Abstract
The trend towards higher speed, more frequent traffic and many traffic operators
requires new strategies and solutions for efficient train traffic control and
utilization of track capacity. Operative control is today focused on controlling
the infrastructure. In earlier research we have shifted the control paradigm from
today’s technology oriented into a more traffic oriented one. This is done by
real-time re-planning. The continuously updated traffic plan is normally executed
by automated systems. After tests and evaluation in a simulated laboratory
environment, the Swedish Rail Administration (Banverket) decided to develop
and deploy an operative system to be installed at a traffic control centre. This
system, called STEG, implements the main research results. Features of the new
system are a dynamic planning view in form of a time-distance graph, decision
support that helps the controller to identify disturbances and conflicts and
automatic systems for execution of the traffic plan. The traffic controller can
re-plan traffic (time aspects, track usage) via direct manipulation of the graph
lines in the interface. Track maintenance and other activities can also be planned.
The system automatically calculates all consequences of the changes and shows
the effects on all trains within the actual time-distance space. A very careful
process has been used to go from research results and prototypes to a fully
operational system. The process has been very user centred and numerous
iterations have been performed. Through this elaborate work, we have been able
to ensure that the intentions of the prototypes have been correctly implemented
in the final product.
