Modeling vehicle routes, partial vehicle routes, and routing decisions

A route is a fixed sequence of links and connectors:

A routing decision point normally leads to several "to sections". Thereby the individual routes branch out from the routing decision point to the individual "to sections".

A route may have any length. You can use a route to simply display a turning movement at a single junction or to connect multiple nodes throughout your network. In many cases, it is useful to deploy routes throughout the Vissim network.

A routing decision only applies to vehicles that have been assigned a vehicle class and that are without any routing information. A vehicle already on a route may only accept new routing information after it has passed the "to section", i.e. destination, of its route. However, this does not include vehicles on partial routes, PT partial routes and parking lot routes.

Types of routing decisions and routes

Static routing decisions do not apply to PT vehicles (Modeling short-range public transportation), (Defining PT lines).

Partial routing decisions do not apply to PT vehicles.

Similar to when defining PT line stops, you can define PT stops for your PT partial route, including attributes for dwell time (Modeling PT lines):

As long as a vehicle has not completed its original line route, its Departure offset is treated like an offset at a stop of the original route (Attributes of PT lines). Once the PT vehicle has passed the "to section" of its original line route, the Departure offset specified for a PT partial route stop is interpreted as relative to the simulation time when the vehicle passes the respective routing decision point.

If the current Managed Lanes route is replaced with a new route at such a Managed Lanes routing decision, it is possible that the travel times for previously begun Managed Lanes routes continue to be counted until the vehicle passes its chosen destination.

The following conditions must be fulfilled for this to occur:

If the conditions are not fulfilled, the total travel time for the old route is proportionally estimated when more than 75% of the length has been completed.

Like all other routing decisions types, only the vehicles of the selected vehicle classes will be taken into account. Vehicles of a type, in which the classes are not selected here, use neither the toll route nor the toll-free route. Thus, for example, HGVs can be excluded. Note the effects of routing decisions of the type managed lanes facilities (Mode of action of routing decisions of the type Managed Lanes).
