Institut für Planung des öffentlichen Verkehrs | Institute of Public Transport Planning (IPTP)

Welcome to the Institute of Public Transport Planning!

Providing mobility to all, regardless of socio-economic status and physical condition, is the social role and overarching aim of public transport. At the Institute of Public Transport Planning (IPTP), launched in September 2025 at Technische Universität Braunschweig, we specialise in all fields of public transport design at the operational, tactical and strategic planning levels. Sustainability and social equity issues are considered together with the economic and financial side of public transport systems. Our topics of research include:

  • Service design, including optimisation of networks and service levels.
  • Environmental externalities, decarbonisation and life-cycle assessment.
  • Health benefits of walking and cycling as complementary modes to public transport.
  • Public transport pricing optimisation and social effects.
  • Public transport demand estimation.
  • Impacts of extreme weather on public transport systems.
  • Quality of service, including the effects of reliability and passenger crowding.
  • New technologies: the effects of vehicle automation on the future of public transport.
  • Shared modes (e.g., bike-sharing, car-sharing) and their relationship to public transport.
  • Ride-pooling and flexible forms of public transport.

Since September 1st 2025, the head of the Institute of Transport, Railway Construction and Operation (IVE) will be our new Professor Dr Alejandro Tirachini, setting a new research focus as the Institute of Public Transport Planning (IPTP). Prof Dr Tirachini was previously Visiting Professor and Humboldt Fellow at the Technical University of Munich (2019-2020) and Associate Professor at the University of Twente (2023-2025). He is also a part-time professor at the Universidad de Chile.

His main research interests are the design, planning and operation of public transport systems and the study of shared mobility and emerging mobility technologies from a sustainable mobility perspective. He has worked on transport research projects in Chile, Australia, Germany, the Netherlands, Singapore and Mexico. He has been co-editor of the Journal of Public Transportation (2019-2024) and co-editor of the Handbook on Transport Pricing and Financing (Edward Elgar Publishing, 2023).
