Visualisation |
When designing a timetable, some questions may come up:
It is not so easy to answer all questions by using the time distance diagram only. In some cases
you must have some experiences with the interpretation of these diagrams and furthermore in some cases
you need the details of the underlying railway system.
Not all intersections of two timetable lines in a time distance diagramm are collisions. Often it
depends on the implementation of the belonging track section. In order to decide about if an
intersection is a collision or not, you have to check the direction of the trains and the track section
(one rail for both direction or one rail for each direction). Depending on these facts it could be a
collision, the two trains
could drive one after another in a short distance or they drive path to one another.
By means of this training module you can execute a developed time distance diagram example
and observe the actions via an adequate visualisation.
After the start of the visualisation, train icons move along the rails of the map according
to the specified timetables in the diagram (see Figure 21).
During the execution, the time distance diagram and the map are not editable. Therefore, the
function items for e.g. moving or adding timetables, stations or rails are disabled.
After the termination of the execution these items will be enabled again.

The visualisation bases on time steps.
These time steps are the elementary time unit. During the definition of the diagram time range
you can define the time step wide (see Set Time Range).
There you can also determinate if the time steps consist of a sum of abstract time units or
an appointed
time measurement of seconds and minutes, respectively.
The visualisation shows after each time step the current positions of the trains on the map.
In addition a grey progress bar on the diagram shows the elapsed time (see Figure 21).
Within this training module there are two different kind of visualisation flows. You have the
choice between
a stepwise or continuous visualisation. The stepwise visualisation base on the time steps
and stops after each time step.
In the following subsection you can learn how you can start and control the visualisation in this
training module.
