Placing a routing decision of the Managed lanes type
When defnining a routing decision of the managed lanes type, follow the
outlined steps. Place
► on the unmanaged part of the highway: a decision before each feeder
from the unmanaged to the managed part of the highway which are in
parallel. For each of these decisions, place the destination behind the
nearest possible exit from the managed part towards the unmanaged
part.
► on the managed part of the highway: a decision before each feeder
from the managed part of the highway to the unmanaged part of the
highway. The destinations for each of these decisions place behind the
nearest possible exit from the managed to the unmanaged part on the
unmanaged part of the highway.
When passing a routing decision of the type Managed lanes for the first
time, a vehicle receives a random number indicating the probability for
changing to the managed lane. The vehicle will use this random number for
any other routing decision of the type Managed lanes. This way it can be
guaranteed, that only in case of heavily changing traffic conditions the
vehicle might change its initial decision.
Two routing decisions of the managed lanes type should use the same
Managed Lane Facility only if the following applies:
► The courses of the unmanaged routes starting from these decisions are
closed to identical.
► The courses of the managed routes starting from these decisions are
closed to identical, too.
Graphical display of a routing decision of the Managed lanes type
Via menu VIEW - NETWORK ELEMENTS open the Display of Network Elements
window and
► check option Routing decision and
► select Managed Lanes Data in the Label column.
Then, the network display on screen will show
► the number of the decision of the Managed lanes type,

► the current road toll charged for user group 1 Person (SOV).
Evaluations regarding routing decisions of the Managed lanes type
Via menu EVALUATION - FILES you can check the Managed Lanes option to
