Path sequences describe sequences of zones or paths between zones with a volume. Each path starts in the zone in which the previous path ended. The course of the paths in the network are not necessarily known. Path sequences allow you to illustrate the overall connection of a path. In contrast to PrT or PuT-paths, path sequences with identical origin and destination zones can be useful and are, e.g., generated as a result of demand calculation (e.g. trips or daily signal program lists).
Path sequences and their items are not editable and can only be created as follows:
- as a result of a multimodal assignment
- as a result of the procedure P+R lot choice
- as a result of the procedure "Tour-based model - Combined trip distribution / mode choice"
- by importing path sequences from external data sources
Path sequences belong to a path sequence set. These usually describe the origin of associated path sequences, for example by means of a reference to a demand segment or a demand stratum. The course of a path sequence is defined by path sequence items. A path sequence must include at least two items. Path sequences-items describe both a location (zone) and the path to the next item.
The network object path sequence activity is an activity in the zone of the path sequence item. If the path sequence comes from a demand model, e.g. trips created in a tour-based model, path sequence activities also include activities in the sense of the demand model. However, most activities are more general in nature and may exist without a demand model. This is where they differ from the network object "activity".
