Roadside Design Guide
This Roadside Design Guide was developed by the American Association of State Highway and Transportation Officials (AASHTO) Subcommittee on Design through the Technical Committee for Roadside Safety (TCRS) under the chairmanship of Keith Cota, P.E.
This book presents a synthesis of current information and operating practices related to roadside safety and is written in dual units— metric and U.S. Customary. This edition supersedes the 2006 AASHTO publication, which included the update of the Median chapter.
The roadside is defined as that area beyond the traveled way (i.e., driving lanes) and the shoulder (if any) of the roadway itself. Con- sequently, roadside delineation, shoulder surface treatments, and similar on-roadway safety features are not extensively discussed.
Although safety can best be served by keeping motorists on the road, the focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver does run off the road.
