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

Report No: 80-R4

Published in 1979

About the report:

Recently completed research had proven the feasibility of using raised pavement markers to alert wrong-way drivers to their errors. In that research, however, the raised markers had been placed only in areas where-snowplowing was not a problem; therefore, the research described in the present report was undertaken to determine if problems would be encountered in adapting the system employing the raised markers to areas where snowplowing is prevalent. Based on the results of this research, it is believed that the method described for placing the raised pavement markers is effective in protecting them from damage by snowplows. The method of grooving allows the markers to be protected from damage and provides effective retroreflection for warning wrong-way drivers. It is recommended that the system of raised pavement markers placed as noted in this report be considered for placement at ramp areas or similar locations where wrong-way entries are a problem.
