Book Description
A wrong-way car stop device was installed on the East Ponce de Leon Avenue exit ramp from I-285 southbound near Atlanta. The device installed is a spring mounted collapsing curb that will collapse when hit by exiting vehicles but will obstruct entering vehicles. This device was evaluated, the wrong-way entry problem in the Atlanta area was assessed and the state-of-the-art in wrong-way entry preventatives was surveyed. Time- lapse video taping was used to observe the wrong-way car stop device. During 17 nights of taping a total of 6 wrong-way movements were observed, and one of these proceeded past the device and out of view of the camera. Findings of the research are that further steps should be taken to reduce wrong-way entries; that ramp signing and marking should be periodically inspected and maintained; and that the device is sufficiently durable and should be considered where less expensive methods of preventing wrong-way entries are not effective.

Book Description
During this 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 preventative 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 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.

Book Description
The report on design of urban streets was prepared as the participant's notebook for a four and a half day training course of the same title which has been conducted for a number of Federal, state, and local agencies. The report provides practical, state-of-the-art information to aid in design and operation of streets and highways, with emphasis on functional, operational, and safety aspects of design which apply to minor design revisions as well as to major reconstruction and new construction.
