Modellering van een openbaar vervoernetwerk.
Report 92.3.LT.3070, Transport Technology, Logistic Engineering.
This report summarizes subjects regarding public transport. Design,
control and recent developments of public transport will be discussed.
When designing public transport networks the demand for transport, the
streetnetwork and the budget are known. The question rises what routes the
transportlines have to follow and what frequencies they should have for an
optimal transport network. Objectfunctions, constraints and control
variables will be used to solve such problems. A lot of algorithms are
available in the form of models for the design of public transport
Models, which determine the demand for public transport, create
a possible set of routes, optimize or evaluate.
Using the models a planner designs a network. Not only these models
contribute to the design, also the specialized insight of the planner and
other factors define the final network.
The quality of a transport network cannot be guaranteed by a good design.
Especially the execution of service is of great importance; this concerns
the operational control. Some definitions at operational control: speed,
punctuality/regularity, synchronization and practicability.
Datacollection systems and processing systems have to provide data and
information, which are necessary for control, expansion or adjustment of
the transport network.
The public transport compete with the car transport. Consumers like to be
picked up at home and to be dropped at their destinations. In this field
developments are in the form of train-, region- and expressbustaxis.
High frequency transport will be provided by automatic transport systems.
Examples are mini-undergrounds, suspension-railways and magnetic-railways.
At Delft University of Technology specific knowledge about transport networks
is available at the department Traffic and Public Transport at the faculty of
All aspects, discussed before, will be reflected upon in this report and
are the result of a study of literature, executed in accordance with the
fourth years essay.
