Engineering Measures for Reducing Wrong-way Driving

Report No: 76-R8

Published in 1975

About the report:

Presented is an evaluation of engineering measures instituted in Virginia to reduce incidences of wrong-way driving. Also discussed are the data collected in a survey of wrong-way driving incidents, the causes of wrong-way entries determined through recent on-site investigations, and corrective measures for preventing them. Measures found highly effective were the installation of reflectorized pavement arrows on ramps and the elimination of corner flares at the junction of exit ramps and crossroads. Measures suggested for further reducing wrong-way entries are (1) continuing the pavement edge line across the exit ramp or placing the stop line very close to the crossroad such that it lies within the zone illuminated by the low beam headlights of a vehicle traveling the crossroads; (2) channelizing the crossover opposite the exit ramp; and (3) placing signs and pavement markings for high visibility and legibility at night under low beam headlights.
