Pedestrian crashes occur where large numbers of pedestrians travel within complex roadway systems with high traffic flow. There are several personal and environmental correlates of injury risks to pedestrians including traffic flow, density, education level, English fluency and socioeconomic status (SES). Pedestrian injuries have a greater negative impact on those of lower SES. Previous studies show that disparities exist among populations dependent on SES with regard to the incidence and outcomes of pedestrian crashes. The purpose of this study is to explore the relationship between personal and environmental risk factors within a large economically and culturally diverse county in Southern California.
