Manual: Traffic Signals Manual

Effective Date: April 01, 2011


The purpose of this manual notice is to advise users of the Traffic Signals Manual that the manual has been revised to include new and updated technical information on the installation of accessible pedestrian signals and uninterruptible power systems/battery backup systems at signalized intersections.


The contents of the Traffic Signals Manual have changed as follows:

Added Section 4 to Chapter 5 of the manual to provide guidelines for the installation of accessible pedestrian signalls at signalized intersections. These guidelines are consistent with the Draft Proposed Right-of-Way Accessibility Guidelines developed by the United States Access Board.

Added Section 5 to Chapter 5 of the manual to provide Guidelines for the Installation of Uninterruptible Power Systems/Battery Backup Systems for signalized intersections.


The Traffic Operations Division (TRF) worked with the districts in revising the material that went into this revision. The TxDOT Office of General Counsel and Audit Office reviewed the two new sections of this manual and all comments were considered in the final revision.


Address questions concerning content of the revised manual to:

Henry Wickes, P.E.
