Hui has four years of experience in traffic flow models, data analysis, travel demand model application, traffic microsimulation, and traffic emission analysis. As an intern at OKI Regional Council of Governments, she developed data processing systems using SQL Server for pedestrian and bicycle counts. During her Ph.D. study, Hui developed algorithms and systems for radar data to automatically extract lane boundaries, vehicle trajectories, and traffic information to validate fundamental diagrams. She also participated in an environmental research project supported by the EPA and analyzed the impact of traffic control measures on emission rates from a microscopic perspective. Hui has expertise in various transportation analysis software, such as VISSIM, VISUM, ArcGIS, HCS, CUBE, and AutoCAD. She is also good at programming languages, including C#, SQL Server, R, and VB for data analysis and research purposes.
