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.

By discussing statistical concepts in the context of transportation planning and operations, Transportation Statistics and Microsimulation provides the necessary background for making informed transportation-related decisions. It explains the why behind standard methods and uses real-world transportation examples and problems to illustrate key conc

The purpose of the study was to identify the single-vehicle run-off-the-road (SVROR) accident mitigation techniques that are currently in use in Texas, and to assist the Texas State Department of Transportation (TxDOT) highway engineer in identifying areas that may be susceptible to SVROR accidents. Using the accident records from TxDOT from 1983 to 1990 to identify factors common to rural, four lane or more divided highway SVROR accidents, a prediction model equation was developed. The prediction modeling was useful in identifying the primary factors involved in rural, four lane or more divided highway SVROR accidents. A method of identifying locations susceptible to SVROR accidents was developed. Recommendations for selecting and using the different types of shoulder treatments with respect to different pavement surfaces and for different climates were also made.
