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. /Author/
