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.

TRB¿s National Cooperative Highway Research Program (NCHRP) Report 617: Accident Modification Factors for Traffic Engineering and ITS Improvements explores the development of accident modification factors (AMFs) for traffic engineering and intelligent transportation system improvements. AMFs, also known as crash reduction factors, are designed to provide a simple and quick way of estimating the safety impacts of various types of engineering improvements, encompassing the areas of signing, alignment, channelization, and other traffic engineering solutions.
