6 The Traffic Network
Managed
Lanes
During the simulation start, VISSIM checks for partial routes and managed
lane routes whether all destination cross sections starting from the same
start cross section have the identical position on the identical destination
link. If not so, the destination link number and the position (at [m]) of the
route having the smallest route number will be used for any other partial
route or managed lane route starting from this decision cross section.
During a simulation, routing decisions of the managed lanes type do only
control the route choice of those vehicles which are already either on a
static route or on one of the two routes starting from a routing decision of
the managed lanes type. Vehicles on dynamic assignment paths are not
regarded by those routing decisions.
The managed part of a highway we call a separate road built in parallel to
the normal - unmanaged part of the - highway. Normally, the managed part
of the highway is equipped with numerous feeders for access and egress of
vehicles. Routing decisions of the managed lanes type serve for modeling
the so-called “part-distance“ use of managed and unmanaged sections of
those roads built in parallel.
