Type
ID – a discrete service (like an express service, stopping service
or train belonging to a particular line)
D(istribution)
– the percentage distribution used to divide demand into suborigins (could for
example be carriages in a train)
Suborigins –
Entrances generated by subdividing the initial Arrival Profile (for example,
each car in a train will be imported into
LEGION Model Builder as an Entrance)
Frequency
based? – answer ‘Yes’ to this if you want to subdivide the initial
Arrival Profile into pulses according to frequency)
Service type
sequence – the pattern of train services (for example, ‘Express –
Express – Stopping – Express’)
Continuous or
Per Interval – a ‘continuous’ sequence repeats itself across the
runtime of a simulation and across time intervals (without restarting), whereas
a ‘per interval’ sequence respects the start of each new time interval and will
restart the sequence at the beginning of each one.
Arrival
frequency – the number of times a service arrives (throughout the
whole runtime or within specific intervals)
All
– this denotes that a value applies for all time intervals or affects all Type
IDs or Availability Profiles.
