Roadside Design Guide 2006, with Updated Chapter 6

Description

The Roadside Design Guide is developed and maintained by the AASHTO Subcommittee on Design, Technical Committee for Roadside Safety. The guide presents a synthesis of current information and operating practices related to roadside safety and is written in both metric and U.S. Customary units. This 2006 Edition of the guide supersedes the 1996 AASHTO publication of the same name and includes an update to Chapter 6, “Median Barriers,” which replaces Chapter 6 of the 2002 Edition. In this guide, the roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder of the roadway itself, if any. Consequently, roadside delineation, shoulder surface treatments, and similar on roadway safety features are not extensively discussed. While it is a readily accepted fact that safety can best be served by keeping motorists on the road, the focus of the guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road.
