This report provides information on year 2 activities for Texas Department of Transportation (TxDOT) Project 0-4048 including: characteristics of animal crashes and potential treatments; additional insight into characteristics of crashes on low-volume, rural two-lane highways using information provided by officers in their crash narratives; a methodology for conducting before-and-after studies; and findings for before-and-after evaluations performed at four sites. Approximately 3800 animal crashes occurred on Texas on-system, rural highways in 1999. The before-and-after methodology used in this project involves a 16-step process in which researchers gathered, reduced, and analyzed information on site characteristics, crash and volume history, and improvement details.
