The purpose of this document is to meet the need for National Park Service road design standards that will accommodate current or planned park road use, while continuing to preserve the natural and cultural values of National Park System areas; to address the requirements of Standard 12 of the Federal Highway Safety Program Standards (23 CFR 1230; 23 U.S.C. 402); and to provide design guidance for projects under the Federal Lands Highways Program for Park Roads and Parkways (P.L. 97-424; 23 U.S.C. 204) compatible with Chapter 3(C)(1) of the Federal Highway Administration (FHWA) Direct Federal Manual. This document is also intended as a definitive guide for managers, planners and designers involved in the planning, design and construction of park roads.
This report summarizes a recent assessment of the Safety Edge SM that was performed to determine the feasibility of using this pavement edge treatment...
