Since 2005, pedestrian deaths nationwide had decreased by more than 16 percent, averaging about 200 fewer deaths per year. However, preliminary data collected from the first six months of 2010 show that the decrease had apparently slowed or stopped--seven more pedestrians died in the first six months of 2010 than for the same period in 2009 (Fogel, 2011). Car - pedestrian collisions at crosswalks were serious matters that required continuous research on increasing pedestrian safety at crosswalks. In this paper, although (e.g., Cox, et al., 2010; Houten & Retting, 2001; Huybers, Van Houten, & Malenfant, 2004; Reagan, Sifrit, Compton, Tenebaum, & Van Houten, 2010) have all contributed to the behavior interventions in pedestrian safety, we followed the procedure of earlier research conducted by Crowley-Koch et al. (2011) on the effects of pedestrian prompts on motorist yielding at crosswalks. In addition, this current study extended the previous study by examining the effects of a pedestrian prompt through a wearing of a Bell® Spider flasher over left arm at resting position, on motorist yielding at a controlled crosswalk. Implications and future directions are discussed.
