Impacts of Led Brightness, Flash Pattern, and Location for Illuminated Pedestrian Traffic Control Device
Impacts of Led Brightness, Flash Pattern, and Location for Illuminated Pedestrian Traffic Control Device
Illuminated traffic control devices, such as rectangular rapid-flashing beacons (RRFB), have been shown to increase the number of drivers yielding to crossing pedestrians. Evaluations of field installations of these devices have been conducted in several locations, including Florida, Texas, Oregon, Michigan, Arizona, Wisconsin, and Calgary, AB. (See references 1 through 10.) Before-after studies have shown a large increase in driver yielding between the before period (range of 1 to 83 percent) and the after period (range of 38 to 98 percent). While driver yielding has always increased after the RRFB installation, there are still examples of low yielding in some locations. Studies have shown a wide range in driver yielding to the RRFB, with values extending from a low of 22 percent to a high of 98 percent.
