1: Overview
The
Texas Manual on Uniform Traffic
Control Devices
(Texas MUTCD), TxDOT’s Traffic Engineering
Standard Sheets, Standard Highway Sign Designs for
Texas
, and Traffic Operations Manual:
Signs and Markings Volume
contain information on how
to design freeway guide signs in Texas. However, in many cases,
detailed guidance on how to design and lay out a guide sign is scattered
among these documents. The purpose of this chapter is to provide
guidance and references for the basic design and layout of freeway
guide signs.Basic freeway guide signs are standardized with specific design
details given in the
Standard Highway Sign Designs
for Texas
. These signs include Exit Gore signs, Exit
and Guide Sign Number panels, Rest Area and Picnic Area signs, Left
Exit and Exit Only panels, and various other freeway signs. However,
Advance Guide and Exit Direction signs need to be designed separately
because of the variability in message, sign size, and location.This chapter contains details on the types of freeway guide
sign design elements, including abbreviations, Route signs, arrows,
and sign panels. This information is followed by general guidance regarding
sign lettering and sign layout.
Information provided in this chapter primarily comes from
the Texas MUTCD, Traffic Engineering Standard Sheets,
Standard
Highway Sign Designs for Texas
, Traffic
Operations Manual: Signs and Markings Volume
, and
the National Manual on Uniform Traffic Control Devices (National MUTCD).
Specific design guidance is illustrated or referenced to the appropriate
documents for additional information.
