Project 0-4586

Revision of AASHTO Fatigue Design Loadings for Signs, Luminaires, and Traffic Signals, for Use in Texas

cantilever traffic signals

Provisions for fatigue design in Section 11 of the Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals issued in 2001 made it difficult to find economical AASHTO-compliant design solutions for cantilevered traffic signal structures. This research project addressed important questions by means of full-scale controlled and field tests on traffic signal structures. Fundamentally, the objective of this project was to re-evaluate the fatigue design loads for traffic signal structures in the AASHTO specifications
