Urbanization and Mobility

More than two-thirds of the world's population is expected to live in urban centers by the mid-21st century (United Nations, 2015).
Urbanization and suburbanization lead to an increase in commuter movements, resulting in a higher load on the transport infrastructure, especially during peak hours.
Developing sustainable mobility concepts is crucial for resource and climate protection.

Public Transportation

Efficient local public transportation plays a central role in sustainable mobility.
Public transport systems need to be built or upgraded to meet the increasing demand for transport.

Transport Capacity

Transport capacity is determined by the product of the number of trips per hour and the vehicle capacity (number of available seats and standing spaces).
The performance of a line depends on factors such as existing infrastructure, rolling stock characteristics, and railway operations planning.

Increasing Performance

Optimization of vehicle characteristics can increase performance, including:
- Improved driving dynamics
- Higher acceleration and braking capacity
- Increased distance between station stops at maximum permissible speed
- Faster passenger exchange at stops through design of doors and platforms
Holistic approach to system design is required, as illustrated in the Ishikawa diagram.
