Abstract:

The purpose of this project is to conduct a structural assessment of Maryland sign structures based on the American Association of State Highway and Transportation Officials (AASHTO) Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, 6th edition (AASHTO LTS-6) strength and fatigue criteria, using these criteria and methods to study and evaluate the Maryland Department of Transportation’s State Highway Administration sign structure database and taking samples from the selected categories. The research developed a methodology for analyzing sampled sign structures, running selected sampled cases and verifying structural results. After evaluating sampled sign structures, a ranking category was established which led to prioritizing the whole population based on the evaluation. Finally, all information from the research was summarized and the findings were reported.
