A journey by public transport is often a complex combination including multiple modes of transport. At the same time, travelers may have different needs and preferences.
For a transit agency it is useful but also very difficult to describe the total travel flows of passengers; where and how do they transfer between lines and modes of transport.
When a transit agency is able to describe passenger flows, this can serve as a foundation for adapting and optimizing the network in order to meet the actual transport needs of passengers.
With data from multiple sources like passenger counts and travel cards, it is now possible to perform a wide range of analyses and to forecast how and to what extent passengers’ journeys will be affected by changes in timetables and lines.
