Additional Characteristics of Crashes on Rural Two-lane Highways


Book Description

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 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.
