Chen-Fu Liao's research focuses on using Intelligent Transportation Systems (ITS) technologies to assist people with vision impairment in finding their way. Dr. Liao recently developed a mobile accessible pedestrian signal (MAPS) system to assist the visually impaired with crossing streets at signalized intersections. He is also working on using assistive technologies to help the visually impaired safely navigate work zones and in GPS unfriendly environments. His other research activities include connected vehicles, incident decision support systems, database management and data mining, freight performance measures, and developing undergraduate and graduate curriculum tools to support transportation education and training.
Transportation research at the University of Minnesota covers the spectrum from basic to applied research, drawing on the many transportation-related disciplines within the University. The Center actively supports the formation of multidisciplinary research teams.
