bar) prior to be able to receive new routing information. Exceptions to this
rule: Partial routes and Parking lot routes.
Types of Routing Decisions and Routes
► Static: Routes vehicles from a start point (red) to any of the defined
destinations (green) using a static percentage for each destination.
► Partial: Defines a section of one or more static routes where vehicles
should be re-distributed according to the routes and percentages defined
by the partial routes. After leaving the partial route vehicles continue to
travel on their original route.
Partial routes also affect PT lines. In order to avoid rerouting of PT lines
restrict the Vehicle Classes accordingly.
► Parking lot (only for parking lots of type Real parking spaces): Defines a
decision point that automatically generates routes leading to each of the
selected destination parking lots and routes leading from those parking
lots back into the link network. Select parking lot(s) of the appropriate
type instead of destination point(s), cf. section 6.4.5.
► Managed lanes: Creates two parallel routes from the decision to the
destination. For a Managed Lanes Routing Decision, a user-defineable
toll pricing model and a decision model have to be selected. Thus,
vehicle occupancy (SOV, HOV2, HOV3+), simulation time and the
current traffic situation (travel time savings, average speed) are
regarded.
Relevant only for Dynamic Assignment:
► Dynamic: Defines a decision point where traffic is re-routed according to
a user-definable condition and strategy. For more information please
refer to section 12.3.1 and to section 12.7.5.
► Closure: Defines a route as a link sequence to be excluded from the set
of edges available for Dynamic Assignment. For more information please
refer to section 12.8.4.
6.4.4.1 Creating
Route definition (except routes of type Parking Lot) is a four step process. To
initialize the process, activate the Routes mode. The next required action
is shown in the status bar. To discard the recent step and return to the
previous step, left click outside the VISSIM network. Please cf. section
6.4.4.6 for details on where to place the decision and destination points.
