AASHTO RAC MEMBER SURVEY RESULTS

Title: Design of Structural Supports for Highway Signs, Luminaires, and Traffic Signals

Survey Details/Results: The Alaska Department of Transportation & Public Facilities conducted this survey in April 2008. The intent was to determine what design procedures are in use for designing structural supports for highway signs, luminaires, and traffic signals. The specific area of interest was design parameters relating to fatigue. Respondents were asked the following questions:

1. Has your state adopted the 2001 AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals?

2a. What fatigue category (I, II, or III) have you selected?

2b. Have you adopted Chapter 11?

2c. Have you taken exception to any other part of the standard? If so, which?

3. Do all regions/districts within your state use the same design guideline for traffic signal poles?

4. Is a specific pole modeling software program used in the design of traffic signal poles? If so, could those models be shared?

5. Are standardized pole drawings available on a website? If so, please provide a url.

Of the states/provinces surveyed, 22 responded. Most of the survey respondents indicated that they have adopted, to some extent, the 2001 AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminairs and Traffic Signals.
