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...

Passenger routing for periodic timetable optimization

The task of periodic timetabling is to schedule the trips in a public transport system by determining arrival and departure times at every station such that travel and transfer times are minimized. To date, the optimization literature generally assumes that passengers do not respond to changes in the timetable, i.e., the passenger routes are fixed. This is unrealistic and ignores potentially va...

Performance of Algorithms for Periodic Timetable Optimization

During the last 15 years, there have been proposed many solution methods for the important task of constructing periodic timetables for public transportation companies. We first point out the importance of an objective function, where we observe that in particular a linear objective function turns out to be a good compromise between essential practical requirements and computational tractabilit...

A Fuzzy Optimization Model for High-Speed Railway Timetable Rescheduling

A fuzzy optimization model based on improved symmetric tolerance approach is introduced, which allows for rescheduling high-speed railway timetable under unexpected interferences. The model nests different parameters of the soft constraints with uncertainty margin to describe their importance to the optimization purpose and treats the objective in the same manner. Thus a new optimal instrument ...
