Section 3: Relation to Other Documents
Anchor: #i1001002References to Other Documents
This handbook combines information contained in numerous other documents to assist in the design of freeway signing. In some cases, information from other documents is repeated in this handbook with appropriate citations to the source of the information. This is typically the case where information from several documents is combined in a section of the handbook. In other cases, this handbook refers the user to a specific document for guidance on sign design issues. This is typically the case where a single document contains the necessary design information.
Whenever practical, the handbook refers the reader to other documents so the handbook will not be out of date when these documents are revised. When information from other documents is repeated in the handbook, the reader should check to make sure the source document has not been revised.
Anchor: #i1001017Other TxDOT Documents
This handbook presents guidance information that may support or expand upon information contained in other TxDOT documents. The guidance contained in this handbook does not supersede standards, recommended practices, or requirements established by other TxDOT documents. The following documents also contain information related to the application, design, placement, installation, and maintenance of freeway signing:
Texas Manual on Uniform Traffic Control Devices (Texas MUTCD). The Texas MUTCD establishes practices for the selection, design, placement, operation, and maintenance of traffic control devices. The Texas MUTCD is the document that establishes the legal requirements for the selection, application, design, installation, and maintenance of traffic control devices. Many of the figures in this handbook contain cross-references to the Texas MUTCD to identify the need or application of a specific sign. When a figure contains a cross-reference to the Texas MUTCD, the user should refer to the indicated section of the Texas MUTCD to determine the appropriate application of or need for the sign. The 2003 edition of the Texas MUTCD (released in January 2003) was used in the preparation of this handbook. The 2006 Texas MUTCD was published after the completion of this handbook; however, an attempt was made to incorporate changes introduced in the 2006 Texas MUTCD into this handbook.
The Texas MUTCD is available on-line at http://www.txdot.gov/txdot_library/publications/tmutcd.htm.
Traffic Engineering Standard Sheets. The Traffic Engineering Standard Sheets developed by the Traffic Operations Division (TRF) contain additional guidance for the design, placement, and mounting of freeway guide signs. Where appropriate, figures in this handbook reference the standard sheets.
The Traffic Engineering Standard Sheets are available on-line at: http://www.dot.state.tx.us/insdtdot/orgchart/cmd/cserve/standard/toc.htm.

Standard Highway Sign Designs for Texas. The Standard Highway Sign Designs for Texas (Texas SHSD) presents the dimensions needed to fabricate individual standard signs. This document primarily addresses signs with a standard layout (such as regulatory and warning signs). Appendix F of the Texas SHSD includes information on the design of large freeway guide signs. That information has been incorporated into this handbook. Revision 4 (December 1998) of the Texas SHSD was used to prepare this handbook. The standard signs shown in the handbook figures are provided for illustrative purposes only. Every effort has been extended to ensure that the appearance of the standard signs in these figures is an accurate representation of the actual sign design. The Texas SHSD should be used to determine the design and layout of standard signs.
The Texas SHSD is available on-line at http://www.txdot.gov/txdot_library/publications/highway_signs.htm.
Signs and Marking Volume of the Traffic Operations Manual. The Signs and Marking Volume sets forth TxDOT standard practices and procedures regarding signs, markings, and other traffic control devices. This manual supplements the information contained in the Texas MUTCD. The November 1997 version of the Signing and Marking Volume (with the May 2000 revision of Chapter 10) was used to prepare this handbook.
Sign Crew Field Book. The Sign Crew Field Book provides field crews with information on the placement and installation of signs on conventional rural highways. The January 2000 version of the Sign Crew Field Book was used to prepare this handbook.
Anchor: #i1001090Other Non-TxDOT Documents
The following documents provide additional information that may be useful in the application, design, placement, or installation of freeway signs. Users should note that the guidance in these documents may not be consistent with TxDOT practice.
National Manual on Uniform Traffic Control Devices. At the time this handbook was prepared, the 2000 National MUTCD served as the national standard for traffic control devices. It is the basis for the 2003 Texas MUTCD. The Texas MUTCD is the official document for traffic control devices in Texas. There are differences between the National and Texas MUTCD. The 2003 Texas MUTCD was the version used to develop this handbook. However, an attempt was made to incorporate changes that appeared in the 2006 Texas MUTCD into this handbook.
The National MUTCD and related information are available on-line at: http://mutcd.fhwa.dot.gov.
Standard Highway Signs. Shortly after the publication of the 2000 National MUTCD, the FHWA published a new version of the national Standard Highway Signs (SHS). Both metric and English versions of the document are available. The metric version contains more information than the English version. The 2002 English version of the national SHS was used to prepare this handbook.
Both versions are available on-line at: http://mutcd.fhwa.dot.gov/ser-shs_millennium.htm.
