Contermeasures for Wrong-Way Movement on Freeways: Overview of Project Activities and Findings;Research rept. Sep 02-Aug 03

摘要

Several crashes in the Texas Department of Transportation (TxDOT) Fort Worth District have brought attention to the hazard of wrong-way drivers. A search of newspaper articles revealed that the problem of wrong-way driving is not unique to Fort Worth and occurs throughout Texas. Members of the Fort Worth Traffic Management Team (TMT) identified locations with a history of wrong-way entries and assessed potential countermeasures. During the review process it was determined that research was needed to understand and develop effective countermeasures for wrong-way movements onto freeways and other restricted roads. This research provides TxDOT staff with preventive measures for reducing the frequency and severity of wrong-way entries onto freeway facilities throughout Texas. Researchers performed the following tasks during the project: established state-of-the-practice on safety, design, and operational issues for wrong-way movement on freeways; surveyed state DOTs to get information on typical wrong-way signing and marking and any innovative practices; quantified the frequency, severity, and other important characteristics of wrong-way crashes in Texas based on a review of crash reports and coordination with 911 public safety answering points; identified available countermeasures to reduce wrong-way movements and crashes; evaluated the feasibility and applicability of the available countermeasures to address Texas problems; documented typical situations that were more likely to produce wrong-way entry issues; developed a guidelines/recommended practices for application of wrong-way countermeasures and treatments; and developed a checklist for field crews to use for reviewing wrong-way entry issues or suspected problem locations.
