| 摘要： | This study examined the effects of side-mounted yellow light-emitting diode (LED) rectangular rapid-flashing beacons (RRFBs) at uncontrolled marked crosswalks in a series of experiments. Many methods have been examined to increase driver yielding behavior to pedestrians at multilane crosswalks at uncontrolled sites with relatively high average daily traffic (ADT). Only treatments that employ a red phase have consistently produced sustained high levels of yielding in previous studies. A series of five experiments examined the efficacy of RRFBs to increase driver yielding behavior. These studies examined the effects of RRFBs at 22 sites in 3 cities in the United States (St. Petersburg, FL; Washington, DC; and Mundelein, IL). Data were also collected over a 2-year follow-up period at 18 of these sites to determine the long-term effects of the RRFB treatments. Another objective of the study was to compare the RRFB with a traditional overhead yellow flashing beacon and a side-mounted traditional yellow flashing beacon. A final objective of the study was to attempt to identify ways to further increase the effectiveness of the treatment. Variants subjected to evaluation included mounting additional units on a median or pedestrian refuge island and aiming the RRFB system to maximize brightness at a target site. / Supplementary Notes: See also PB2011-103288.
