Research in this specialty area focuses on the safety and sustainability
of transportation infrastructure systems. Specific research areas in
transportation safety include work zone safety, effectiveness of traffic
control devices, safety and mobility of older persons, and surrogate
measures of accident exposure.
Current research in pavement engineering
includes the development of asphalt and concrete mechanistic-empirical
pavement response and performance models, material characterization
using non-destructive field and laboratory testing, advanced
cost-effective pavement preservation methodologies, rapid construction
quality assurance technologies, innovative pavement management
strategies, dynamic vehicle-pavement interaction, and modeling of
vehicle operating costs.
