Transportation networks are a daily encounter for us all. Maintaining smooth operations is a paramount objective both for quality of service and public finances. For the...
In this project, we concern ourselves with line plan optimization on a symmetric city model. We evaluate whether and how often asymmetric solutions can occur despite the...
The Tropical Geometry of Periodic Timetables brings together the mathematical optimization of periodic timetables, a key problem in the planning of public transportation...
Optimal solutions for mobility networksThe traffic of the future consists of networked systems in which data analysis and intelligent control are an integral part. Such...
Railway transportation is one of the major transport modes for industrial goods. Nevertheless, a lack of train drivers can be observed throughout Europe, which slows down...
Algebraic and Tropical Methods for Periodic Timetabling
The mathematical optimization of periodic timetables in public transport relies on the Periodic Event Scheduling Problem (PESP), which has so far been studied almost...
Timetables dictate the daily operations of railways. Creating a railway timetable does not only involve determining arrival and departure times at stations, but also the...
Creating an optimal timetable and choosing optimal passenger routes are usually viewed as two separate tasks in traffic optimization: Timetables are built assuming fixed...
