This is the third volume in a series of six publications providing research results on the safety effectiveness of highway design features. This volume discusses relationships between cross-sectional elements and accident experience, along with the accident reductions expected due to related roadway safety improvements. All of the information on crash relationships for lanes, shoulders, and bridges (and corresponding effectiveness information for countermeasures) are for two-lane, rural roads only. Most of the discussion on roadside effects relates to rural two-lane roads, although multilane roads and urban areas are included in some of the discussion (e.g., relating to utility pole accidents and countermeasures). The discussion of median design includes only multilane Interstate and parkway roads in rural areas.
