It was my great pleasure to host Bryan Reimer at UNH. Bryan is Research Scientist at the MIT Age Lab as well as Associate Director of the New England University Transportation Center. His research focuses on the measurement and understanding of human behavior in dynamic environments, such as in cars.

Bryan spent time in the Project54 lab discussing various aspects of driving simulator and field studies. He then gave a thought-provoking talk reviewing results from multiple studies exploring driver workload and distraction. I expecially enjoyed his discussion of physiological measures that can be used to estimate workload. E.g. Bryan has found that heart rate is a robust estimate of workload and is often more useful than the often-used measure of heart rate variability. Bryan also discussed work on validating driving simulator results through field studies. His data indicate that driving simulator results can be used to predict relative changes in workload measures under different situations in real-life driving. However, the actual values of the measures collected in simulator and field studies often differ significantly.
