Volumes/Compositions Section
For each link, the vehicle inputs are arranged in columns, sorted by time
interval. For each combination of link and time interval, a data pair consisting
of a volume and a vehicle composition may be defined (empty pairs are
allowed). It is not possible to define a volume without vehicle composition or
vice versa.
It is possible to have multiple rows for the same link if there are volumes for
different vehicle compositions defined within a time interval. When sorted by
link no., these rows are identified by a combined display of the link no. and
with the same input flow name (optional).
Prior to the definition of vehicle inputs at least one vehicle composition needs
to be defined (cf. section 6.4.1).
1. Double-click on the link where the new vehicle input is to be defined. The
Vehicle Inputs window opens with the corresponding link no.
2. If a vehicle input already exists, either change it or right click and choose
NEW to create a new row for this link.
3. Define the input properties, cf. section 6.4.3.2.
