Disadvantaged population groups are disproportionately represented in bicycle crashes. Individual Black and Hispanic bicycle riders, and areas with higher populations of non-white residents, lower median income, and high poverty experience bicycle crashes more frequently than others. Although existing research has explored the role of socioeconomic status and the built environment in predicting crash frequency, few scholars have studied how those factors account for the disparities along racial and ethnic lines. Using a database of 7,279 bicycle crashes in the San Francisco Bay Area, this study examines the influence of socioeconomic, land use, and transportation characteristics as potential causes of differences in bicycle crash occurrences among racial and ethnic groups in the San Francisco Bay Area. After analyzing both traditional and Bayesian count models, this study finds no evidence that transportation infrastructure or bikeway presence is associated with differences in bicycle crash frequency among white and Hispanic victims, though areas of higher poverty and higher concentrations of Hispanic residents experience more crashes, controlling for other factors. The findings are encouraging along lines of transportation equity, but suggest a need for further research that accounts for exposure and behavior to reach robust conclusions about bicyclists’ individual risk.
