Accidents involving pedestrians dropped 17% during the two years after St. Petersburg installed solar-powered flashing beacons at 33 intersections throughout the city, earning the Stormwater, Pavement, and Traffic Operations Department a 2009 National Roadway Safety Award from the Federal Highway Administration and Roadway Safety Foundation.
On average, yielding rates jumped from 2% to 82% at crosswalks with the pedestrian-activated beacons.
In federal tests, only the standard traffic light and high-intensity activated crosswalk, which are larger and use a solid red indication, have produced better results than the LED Enhancer. Developed by a local company, R.D. Jones' Stop Experts Inc., the system is also being used in Mundelein, Ill., Las Cruses, N.M., and Washington, D.C.
