Wrong-way Driving at Selected Interstate Off-ramps

Report No: 81-R30

Published in 1980

About the report:

This study was designed to evaluate, on interstate roadways in Virginia, the use of a technique developed in California for estimating or determining incidences of wrong-way driving at off-ramps. Also, information gained from a survey of the available literature on the subject was compiled. Based on data obtained from selected off-ramps in Virginia, it is apparent that a large number of wrong-way maneuvers occur. The wrong-way counter proved to be a good device for detecting wrong-way maneuvers and the data it provided could be beneficial to traffic engineers in designing countermeasures. Recommendations are given for the use of wrong-way counters in Virginia and for the adoption of sign placement criteria used by California.
