Improving Public Transport Timetable Coordination in Melbourne

There is a growing need to maximise the utility of multimodal public transportation by designing timetables that are as coordinated and reliable as possible. But with multiple trains, trams and buses operating at any given time in Melbourne, the logistics are complex.

This research focuses on developing a holistic optimisation tool that improves the efficiency of public transport timetables. It aims to model timetable coordination as a constraint based optimisation problem, incorporating a comprehensive set of real world constraints that address the practical concerns of public transport users and schedulers alike. It broadly explores the following:

  • What are the limitations with existing approaches in efficiently coordinating timetables?
  • Can a holistic, adaptive algorithm be developed to deliver improved scheduling opportunities than the existing tools for local and network level operations?
  • How well can we optimise timetable coordination and cost efficiency simultaneously and make transfers more convenient and reliable?
  • What are the impacts of improved coordination on public transport ridership?

The outcome from this research intends to aid transit agencies with faster decision making-to realise accurate, realistic and cost-efficient timetable solutions. It ultimately seeks to achieve a synergy between scheduling in principle and scheduling in practice.

This project is part of the Sustainable and Effective Public Transport – Graduate Research Industry Partnership (SEPT-GRIP) and is supervised by Professor Mark Wallace and Professor Graham Currie with industry supervision from Chris Loader. The project is being undertaken by Rejitha Nath sponsored by Transport for Victoria and Monash University.
