In 2016, Texas had the ninth highest pedestrian fatality rate in the United States at 2.44 per 100,000 population. In a review of the U.S. counties with the highest number of pedestrian fatalities in 2016, Texas had three counties within the top 10 counties with the highest number of pedestrian facilities with Dallas County being fourth. Similar to the rest of the United States, pedestrian crashes (both total crashes and high-severity crashes — crashes with fatal and incapacitating injuries) have been increasing in the Texas Department of Transportation’s (TxDOT) Dallas District over the last 10 years. Thus, the District requested that the Texas A&M Transportation Institute (TTI) investigate these types of crashes to better understand the issue.
This analysis provides the Dallas District with a foundational understanding of the demographics, geographic areas, roadway facilities, and causal and risk factors associated with its pedestrian crashes. Through data mining and direct demand modeling, researchers were able to estimate pedestrian exposure and ultimately identify freeway and non-freeway hot spots. The non-freeway hot spots were derived by using a comprehensive examination that identified high-risk intersections by their control type (signals or stops).
Finally, future research is recommended to test the transferability of the pedestrian volume model and the safety performance functions developed in this project to other urban areas such as Fort Worth, Houston, San Antonio, and Austin.
