Faculty Fellow Diana Bowman co-authored a recently published study on the impact of intersection design on driver safety. The study, Evaluation of alternative intersection treatments at rural crossroads using simulation software, was published in Traffic Injury Prevention.
The study used crash simulations to look at the effect of different intersection layouts, technologies, and traffic policies on rural roads. The design of intersections on rural roads make them disproportionately likely sites for injuries and fatalities, even though they see far less traffic than intersections in cities. The authors determined that improvements in intersection design and policy could save lives and prevent injuries.
