TRL is one of the largest and most comprehensive independent centres for the study of road
transport in the world. TRL employs around 300 technical specialists, among them mathematicians,
physicists, economists, psychologists, engineers, geologists, computer experts, statisticians.
Facilities include a state of the art driving simulator, a new indoor impact test facility, a 3.8km
test track, a separate self-contained road network, a structures hall, an indoor facility that can
dynamically test roads and advanced computer programs which are used to develop sophisticated
traffic control systems. TRL has developed close working links with many other international
transport centres and provides expert advice to the EU and other international bodies. TRL operates
a quality management system that is certificated as complying with BS EN ISO 9001.
Dr.
Rob Tunbridge received his PhD in Physical Chemistry from the University of London in 1974. He

fatigue in 1995, and as member of the Standing Committee on Road Accident Statistics for
re-establishing the collection of accident contributory factors on a standardised basis. He was
responsible for both the first UK epidemiological study of drugs and driving in 1985, while at TRL,
and the current follow up study. He was a member of the very influential Inter-Departmental Working
Group on 'Sensible Drinking' which reported in 1995 and is a member of the International Council on

Mr. Andrew Parkes received his M.Sc. (Eng.) in Work Design and Ergonomics from the
University of Birmingham, UK in 1983. Until 1996, he was a Senior Research Fellow at Loughborough
University of Technology (LUT) and the Principal Scientist at HUSAT (Human Sciences and Advanced
Technology) Research Institute. He is currently Head of Driving Simulation Centre at TRL. His
research interests include driver impairment, training, visual behaviour, evaluation methodologies
and design standards. He is a member of the American Psychological Association, the United Kingdom
Ergonomics Society, the Human Factors and Ergonomics Society, and the International Association of
Applied Psychology. He has a substantive involvement in various UK, EC and International Standard
Committees (e.g., BSI EEL/37/10, CEN TC278/WG10, ISO TC22/SC13/WG8 and 9).
Mr. Barry
Sexton received his MSc. in Statistics and Operation Research from City University in 1972. He
has been a Charted Statician with the Royal Statistical Society since 1992. Mr. Sexton is a is
currently employed as a Statistical Consultant, with a research and project management capacity as
well as managing the driving simulator. His position requires advising and liaison with clients,
