Forecast

Forecast - what is is?

In acumen parlance, the Forecast is a service which runs within the application with the sole purpose of agregating numerous sources of information and extrapolate this against a train service schedule; the net result is a forecast of a train service schedule that reflects all known conditions and one which has a high degree of accuracy.

Items the acumen uses to formulate the forecast are:

• Current reported position and any lateness;
• Any overdue reports;
• Activity times provided in the schedule and minimum activity times specified within Timetable Planning Rules (TPR);
• Association lateness;
• Minimum turnaround times, where relevant;
• Timetable allowances provided within the train service schedule;
• Timetabled sectional running times;
• Any replan activity.
