Summary
This report documents a multidisciplinary intervention program designed to improve pedestrian safety at crosswalks in St. Petersburg, Florida, addressing high local pedestrian fatality rates that exceeded national and state averages. The study was motivated by the recognition that engineering, education, and enforcement strategies are most effective when combined. The Florida Department of Transportation contracted the Center for Urban Transportation Research to implement and evaluate a program modeled after the successful "Courtesy Promotes Safety" initiative in Canada. The primary objectives were to increase motorist yielding behavior from single-digit levels to over 70 percent, reduce pedestrian-motor vehicle conflicts by 50 percent, and enhance pedestrian comfort. The research followed a three-phase approach: community assessment, program implementation, and evaluation. The assessment involved analyzing crash data from 1994–1998, which revealed that fatalities clustered along major corridors like 4th Street and 34th Street, with victims predominantly being seniors or young children. Researchers also surveyed pedestrian comfort levels and audited crosswalk conditions, identifying deficiencies such as inadequate advance stop lines and lack of pedestrian signals. Based on these findings, specific intersections were selected for intervention. The implementation phase deployed engineering treatments, including advance stop lines, lead pedestrian intervals, scanning eyes on signal heads, and prompting signs. Education components included electronic message boards, school programs, and media campaigns. Enforcement efforts consisted of targeted warning programs for motorists failing to yield. The evaluation utilized a time-series design, comparing baseline observational data collected prior to interventions with post-intervention data. The study measured two key behavioral metrics: the percentage of motorists yielding to pedestrians and the frequency of pedestrian-motor vehicle conflicts (instances requiring evasive action). Data were collected at both signalized and unsignalized intersections. The methodology allowed for the isolation of intervention effects by tracking changes in behavior over time as different components were introduced. The report details the specific locations and timing of these interventions to contextualize the observed behavioral shifts. The findings demonstrated that the multidisciplinary approach significantly improved safety outcomes. Motorist yielding behavior increased substantially across the studied intersections, moving from low baseline rates toward the program’s goal of over 70 percent compliance. Concurrently, the frequency of pedestrian-motor vehicle conflicts decreased, indicating a reduction in dangerous interactions. The study concluded that combining engineering, education, and enforcement is more effective than isolated measures. It provided a replicable model for other communities, emphasizing the importance of community assessment to target interventions effectively and the value of inter-agency cooperation in achieving sustained behavioral change among drivers and pedestrians.
Key finding
