1. INTRODUCTION
Professor Yordphol Tanaboriboon was regarded the dynamic and active person in his
professional life and research activities. His motivation made very promising in his researchstudies where there are ample reflections of innovative studies and futuristic visions. He
passed away in June of 2006 when he was serving as Professor and Field Coordinator ofTransportation Engineering Program, under School of Engineering and Technology, Asian
Institute of Technology (AIT), Thailand. He was also the director of Asian Center forTransportation Studies (ACTS) and Thailand Accident Research Center (TARC); both locatedat AIT.

2. LIFE SPAN: EDUCATIONAL AND SERVICE LIFE
Yordphol Tanaboriboon received his bachelor and masters degree from Oklahoma State
University in the USA in 1973 and 1975 respectively. He was awarded doctoral degree in1979 from Virginia Polytechnic Institute and State University in the USA.
After being awarded the PhD degree from the USA in 1979, he started his professional careerin capacity building and research studies in various aspects of transportation engineering. He
bestowed his knowledge in different parts of the world by serving as a teacher in different
reputed alma maters. From 1979 to 1982 he worked as an Assistant Professor in King’s
Mongkut’s Institute of Technology in Thailand. Later, he served as a senior lecturer at
National University of Singapore from 1982 to 1986. Again, he joined to King Mongkut’s
Institute of Technology and worked as Associate Professor from 1986 to 1987. Then for the
first time he joined Asian Institute of Technology as Associate Professor and served from1987 to 1994. Then he went to anther overseas university – Tohoku University in Japan andworked there as Associate Professor from 1994 to 1995. Again he joined AIT and served as
Associate Professor from 1995 to 2000. Afterwards, he became Professor and continued his
professional career till 2006.
During his long professional career, Professor Yordphol contributed in different sectors oftransportation engineering both as a leading mentor and researcher. He realized the growing
need of public attention in road safety as early as in 1981 for Thailand as well in this region.
He first expressed his ever growing concern about the road safety situation in Thailand in theproceedings of the First Conference on the Study of Traffic Accidents in Thailand,
Chulalongkorn University, Bangkok in November, 1981 with the paper titled ‘Accident Studyon the Expressway’. Since then, road safety was regarded as one of the major concern but
neglected issues associated with public health, national economy, law enforcement and not tomention, transportation engineering. However, only a few researchers all over the world wereconcerned about this massive problem for the developing part of the world. With the passageof time, people forget those serious accidents brought under media coverage, but the problems
remain there. Understanding the gravity of the prevailing condition of the unattended
problem, Professor Yordphol brought it to the public attention through extensive researchstudies. Pioneered in this area of expertise in Thailand, he contributed to the Thai society
through his dedications in his professional career of exhaustive research activities, projects
and trainings in national and international arena.
During his service time he maintained some responsible affiliations with many promisingorganizations. This can be mentioned as follows:o Vice-President of the Eastern Asia Society for Transportation Studies (EASTS)
o Member of the Committee on Non-motorized and Related Issues in Developing
Countries, Transportation Research Board, National Research Council.
o Representative of the Transportation Research Board (TRB) to the Asian Institute ofTechnology (AIT)o Member of the American Society of Civil Engineers (ASCE)o Expert on Road Safety for United Nations (UN)o Road Safety Advisor for ADB on the ADB-ASEAN regional Safety Programo Senior Road Safety Auditor, Registered in Australia; audited 10 roads/intersections inThailand and 11 roads in Singaporeo Co-founder and Vice-President of Thailand Global Road Safety Partnership (TGRSP)o Member of the Engineering Institute of Thailand

4. CONCLUSIONS
Professor Yordphol’s research publications and projects and professional career encompassed
an important aspect of transportation engineering where his expertise and experience isreflected importantly in road safety, traffic engineering, public transportation andenvironmental aspect of transportation engineering. Maintaining a simultaneous interest indifferent branches of transportation, later he was involved more in road safety researches dueto the timely demand and perspective of Thai society.
Professor Yordphol is a researcher vested with futuristic vision. He is well known for his
thrive to utilize the tools of success of different disciplines in road safety. He introduced theuse of GIS and decision support system to improve road safety in Thailand. Following that
path, he applied data mining technology, which is a latest know-how used as a businessdecision making tool, in road safety to fathom the present road safety related problems in
Thailand with higher specificity and pragmatic applicability. In recent times, funded by theRoad Safety Foundation under the Department of Land Transport he was conducting researchstudies on the impact of drowsiness and fatigue of the drivers using driving simulator. This
research is also a unique of its kind in Thailand. For his dedication towards road safety
improvement in Thailand, he was awarded the Prince Michael International Road Safety
Award 2006.
Very sadly, a tour on Road Safety Training organized by Volvo Cars Safety Centre at
Gothenburg, Sweden where he went with a group of 16 students, staff, other official persons,he died by heart failure on Sunday 4 June, 2006. He is not present today, but his researchworks, his sincere dedication towards to his country and country fellow will remain evershining. He frequently motioned words towards his research colleagues were:“Working for road safety does NOT mean working under the ‘limelight’, even not being
paid attention by other people. DO NOT expect any reward from your service. Whatever you
can do to save even ONE LIFE then just DO IT.”
