Installation of Raised Pavement Markers for Reducing Incidences of Wrong-way Driving

Report No: 77-R58

Published in 1977

About the report:

On the basis of previous research, raised pavement markers were installed at two interstate off-ramps known to have experienced incidences of wrong-way driving to further evaluate their effectiveness in alerting motorists entering from the wrong-way of their mistake. Descriptions of these installations are given in the report along with the results of the evaluation, which included a subjective investigation of the visibility and alerting characteristics of the markers and a determination of their durability qualities. Based on the results it is felt that the configurations of markers used are effective in alerting drivers as a result of their viewing an unexpected phenomenon. It is recommended that the raised pavement markers, placed in configurations as noted in the report, be considered for placement in ramp areas or similar locations where wrong-way entries have been a problem.
