One of the most important and most challenging aspects of highway engineering is designing to enhance life safety. This chapter focuses on roadside safety, which encompasses the safety of vehicles that leave the roadway and shoulder.
This material is based largely on the publication of the American Association of State Highway and Transportation Officials (AASHTO), Roadside Design Guide (2002, 2006), which was developed by the AASHTO Subcommittee on Design, Task Force for Roadside Safety, currently under the chairmanship of Keith A. Cota. Made up of about 20 highway engineers with diverse experience, the task force maintains and updates a synthesis of current information and operating practices to serve as a comprehensive guide to individuals and agencies in developing standards and policies. Their contribution to promoting highway safety is gratefully acknowledged.
