• This article includes a brief
introduction to a simulation project
carried through at the University of Gothenburg,
Department of Business Administration.
The outcome of the project
has partly been published in a technical report now available (Larsson and
Lundin 1971). i
The purpose of the project was to increase our knowledge of model building
and the application of digital simulation techniques.
The technical report
is only part of a dissertation (for the Swedish licentiate degree) and thus
include s :
o an outline of a systems approach to urban traffic planning and control,
o an introduction to unique model building technique that may appear
useful in other applications, and
o a detailed description of a digital simulation model feasible to use
for key descriptions concerning urban traffic control systems.
The report does not include any survey or critical review of methodological
problems such as validation and experimental design problems which however
were treated to some extent with the project. ~
General Characteristics of the Model
The system considered in the study may be described as a multistation,
multichannel queueing system with dynamic and stochastic properties.
The simulation model (the computer model) was given a modular design in
to facilitate easy adaption to various street networks and modes of
traffic control as well as feasible representation
the system (deterministic
- various stochastic distributions),

traffic studies, starting with Gerlough~s work at UCLA in 1955.
