PROVO, UT—An impressive signal optimization project in Clark County, Washington, has been recognized by state leaders as an outstanding example of the efforts being made throughout Washington State to reduce traffic fatalities and improve driving conditions.

Clark County Public Works received a 2014 Target Zero award in the category of intersections, for its program to update traffic signal systems. According to Rob Klug, the traffic operations and engineering lead for Clark County Public Works, many traffic signal systems in the county date back to 1982, and the out-of-date equipment has contributed to accidents.

Part of the upgrade includes replacing loops with SmartSensor Advance and SmartSensor Matrix. SmartSensor allows the county to update its traffic systems without incurring the costs of burying loops in the road. It also alleviates the dangers posed to workers and the traffic disruptions caused by the lane closures required to install loops.

“We went from a system that had no information at all to a full ITS architecture design, where we have a central system that talks to each signal once per second,” Klug says. “We have about 85 percent of all of our signals on the system now.”

Klug says the information provided by the SmartSensors gives them a richer set of data to work with. “We can do a better job of moving cars because we have a better idea of what traffic is doing,” he says.

The state of Washington launched the Target Zero Strategic Highway Safety Plan in 2000, with the goal to achieve zero traffic fatalities and zero serious injuries by the year 2030. Since 2005, the state has reported a steady decline in fatalities, and officials believe continued progress in programs like Clark County’s will help Washington lead the nation in “targeting zero.”

This year’s awards ceremony was held 16 April 2014 to honor those who have made significant contributions to the Target Zero program.
