MATSim

So that if they really want to understand the customer, they need to understand the full chain of trips and actually the full activities.

So in the context of the Swiss Railways, they have developed themselves their own activity-based model based on the data, and they are using it with a traffic simulation called MatSim.

So they are really using the full chain of models.

The reason is that because they need to forecast to plan the infrastructure, they need to forecast for a long period, and they need to understand exactly why people will take the public transportation and the trains.
