Safety Effects of Cross-Section Design on Rural Multilane Highways

Source: Federal Highway Administration

This study examines the effects of various cross-section-related design elements on accident frequency and developed an accident prediction model for rural, multilane, nonfreeway highways.

As a review of the data indicated that there were very few pedestrian and bicycle accidents reported on multilane rural roads (i.e., less than 2 percent of all reported accidents), these accidents were excluded in an attempt to restrict accidents to those that are more highly correlated to cross-section design of multilane rural road segments.
