Hi

I'm writing an import filter in RailML as part of my diploma theses and here the following question came up:

What is the meaning of the attributes meanDelay and meanDelayDeparture for <entry> or what is the reason they are in the scheme?

If you do have planned data <train type=planned> you won't have this information available.
If you do have actual data (measured) you need this data day-by-day and had to define a new<train> for each day.
So I can't think about a case where these attributes would be helpful

or where I'm wrong?

Thanks, Lukas

The meanDelay attribute was integrated into the scheme because it can be
a useful information for simulation systems. You can have all your
planned data for a given (or future) timetable but beside that you can
have real delay date (statistics) evaluated by a dispatching system or
train control system (e.g. over the last time period). A simulation then
can reproduce the same pattern of failures and delays in a new timetable
and check if the timetable is stable and robust.


Best regards

Dani
