Interest Areas

Dr. Hallmark has conducted a number of studies to evaluate the safety impacts of roadway countermeasures.  This includes evaluating driver behavior before and after installation of intersection collision warning systems, transverse rumble strip patterns at rural stop controlled intersections, stop sign beacons, and adding additional reflective treatment to stop sign posts at rural intersections.  Another project entailed evaluating truck behavior at reduced conflict intersections (RCI).  She has also conducted a number of studies which developed CMFs or crash prediction models for different roadway countermeasures including red light running cameras, edge line rumble strips, sequential dynamic chevrons, the Safety Edge, dynamic speed feedback signs on rural curves, paved shoulders, and high visibility enforcement.  She has also developed a number of guidebooks, including a toolbox on low-cost countermeasures to reduce lane departures, speed management in rural communities and high-to-low speed transition zones, countermeasures to reduce speeds in work zones, countermeasures to reduce speed on rural two-lane curves, and strategies to reduce red light running.
