Periodic Timetable Optimization in Public Transport

To my family—in particular to Annika and to our three children. .. Preface Well, " is this really a math book " ? This is the question the reader might have in mind until Proposition 4.2 on Page 31. Indeed, the first chapters—as well as the very last one—address a very general readership, including scientists and practitioners in traffic engineering and economics. This is because to me, periodi...

Solving Periodic Timetable Optimisation Problems by Modulo Simplex Calculations

Abstract. In the last 15 years periodic timetable problems have found much interest in the combinatorial optimization community. We will focus on the optimisation task to minimise a weighted sum of undesirable slack times. This problem can be formulated as a mixed integer linear problem, which for real world instances is hard to solve. This is mainly caused by the integer variables, the so-call...

Automating the Import of Electronic Timetable Data to EMME/2-Based Public Transport Models

One of the speakers at RailDelft2005 issued a “plea for standardised models” for the simulation of railway operations. This issue is highly relevant in Britain, where the industry-standard CIF (Common Interface Format) timetable data files are not directly compatible with modelling tools such as RailSys and EMME/2. RMCon has developed a CIF import facility for RailSys, but no equivalent exists ...

Public Transport Ontology for Passenger Information Retrieval

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...
