WRONG-WAY MOVEMENTS ON DIVIDED HIGHWAYS

The purpose of this research was to study the problem of wrong-way movements on divided, rural highways in Indiana. The research was in two parts: a general review of the characteristics of wrong-way accidents that have occurred in Indiana, and an investigation of various alternatives that could be used to reduce wrong-way movements. The basic data were obtained by searching the Indiana State Police accident records for wrong-way accidents that occurred in 1970, 1971, or 1972. Field investigations were made at each accident site to supplement data shown on the accident records and to determine the physical characteristics of access point where wrong-way movements originated. Wrong-way accidents were exceptionally severe with 39 deaths resulting from 96 accidents over a three year period. Studies of wrong-way drivers indicated that only 31% of them were not drunk, were not old (over 65) and/or were not fatigues (driving between 12:00 a.m. and 6:00 a.m.). Conditions at typical wrong-way movement origin sites included darkenss, low land-use and low traffic volumes. Any measure that improves the driver's visibility and perception of access points to divided highways would decrease wrong-way movements. Possible measures included night lighting, raising the elevation of crossroads, making medians more distinct and the use of simple, understanding configurations. At certain locations, the use of additional channelization and barrier curbs will direct traffic in the right direction and could block wrong-way movements.
