Tiivistelmä
This report summarises findings from a comparison of aggregate and disaggregate approaches to transport modelling. The comparison was based on a literature review that examined different approaches to transport modelling. In the literature review, 920 unique papers were screened, 56 were included in the study, and categorised in this report.
Aggregated and disaggregated approaches to transport modelling are compared based on characteristics such as considered modes of transport, demographics, used data types, and reported limitations. We found that the available data and goals of the model should guide the chosen approach of the model. Questions about the needed level of detail in the data and population composition should be actively discussed during the planning or development process of a transport model.
Limitations of the report include methodological choice of single screening and a division process that required some interpretation. This report is funded by the Business Finland’s Decarbonizing transport and Mobility through data-driven modal shift (DeMo)-project.
