Preface
This Policy was developed as part of the continuing work of the Standing Committee on
Highways. The Committee, then titled the Committee on Planning and Design Policies, was
established in 1937 to formulate and recommend highway engineering policies. This Committee
has developed A Policy on Geometric Design of Rural Highways, 1954 and 1965 editions; A
Policy on Arterial Highways in Urban Areas, 1957; A Policy on Design of Urban Highways and
Arterial Streets, 1973; Geometric Design Standards for Highways Other Than Freeways, 1969;
A Policy on Geometric Design of Highways and Streets, 1984, 1990, and 1994; A Policy on
Design Standards—Interstate System, 1956, 1967, and 1991; and a number of other AASHO and
AASHTO policy and “guide” publications.
An AASHTO publication is typically developed through the following steps: (1) The
Committee selects subjects and broad outlines of material to be covered. (2) The appropriate
subcommittee and its task forces, in this case, the Subcommittee on Design and its Task Force on
Geometric Design, assemble and analyze relevant data and prepare a tentative draft. Working
meetings are held and revised drafts are prepared, as necessary, and reviewed by the
Subcommittee, until agreement is reached. (3) The manuscript is then submitted for approval by
the Standing Committee on Highways and then the Executive Committee. Standards and policies
must be adopted by a two-thirds vote by the Member Departments before publication. During the
developmental process, comments are sought and considered from all the states, the Federal
Highway Administration, and representatives of the American Public Works Association, the
National Association of County Engineers, the National League of Cities, and other interested
parties.
