Dr. Chan received his Bachelor of Science degree in Mechanical Engineering in 1981 from National Taiwan University, and Master of Science in 1985 and Ph.D. in 1988 respectively, in Mechanical Engineering, from University of California at Berkeley.  He is a member of IEEE and SAE.  He is also a registered Professional Engineer in California.

 

Professional biography

 

In his early professional career, Dr. Chan gained in-depth experience in automotive occupant restraint systems when he worked in the airbag industry from 1988 to 1990, and since then he has further establish his expertise in that field.  Within the past decade, Dr. Chan has published extensively on the subject of automotive restraint systems.   From 1991 to 1994, he worked in the field of accident reconstruction.  In that capacity, he participated in the investigation of hundreds of real-world vehicle crashes.   Through his field experiences, he developed considerable insights into vehicle dynamics, collision characteristics, and driver behaviors for the evaluation of collisions under various roadway and driving conditions.   His knowledge in this subject area became indispensable later in many safety-related research projects. 

 

Chan joined PATH in 1994 and has since worked on a wide range of research projects spanning from sensing and control technologies to transportation safety evaluation and assessment.   He has participated significantly, either in a role of research contributor or a project lead, in many research projects at PATH.  He was the lead person representing PATH on the technology committee for the National Automated Highway System Consortium (NAHSC).  In recent years, he has been mostly active in the transit and safety research areas, such as Vehicular Collision Warning Systems and Intersection Decision Support systems. 

 

Chan also demonstrated his leadership in research management.  In 2002 and 2003, he was instrumental in the research project of Bus Rapid Transit (BRT) technology developments on experimental vehicles.  He led a team of researchers and engineers in implementing and demonstrating BRT technology in San Diego in August 2003, described in this linked article: http://www.path.berkeley.edu/PATH/Research/Featured/102803/san-diego.html.  The work subsequently won the "Best California Research Project/Facility" in the California Alliance for Advanced Transportation Systems (CAATS) Annual Meeting in December 2003, and the Best of ITS Research Award from the ITS America Annual Meeting in April 2004.

 

In 2008, for a Caltrans-sponsored research project, Safety Evaluation of HOV Facilities with Limited and Continuous Access, the graduate student, Kitae Jang, jointly advised by Chan and Dr. David Ragland, won the award of Excellence in Applied HOV Research from the Transportation Research Board’s HOV System Committee. The award is given to recognize groundbreaking, innovative and new ideas that have been incorporated into the advancement of the practice and field of HOV.

 

Currently, Chan is devoted to leading several externally funded projects in the area of ITS technologies and safety applications.  He is also the principal investigator for several highway network safety evaluation projects for studies on high-concentration collision locations, high-occupancy lanes, countermeasures and highway junctions. 

 

In the Spring Semester of 2006, he co-taught the class of Traffic Safety and Injury Prevention, a graduate course under the Transportation Program at Berkeley, with Professors Samer Madanat (currently the Director of Institute of Transportation Studies) and David Ragland (currently the Director of Traffic Safety Center).  He continued to be the co-instructor for the same class with Dr. Ragland in 2007.

 

From May 2006 to January 2007, Dr. Chan is serving as a Visiting Professor at the University of Tokyo in Japan, conducting collaborative studies with researchers at the Center for Collaborative Research, http://www.ccr.u-tokyo.ac.jp/index_e.html.

 

research activities

 

Chan’s research portfolio can be categorized into four main subject areas.

 

I. Transportation Safety

This subject area in recent years has been a topic of Chan’s research activities with fruitful results.  Through his participation in the Intersection Decision Support (IDS) and the Cooperative Intersection Collision Avoidance Systems (CICAS) projects, Chan has developed methodologies in collecting field observation studies and quantifying driver risk-taking behaviors.  In addition, Chan has been involved in research topics of rural highway safety and work zone safety, and the evaluation of automated speed enforcement systems.

 

II. Technologies for Intelligent Transportation Systems

Throughout his professional career, Chan has been involved in the evaluation and development of various technologies for transportation systems.  In recent years, he was active in pedestrian safety, in-vehicle driver assistance systems, and bus rapid transit.  Through the work in projects such as Transit Bus Collision Warning Systems, Transit Bus Rapid Transit, and Vehicular Platform for Pedestrian Detection, he has teamed up with many colleagues and published extensively.  In addition, with collaborative efforts with the University of New Hampshire, Chan has extended his research horizon to the integration of various technologies for on-board driver assistance systems and the evaluation of driver-vehicle interface.  Recently, Chan has also begun working jointly with governmental and industrial organizations on the subject of automated vehicle occupancy verification for the implementation of the operation of High-Occupancy Toll facilities.

 

III. Automotive Restraint Systems

In his early professional career, Chan gained in-depth experience in automotive occupant restraint systems when he worked in the airbag industry from 1988 to 1990, and since then he has further establish his expertise in that field.  Within the past decade, Chan has published extensively on the subject of automotive restraint systems with one book by Society of Automotive Engineers (SAE), one book articles, and 3 Journal papers in recent years.  He has also been invited to lecture for SAE, General Motor, For Motor, Honda America, American Automotive Medical Association, and American Bar Association.

 

IV. Highway Network Safety Evaluation

In the last several years, Chan has initiated an effort to develop a new specialty area of studies on highway network safety, in conjunction with joint projects with Dr. David Ragland, Director of Traffic Center of UC Berkeley.   In a span of 3 years, Chan and Dr. Ragland has jointly received grants of approximately $1 million to investigate the safety and traffic phenomena on California State Highway Systems and to establish systematic methodologies for safety performance assessment.  The research topics cover the methods of identifying High-Concentration Collision Locations, HOV facility safety performance and operation attributes, Highway ramps and junctions safety effects, wet weather collision causation, and roadway surface skid resistance data management.
