Abstract:

The research team started with a thorough review of horizontal curves and their impacts on traffic crashes. This review encompassed the following topics: characteristics of horizontal curves; impacts of horizontal curves on crash risk, frequency, and severity; and factors affecting crashes on horizontal curves. A comprehensive study was then conducted to investigate available data sources that contain reliable roadway geometry and inventory information. Curve-related parameters that can provide information the CRIS database were also examined. Then, a systematic data analysis was performed to identify the patterns and characteristics of curve-related crash misclassification in the CRIS database. Next, a methodological procedure to improve the identification of curve-related crashes was developed, automated, and evaluated. Finally, using the Texas Peace Officer’s Crash Reports (CR-3) of misclassified crashes, the research team comprehensively investigated potential causes for curve-related crash misclassifications in CRIS.
