Further Reduction in Incidences of Wrong-way Driving

Report No: 77-R45

Published in 1977

About the report:

Over a four-year period beginning in 1970, wrong-way incidents and accidents on Virginia's interstate highways were reduced by 50% and those on non-interstate 4-lane divided highways by 70%. However, since 1975 an upward trend has been observed on interstate roads while the downward trend has continued on non-interstate roads. The report discusses engineering measures taken to reduce wrong-way driving; namely, the use of reflectorized pavement arrows on ramps, the elimination of pavement flares, the provision of stop lines across exit ramps near their junction with crossroads, continuation of the pavement edge line across exit ramps, continuation of double-yellow lines on 2-lane divided crossroads opposite exit ramps, reduction of the width of crossovers across exit ramps, additional guidance to local drivers on new interchanges, informing the driver of the geometry of the intersection before he enters it, and providing guidance for drivers at T-intersections without a crossover.
