[DYNAMIC
ASSIGNMENT]
● Zone:
Allocated zone
no. from OD
matrix. To a
zone, several
parking lots
can be
allocated.
● Group (only for
Real parking
spaces):
Freely selectable
number
for parking lot
grouping. Without
a number =
the parking lot
does not
belong to a
group.
● Capacity (only for Abstract parking lots): cf. above.
For Real parking spaces the value results from the parking lot Length
and the Length of each space, the displayed capacity is not subject to
changes.
● Initial occupancy (only for Abstract parking lots and Real parking
spaces): The value indicates the parking lot occupancy at simulation start
which is regarded for destination parking lot choice (also for dynamic
routing decisions) calculation. Furthermore, it is used to determine if a
parking lot is full. The initial occupancy should not include vehicles that
arrive at the parking lot within the simulation period and might leave from
there later (could be contained in matrices). For Real parking spaces, the
composition of the initial occupancy is listed.
● Composition (only for Real parking spaces): For the initial occupancy,
select the appropriate vehicle composition, cf. section 6.4.1.
● Rel. flow: Only relevant, if a zone has multiple parking lots: Percentage of
the zone´s total demand, e.g. value 0 = no demand, (e.g. if a parking lot
is located on a link having no successor). The values of several parking
lots per zone are summed up and the total is set = 100%, then the appropriate
share per parking lot is caluclated.
● Desired Speeds: Desired speed distributions allocated to vehicle classes.
Default: just a single vDes-distribution for all classes.
● Label: When showing labels of all parking lots (see VIEW - NETWORK
ELEMENTS...) this option allows to individually switch off the label of that
one. Options for parking lot labels: Number, Name, Zone no., Group no.,
Occupancy and Parking Availability.
