire Department but all emergency personnel.

When a vehicle equipped with an emitter approaches a traffic signal it sends out an infrared light to the receiver next to the lightbox, giving that vehicle the right-of-way in traffic. This process does not interfere with the intersection’s light cycle.

72 intersections currently have the Opticom preemption signals, a 415 percent increase from 2003. In the next two years the Public Works Department expects to see 51 more intersections equipped with preemption signals. This will make more than a quarter of all signals, 123 out of 480, outfitted with preemption signals.

The City of Fresno’s preemption program is compatible with the City of Clovis’ signals, which has made emergency vehicle response times quicker and safer. The City of Fresno’s Transportation Department (FAX) is also looking into using the Opticom preemption system, to ensure bus service stays on schedule.

The preemption signals are another example of how the City of Fresno and the Department of Public Works are seeking to make driving the roads safer throughout the city.
