Building an Abstract Network Graph
The dynamic assignment creates an abstract network graph as a basis for the calculation. An abstract network graph links the network objects relevant for the dynamic assignment. This includes the parking lots, from which the vehicles enter the network, or which are the destination of the vehicles, as well as nodes and edges. When you start dynamic assignment, Vissim generates an abstract network graph based on these network objects. When you perform dynamic assignment with mesoscopic simulation, Vissim additionally generates a meso-specific network graph (Mesoscopic node-edge model).
