The Master's Programme

On short notice, people at the Linköping University (LiU) Institute of Technology prepared for another international master's programme. This new education in Traffic Environment and Safety Management is offered at Campus Norrköping, recently established and very popular among students. The first group of candidates arrived on 3 September 1998. Some of the programme outline is based on demands from participants in shorter international traffic safety courses at the Swedish Road and Transport Research Institute (VTI).

The Vehicle Safety Systems Course

While still working full-time as a free-lance scientist in my company StOP close to Linköping, I (Lennart Strandberg) was asked to contribute to the programme by arranging a course in Vehicle Safety Systems. Fortunately, I could return on half-time to my position as a professor in accident research at the National Institute of Working Life (NIWL), kindly allowing me to spend time with the LiU for the Master's Programme. Thanks also to the Swedish vehicle industry, very qualified lecturers and relevant contents have been proposed from the first outlines of the course program below.



Welcome to students

The first candidate meeting took place on 3 September 1998 at Campus Norrköping. If you are one of our foreign guests, I hope you will find yourself at home in Sweden and enjoy our new Campus. On your request October 19, some everyday life hints to foreigners in Sweden may be found below.

Since my vehicle course will not start until in late November, you may want to check out some web-pages on vehicle safety in advance. In the beginning, I intend to extend the list of links quite often, so come back soon for new views.
Now, all vehicle related links are on the same page below, to make it easier for you to download them.
Comments on
literature will be particularly valuable, if they are submitted early.

When we have sorted things out in Norrköping, professional web-makers may take over with forms etc, where you may submit additional links and comments. We may also arrange the stuff in frames to simplify browsing.

Good Luck!
Web-page for expert communication

Since the NIWL office is in the Stockholm area 200km north of Linköping, I use the StOP local resources and my company's Internet domain to simplify communication between experts who may contribute lectures, study visits, literature, experimental support, etc. To coordinate different parts of the course, people involved are encouraged to contact each other directly through the list of addressees, which may be extended below with individual names and Email addresses after approval.

ORGANISATION. Structure & Period.

Credits: 5-8 points.

Lectures Seminars Laboratories Company visits (Field tests: 1 week).

Swedish vehicle manufacturers and the Swedish Motor Vehicle Inspection Company contribute substantially to this course with lecturers, study visits and laboratory lessons.

If possible, field measurements and driving tests will be carried out with instrumented cars (probably in the early 1999). Candidates participate in experimental planning, will get hands-on experience of data acquisition and may be occupants or drivers in the tests. Evaluation is included in the course program and takes place after returning to Norrköping.

Course literature to be announced. Compendium, study questions and answers, lecture notes.

    Literature options. Preliminary list.

      Since the course does not start until in November, people (you) may suggest literature which is more suitable than the following proposals (under consideration in early September 1998). Due to the tight schedule, I have not yet had time to check out more recent editions. Please, excuse me if some of the listed textbooks below are unavailable on the market.

    Gillespie, Thomas D. (1992). Fundamentals of Vehicle Dynamics.
    Requested by ITN in early October
    SAE Order No. R-114, Society of Automotive Engineers, Inc. (495pages) ISBN 1-5601-199-9.
    This textbook covers important areas of vehicle dynamics from the accident avoidance perspective. However, its numeric examples use units such as inch, lb, degrees, etc and not metric units. Its cartesian coordinate system has the z-axis pointing downwards, instead of upwards like in the vehicle models common in Swedish education and research. This may be confusing, but will also give the students experience in conversions, which they may encounter in forthcoming situations.

    Textbooks in German only

    Metric units, upwards z-axis and 100 pages with test and measurement technology make the following textbook a valuable supplement.
    Zomotor, Adam (1987). Fahrwerktechnik: Fahrverhalten.
    Vogel Buchverlag (382 Seiten) ISBN 3-8023-0774-7.

    A very useful handbook (not only for accident investigators) which has been referred to on the web in the late 90's:
    Burg, Heinz & Hartmut Rau (1981). Handbuch der Verkehrsunfallrekonstruktion.
    Verlag INFORMATION Ambs GmbH (838 Seiten) ISBN 3 88550 020 5.

    Collision mechanics is not covered by the Gillespie book above.
    Therefore, the following textbook may be needed, too.

    Macmillan, R.H. (1983). Dynamics of vehicle collisions.
    Requested by ITN in early October
    Proceedings of the International Association for Vehicle Design. SP5. (141pages) ISBN 0 907776 07 8.

    Robert Bosch GmbH (199?). Automotive Handbook.
    SAE publication in German, French and English from the Bosch company. ISBN 0-89883-518-6.
    Suggested by Chief Engineer Mats Wallin at MTC Inc. for his lectures on Environmental effects.

    Doebelin, Ernest O. (1980). System Modeling and Response. Theoretical and Experimental Approaches.
    John Wiley & Sons, Inc. (587pages) ISBN 0-471-03211-5.

    Jones, Ian S. (1976). The Effect of Vehicle Characteristics on Road Accidents.
    Pergamon Press. (219pages) ISBN 0-08-018963-6.

    Schlesselman, James J. (1982). Case-Control Studies. Design, Conduct, Analysis.
    Oxford University Press, Inc. (354pages) ISBN 0-19-502933-X.
    This epidemiological approach has been superior in past investigations assessing relative risk factors in vehicles (and drivers). If road and traffic factors interact, it may be necessary to neutralise them by pairing case and control vehicles (drivers) with respect to road and traffic conditions. See the reports below by Jones (1987). The method will also open up a different perspective on the concept of exposure, which may reveal new possibilities of safety improvements in drivers, vehicles and their interaction.
    The book may be covered by the October course in Traffic Statistics, given by Mats Wiklund at the VTI.

    Leasure, Jr. William A. & Williams, Jr. Sidney F. (1989). Antilock Systems for Air-Braked Vehicles.

      Certain parts of numerous reports will be dealt with in detail.
      Copies may be given to the students by the
      lecturers, who are requested to provide the course secretariat with two reference copies (in advance, please).
