Structural research at TTI covers infrastructure and constructed facilities as well as the design and use of roadside safety structures. Researchers at TTI develop innovative methods to analyze, design, construct, maintain, and manage large structural components of the nation's transportation network. In addition, TTI research has resulted in products that have been deployed nationwide to improve roadway safety and enhance travel—such as crash cushions, breakaway sign supports, guardrails and treatments, barrier systems, and improved pavements and materials.
TTI's structural engineers and researchers study supporting structures fundamental to transportation, focusing on design and analysis of constructed facilities, dynamic loading and structural behavior, modeling and analysis, natural hazards, probabilistic and stochastic modeling, and rehabilitation and renewal of infrastructure. In addition to other structural topics, TTI research encompasses the design and evaluation of bridges along with studies of expansive soils, scour and erosion, construction quality control, and seafloor characteristics.
TTI's roadside safety experts have extensive experience in finite element analysis, simulation, structure analysis and design, vehicle dynamics, and safety. Research on roadside devices encompasses the influence of roadside geometric features such as driveways, slopes, ditches, shoulders, and medians. Results produce real-world guidance that enhances overall transportation safety.
