Normative optimal strategies: A new approach in advanced transit trip planning

The paper focuses on unreliable dynamic transit service networks, on which trip planners should give strategy-based path suggestions, rather than a set of single paths from origin up to destination. Different types of optimal strategies, with their related hyperpaths and diversion rules, are defined and analyzed. A search method of a normative optimal strategy, which considers short and long term path attribute predictions, is presented and applied to a test network.
