The ABM is a 4-step model that is disaggregated in three ways: spatially, temporally, and in terms of the trip chain (see Snethlage 2023b).
The spatial resolution is not defined by zones but by so-called locations. Locations represent individual buildings, building blocks, settlements, or even city districts. The resolution depends on the requirements and the data situation. Not all data need to be known at the finest resolution. Thus, different resolutions can be selected for different activities. It is also often possible to disaggregate structural data at rougher resolutions to finer resolutions using building floor plans.
The model is based on a synthetic population, i.e. persons with individual characteristics and a "schedule skeleton". Such a skeleton is a detailed schedule that lacks the data to be computed by the model: Destinations and modes as well as the resulting travel and start times.
Based on the schedule skeleton, the intertwined destination and mode choices are made, whose utility is based on temporally differentiated shortest paths between locations.
The temporal resolution usually consists of 5-8 time slices.
