Study Title: NCHRP Report 794: Median Cross-Section Design for Rural Divided Highways

Authors: Graham et al.

Publication Date: 2014

Abstract: This report presents guidelines for designing typical cross-sections for medians on new and existing rural freeways and divided highways. The report examines the interrelationships between median width, median slope, and the use of median barrier on crash risk and severity. The report should be useful to designers and safety analysts, particularly those responsible for agency standards.
