A person-centered multi-modal all-day dynamic transport model prototype of the Greater Stockholm region is developed, with the main objective of providing a system perspective of how waterborne urban mobility interacts with and contributes to urban transportation in its entirety.

The model prototype is implemented using the MATSim simulation technology and integrates a sketch version of the national travel demand model Sampers, an extract from the national road database, and the complete public transport schedule of the Greater Stockholm study region. The model system represents all-day travel chains per synthetic traveler and hence allows studying how different population segments make (often combined) use of available transportation facilities.

Even though only coarsely calibrated, the model system generates plausible modal shares and within day travel dynamics. A detailed study of a fictitious new boat line demonstrates the analysis possibilities provided by the model system. Both a base case (without the new line) and a policy case (with the new line) are simulated, using the same synthetic population. This allows identifying all synthetic travelers switching to the new boat line, as well as analyzing how the new line is integrated into their all-day travel patterns.

The model prototype is set up without dedicated data collection, demonstrating that detailed simulation can reveal detailed structure without an excessive data collection burden. Clearly, the present model prototype is not yet ready for use in daily planning practice. It is, however, demonstrated that the development of a person-centric all-day dynamic transport model is not necessarily by orders of magnitude more complicated than setting up a traditional, much less detailed, continuum flow model.
