  • Abstract:
    Bicycle crashes are a major traffic safety concern in Florida. In 2014, Florida led the nation with 139 bicyclist fatalities, representing approximately 20% of the nation’s total. This project aims to improve bicycle safety on Florida’s state roads by conducting a comprehensive study focusing on both statewide and site-specific analyses. The specific project objectives include: (1) review and summarize existing literature on bicycle safety; (2) identify specific contributing causes and patterns of bicycle crashes; (3) identify and analyze bicycle hot spots for crash causes and potential countermeasures; and (4) develop Florida-specific Crash Modification Factors (CMFs) to assess the safety effects of common engineering treatments on bicycle safety. ; In this study, an extensive literature review focusing on the methods to identify bicycle hot spots and findings on bicycle crash causes, crash contributing factors, and potential countermeasures was first conducted. A descriptive trend analysis was then conducted based on a total of 26,036 bicycle crashes that occurred during 2011-2014. The top five bicycle crash hot spots in each Florida Department of Transportation (FDOT) district were then identified using spatial analysis in ArcGIS. These hot spots experienced a total of 2,954 bicycle crashes during the four-year analysis period. Police reports of these crashes were reviewed in detail to identify specific bicycle crash types. Crash contributing factors related to each crash type along with specific countermeasures were then identified. Macroscopic spatial analysis was conducted to model the relation between demographic, socio-economic, roadway, traffic, and bicycle activity data at the census block group level and bicycle crash frequencies in Florida. Finally, cross-sectional analysis was conducted to develop Florida-specific CMFs for bicycle crashes for different roadway segment and intersection facility types.
