This book contains selected papers from the presentations given at the
7th EURO-Working Group Meeting on 'Iransportation, which took place at
the Helsinki University of Technology (HUT), Finland, during August 2-4,
1999. Altogether 31 presentations were given and 14 full papers have
been selected in this publication through a peer review process
coordinated by the editors. The papers in this book cover a wide range
of transportation problems from the simulation of railway traffic to
optimum congestion tolling and mode choice modeling with stated
preference data. In general, the variety of papers clearly demonstrates
the wide areas of interest of people who are involved in the research of
transportation systems and their operation. They as well demonstrate the
importance and possibilities of modeling and theoretical approaches in
the analysis of transportation systems and problem solving. Most of the
papers are purely theoretical in nature, that is, they present a
theoretical model with only a hypothetical example of applica- tion.
There are, however, some papers, which are closer to the practice or
describe applications of and give interesting results of studies made by
known methodologies. It is especially noteworthy, that half of the
accepted papers deal with planning and operation of public transport.
