Nodes determine the locations of street junctions and points in the railway network. They are starting and terminating elements of links, where there are turning relations from one link to another in PrT or PuT transport systems (Turns). Optionally, a major flow can be defined for every node specifying the direction of the flow with the right of way. The major flow which has the right of way can be determined automatically by Visum from the ranks of the intersecting links (Links). Any number of nodes can be incorporated in a main node (Main nodes). Impedances can be modeled for nodes, which then have an effect on the route search and thus on the assignment results (Impedances at nodes). This is how influential factors on time can be integrated in the assignments, which a vehicle needs to cross an intersection.
