Highway Design Manual
Announcements of Additions and Revisions.
Additions, revisions and errata corrections to the HDM are announced by Engineering Bulletins (EBs). EBs can be found by using the EIEB application.
Downloads:
The entire HDM may be downloaded, free of charge, by clicking on the individual chapter links above. Each .pdf file includes all the graphics pertinent to the individual chapters. To read or download the HDM files you need the Adobe. Acrobat. Reader, version 4.0 or higher installed on your computer.
Zweck:
The primary functions of the Highway Design Manual (HDM) are to: (1) provide design criteria, requirements, and guidance on highway design methods and policies which are as current as practicable, and (2) assure uniformity in the application of design practices throughout the New York State Department of Transportation consistent with the collective experience of the Department of Transportation, the American Association of State Highway and Transportation Officials, and the Federal Highway Administration. The Highway Design Manual, originally issued in July 1972 and March 1973, has been revised over 70 times. Old versions are available through the link to the HDM Revision Log.
Context:
The HDM is the primary source of guidance for detailed highway design. It is also frequently referred to in the scoping stage and preliminary design phase and occasionally referred to for some construction issues. The context for the HDM includes the following points.
- Along with the HDM, the processes that should be followed and studies that should be performed are covered in documents such as the Project Development Manual (formerly the Scoping Procedure Manual and the Design Procedure Manual) and the Environmental Procedures Manual.
- Issuing an HDM is a significant undertaking. Consequently, some changes to the design guidance may be issued via Engineering Instructions and may subsequently be incorporated into an HDM revision. Designers are advised to check not only the most recent revision of the relevant HDM chapter, but also the subsequent Engineering Instructions that may relate to the subject of interest in order to determine the current guidance on a given subject.
- The HDM is the primary design guidance used by NYSDOT designers for highways they are responsible for designing. It generally does not govern the design work performed by county and municipal designers, unless they choose to adopt it as their design guidance.
- Additional design guidance is provided in a number of national publications issued by the American Association of State Highway and Transportation Organizations (AASHTO) and others. However, while the HDM is generally aligned with the guidance in those documents and occasionally refers to them, where there is differing guidance, the HDM should be considered the governing document.
