Gainesville, Florida Increases Pedestrian Safety by Implementing Year-Long ProgramIn large cities, pedestrians account for 40% to 50% of traf-fic fatalities.

At the untreated generalization sites, yielding for staged crossings sites averaged 37% during baseline and 59% by the end of the study. There was statistically higher yield-ing for unstaged pedestrian crossings than for staged crossings at all but one site that started with very high baseline yielding. Yielding for unstaged crossing aver-aged 45% during baseline and 83% at the end of the study.

One possible explanation for this finding is that pedes-trians may cross more assertively when crossing in the unstaged or natural situation than pedestrians who were staging the crossing.

DiscussionDrivers who receive citations are aware of the program, but the intent of an HVE operation is to persuade another 1,000 drivers or so of the increased risk of getting a cita-tion for each ticketed driver. Encouraging compliance with the pedestrian crossing laws increases the safety of pedestrians. One way to achieve this is to make sure that drivers who pass a stopped vehicle know that the stop is for a pedestrian crossing violation. Gainesville selected busy streets for the operations where officers could make numerous stops and used portable message signs to alert passing drivers about the stop. Widely publicizing that police are enforcing pedestrian right-of-way at cross-walks can increase the perception of enforcement. Com-munity feedback signs placed on busy Gainesville streets conveyed the message that yielding to pedestrians is an important safety issue. Updating the percentages weekly showing how many drivers properly yielded conveyed the message that Gainesville drivers were improving, but had not reached 100 percent compliance yet.

High-visibility enforcement led to a slow and steady increase in the percentage of drivers yielding right-of-way to pedestrians over the course of the year. Yielding began to increase during the first wave when officers issued mainly warnings and handed out flyers announcing upcoming enforcement efforts. Yielding increased more when officers issued citations. Yielding increased again when Gainesville added paid ads, in-street signs, and feedback signs. Yielding also increased steadily at com-parison sites, showing that the program generalized to other crosswalks. There was more yielding at comparison sites that were closer to the treated crosswalks. The steady increase in yielding behavior across treated and untreated sites suggests a sustained change in driving culture.
