Exploring the impact of access designs on crash injury severity on multilane highways.

Conclusions: Installation of directional median openings is a reasonable safety treatment at 4-leg access points because this access design has better safety performance than full median openings in terms of crash injury severity; in addition, it provides fewer restrictions on accessibility than closed medians. Other effective treatments include installing left-turn storage bays at median openings and increasing the width of shoulders and medians. Supplemental materials are available for this article.
