Over the years, ATSSA has demonstrated that the installation or upgrade of roadway safety features – many of them available at low-cost – can provide immediate and substantial safety benefits for all. The expertise, knowledge and experience of ATSSA members are in the development and installation of traffic control devices and roadside safety features that make the roadway safer and more forgiving for all users of the roadway system. This document (in large part) focuses on the policies and practices needed to move America Toward Zero Deaths (TZD).

The Federal Highway Administration (FHWA) is improving its process for issuing Federal-aid eligibility letters for roadside safety hardware systems.

The National Cooperative Highway Research Board provided a review and update of the American Association of State Highway Transportation Officals' "Roadside Design Guide."

The FHWA is exploring several potential options for reviewing, evaluting, and accepting the results of crash testing of roadside safety hardware that is intended to be used on the National Highway System (NHS). The options are for discussion only.
