Optimally combined headway and timetable reliable public transport system

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...

Why Does Public Transport Not Arrive on Time? The Pervasiveness of Equal Headway Instability

BACKGROUND The equal headway instability phenomenon is pervasive in public transport systems. This instability is characterized by an aggregation of vehicles that causes inefficient service. While equal headway instability is common, it has not been studied independently of a particular scenario. However, the phenomenon is apparent in many transport systems and can be modeled and rectified in a...

Automatic Timetable Generation System

This paper discusses the various approaches that can be taken to solve the timetable generation problem. Timetable generation is basically a constraint satisfaction problem. The methods discussed in this paper are capable of handling both soft and hard constraints. Once the final timetable has been generated, teachers and students can access it through three different views i.e., class view, la...

Is Timetabling Routing Always Reliable for Public Transport?

Current route planning algorithms for public transport networks are mostly based on timetable information only, i.e., they compute shortest routes under the assumption that all transit vehicles (e.g., buses, subway trains) will incur in no delays throughout their trips. Unfortunately, unavoidable and unexpected delays often prevent transit vehicles to respect their originally planned schedule. ...
