Human Factors Group

Description

This program serves as a resource to all of TTI by providing expertise on human behavior. Our research staff, trained as experimental psychologists and industrial engineers, is active in a wide variety of safety related projects. Topics include visibility and comprehension of traffic control devices, driver distraction, driver response to roadway geometric design, the effects of fatigue on dredge operators and locomotive crews, driver training, and traffic safety statistical analyses. The group makes use of the TTI driving simulator, instrumented vehicle, and the closed-course driving ranges at the Riverside campus and Pecos to conduct its empirical research. Other projects involve survey, focus group and other laboratory data collection methods, and behavioral analysis. Consulting in the areas of visual perception and cognition, driver behavior data collection methodology, and experimental design is provided to research projects across all parts of TTI.
