AbstractIn recent years, a surge in pedestrian fatalities has necessitated a close examination of their causes. This study, based on five years of data from the Fatality Analysis Reporting System (FARS) and the American Community Survey (ACS) in Tucson, Arizona, aims to determine the impact of the racial composition of census blocks on these fatalities. Between 2017 and 2021, 142 pedestrians lost their lives in Tucson, Arizona. Furthermore, annual pedestrian fatalities during this five-year period increased by 57 percent. The primary objective of this study was to investigate the presence of a discernible geographic pattern in pedestrian fatalities, shedding light on the relationship between demographics, the built environment, and pedestrian fatalities. This study examined the potential influence of age, income, and race on pedestrian fatalities. Of those categories, race proved to be the most statistically significant. Analysis of FARS data revealed a significant bias toward fatalities involving non-white and Hispanic individuals during this five-year period. A comparison of FARS and ACS data during this period displayed a higher incidence of pedestrian fatalities in census blocks with high percentages of non-white and Hispanic populations. Furthermore, analysis of the FARS data indicated a non-random distribution of pedestrian fatalities. Subsequent regression analysis quantified the link between the racial composition of neighborhoods and pedestrian fatalities in Tucson. While this study revealed a statistically significant association between the racial composition of census blocks and pedestrian fatalities, it by no means provided a comprehensive explanation for pedestrian fatalities and their increased frequency.
