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.
Liao received his bachelor's degree in mechanical engineering from National Chunghsing University in Taiwan. He earned both MS and PhD degrees in mechanical engineering from the University of Minnesota. Before joining the University of Minnesota, he worked as a product developing engineer specializing in pneumatic linear positioning systems at Tol-O-Matic, Inc. He is a member of the Institute of Electrical and Electronics Engineers (IEEE), Transportation Research Board (TRB), and the Institute of Navigation (ION).
