Forecast

Forecast calculates arrivals.

With PSItraffic you can react to forecasted conflicts and delays at an early time
and thus ensure smooth operations. 

The forecasting module calculates the timetable from the schedule data and the locations drawn from the tracking module. From this, it calculates the arrivals at the following stations.

If journeys have already been linked in the schedule to journey courses, the forecast is also made for subsequent trips. Parameters such as turnaround times and rest periods are included in the forecast calculation.

The simulation of other itineraries is performed using a block-wise consideration of movements, i.e. a forecast is generated for the passing of subsequent track sections for each train using the method described above. Continuous checks are made whether the required routes will be available on time, or whether they are available or will be blocked by the pre-set routes of other trains. This results in forecasted blocking time stairways for each train, which are checked for overlap.

In case of conflicts, the forecast is first adjusted. In case of delays, stopping and turnaround times are shortened, as long as this is possible while still taking into account the specified minimum times for stopping and turning and connections that must be kept. The forecast for the length of platform stops is initially created using the stop times from the schedule.
