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.
