RESEARCH INTERESTS

Driver behaviors. Much is assumed about rational and predictable decision making in traffic; much less is known about actual behaviors that are irrational, are known to exist, but are not represented in existing gap-acceptance or car-following models.

Roundabout simulation and modeling. Calibration and validation of models based on data collected in the United States is lacking. As a result, there exist planning barriers for more widespread implementation of roundabouts which may benefit safety, efficiency, and emissions in the transportation system.

Sustainable transportation planning and GIS spatial analysis. Using disaggregate data for the planning of transportation systems and finding unique ways to leverage the use of large, existing, and publicly-available datasets for issues relating to livability, accessibility, and mobility in rural and small-urban areas.
