VISSIM 5.30-05 User Manual

The subroute to be closed is defined in
the same way as a static route is
defined, i.e. they have a starting point
and a destination point.
Route closures can be created and
edited using the Routing Decisions mode
by selecting Closure in the Create
routing decision window. For more
information on Routing Decisions please
refer to section 6.4.4.
12.8.5 Generation of Static Routing
Assignment Control
VISSIM offers the possibility to convert the current state of the Dynamic
Assignment (the routes found and their volumes) into a VISSIM model with
static routes. It is then possible to use the simulation without the Dynamic
Assignment module; in other words: the assignment is frozen.
Vehicle inputs and routing decisions are created from the current data of the
Dynamic Assignment files (*.WEG, *.BEW, *.FMA).
Make sure, that the simulation period is a multiple of the evaluation interval
for Dynamic assignment, since path file and cost file save the data by
interval and would otherwise be incomplete.
Vehicle inputs and routing decisions are directly generated from the route
volumes being stored in the path file:
► At least one vehicle input per time interval is created for each origin
parking lot (parking lot with relative flow > 0). Its volume is summed up
from all volumes of paths listed in the *.WEG file which start from this
parking lot.
► One static routing decision is created for each origin parking lot per
vehicle type group which is a set of vehicle types with identical route
choice behavior in the Dynamic assignment (identical cost coefficients,
identical connector closures, identical destination parking lot selection
parameters etc.). The relative flow of each route to a destination parking
lot equals the path volume listed in the path file.
- The identifier of any vehicle input automatically created is 1,000
times the parking lot number plus the index of the time interval.
