Chen-Fu Liao is educational systems manager for the Minnesota Traffic Observatory (MTO), previously known as Intelligent Transportation Systems (ITS) laboratory. He is responsible for developing ITS educational initiatives and interdisciplinary lab modules for undergraduate and graduate students at University of Minnesota.
After joining the ITS Laboratory in 2002, Liao began supporting simulator use and developing simulation-based modules for several transportation-related courses in the civil and mechanical engineering department. His development work includes a web-based traffic simulation module to help students better understand intersection signal timing and coordination, the Roadway Online Application for Design (ROAD) for learning geometry design and alignments, a real-time simulation framework for teaching vehicle guidance and control, and the Online Application of Signalized Intersection Simulation (OASIS) to help students better understand the logics of actuated signal timing and control.
Liao is currently working with professor Gary Davis on the second phase of a study of adaptive signal priority strategies for buses in Minneapolis. Wireless technology is proposed to provide communication between buses and intersection signal controller for adaptive signal priority for transit. He is also a member of the Access to Destinations Study research team, supporting non-auto mode studies with Kevin Krizek and Ahmed El-Geneidy. Mr. Liao will be working with Prof. Liu and Levinson for a Simulating Transportation for Realistic Engineering Education and Training (STREET) project recently funded by National Science Foundation (NSF). The focus of the STREET proposal is to develop and fine-tune a suite of simulation programs that can be easily incorporated in the undergraduate courses. A full spectrum of simulation modules, which will cover all major components of introductory course and its extension elective courses, will also be developed.
Liao is experienced in embedded system computing, database analysis and management, wireless communications, ITS systems, traffic simulation and 3D traffic simulation & visualization. He developed a 3D traffic simulation model and database available on the Internet and also utilized in the Minnesota Traffic Observatory’s CAVE virtual reality environment for traffic study. It can also be included in a driving simulator for human factor study. He also worked on DGPS (Differential GPS) analysis and evaluation while working as research assistant at University of Minnesota from 1993 to 1996.
