Résumé
Transit path calculation is not yet widely available on transit authority websites, because the calculation of complete transit itineraries requires the integration of underlying components like geographic information systems and operational databases, and, unlike a simple road application, involves a complex transportation network. In this paper, a hybrid algorithm based on heuristics and optimization is presented for the calculation of urban transit itineraries which covers information on pedestrian access and egress paths, route sequences, schedules and stops. The use of the Transit User Information System (TUIS) to support the calculations is emphasized. The TUIS uses the Totally Disaggregate Approach and Object-Oriented Modeling in transportation to gather data on territory (for origin and destination specifications and for the pedestrian network) and transit operation (route geometry, schedules). Websites which have been implemented are referenced to demonstrate the applicability of the hybrid algorithm. These websites make use of some special techniques for disseminating user information over the Internet. |
