12 Dynamic Assignment Example: If we describe to our neighbor the way from its home to a restaurant, we tell him a series of intersections, and whether he must turn left or right there, but no more details. In VISSIM an abstract network representation is built for Dynamic Assignment and the user defines the parts of the network model that are to be considered as nodes. Normally the user will define as nodes what corresponds to the real-world intersections. The process of building the abstract network and working with it is described in section 12.3. The iteration of the simulation runs is continued until a stable situation is reached. Stable here means that the volumes and travel times on the edges of the network do not change significantly from one iteration to the next. In VISSIM this situation is called convergence and the criteria for convergence can be defined by the user. The following flow chart illustrates the principle of the Dynamic Assignment as explained above. 594 VISSIM 5.30-05 © PTV AG 2011
Principle of Dynamic Assignment Input Route Search Route Choice Simulation & Travel Times Query • Load trip matrix for all OD • Build node-edge-graph • Convergence criterion • Max number of iterations N n = 0 For all edges: set expected travel time = distance n = n + 1 For all OD: Search route with minimum cost Add new route to the set of routes For all OD: Split demand onto all routes For all OD and all vehicles (simultaneously): Perform microscopic simulation For all edges: Calculate travel time and cost n >= N OR Convergence criterion fulfilled YES End of assignment Principle User Manual © PTV AG 2011 595 NO
