This volume gives an overview on new theoretical approaches on computer-aided methods for strategic and operational planning in public transport. The papers of this volume cover the most important steps of the complete process of planning and operational control in public transport and public mass transit. Readers of this book obtain detailed information on current developments in vehicle and crew scheduling and in solving such problems in practice. Interesting results in scheduling theory are shown, using procedures for solving combinatorial problems with more complex structures. Furthermore, experiences in the application of specific software tools are presented.

This proceedings volume consists of papers presented at the Sixth International Workshop on Computer-Aided Scheduling of Public Transpon, which was held at the Fund lio Calouste Gulbenkian in Lisbon from July 6th to 9th, 1993. In the tradition of alternating Workshops between North America and Europe - Chicago (1975), Leeds (1980), Montreal (1983), Hamburg (1987) and again Montreal (1990), the European city of Lisbon was selected as the venue for the Workshop in 1993. As in earlier Workshops, the central theme dealt with vehicle and duty scheduling problems and the employment of operations-research-based software systems for operational planning in public transport. However, as was initiated in Hamburg in 1987, the scope of this Workshop was broadened to include topics in related fields. This fundamental alteration was an inevitable consequence of the growing demand over the last decade for solutions to the complete planning process in public transport through integrated systems. Therefore, the program of this workshop included sections which dealt with scheduling problems and computerized systems for operational planning as well as sections on network planning and data management.

This volume consists of papers presented at the Fourth International Workshop on Computer-Aided Scheduling of Public Transport, which was held in Hamburg from 28th to 31st July 1987. The first of this series of Workshops was held in Chicago in 1975. Papers presented then tended to look forward to what might be done in the future application of computers to problems in transit scheduling. No presentations described systems which had been implemented and were being used on a regular basis, although a few papers discussed apparently successful once-off applications in both bus scheduling and bus crew scheduling (or run-cutting). However, within a few months of the end of that first workshop some systems had been implemented, both in Europe and in North America. By the time of the second Workshop, in Leeds in 1980, several systems were in regular use. Most of the crew scheduling implementations were based on heuristic methods (e.g., RUCUS), although mathematically based methods were being used in Quebec City and in Hamburg, and several papers described further mathematical methods in the course of development. A wide variety of bus scheduling approaches was reported, many of them being in regular use.

Sollen Mobilitat und Lebensraum im Europa des 21. Jahrhunderts erhalten bleiben, so sind Konzepte gefordert, die einen Beitrag zur wirtschaftlichen und oekologisch vertretbaren Mobilitatsbewaltigung leisten. Das Buch bietet hierzu einen umfassenden Einstieg in das Informationsmanagement im Verkehr. Ausgehend von UEberlegungen zu einem Ebenenmodell des Informationsmanagements lassen sich aus betriebswirtschaftlichen und entscheidungsorientierten Anforderungen Unterstutzungsleistungen ableiten, die unter Verwendung geeigneter Informations- und Kommunikationstechnologien zu erbringen sind. Im Vordergrund der Betrachtungen stehen die zu fordernden Funktionalitaten an entsprechende Applikationen und die hierfur benoetigte Infrastruktur. Anhand von Beispielen aus der Praxis werden Anwendungen aus den Bereichen oeffentlicher Personenverkehr, motorisierter Individualverkehr und Guterverkehr vorgestellt.
