Population synthesis for microsimulating travel behavior.
As of 2014, in the US, activity-based modeling is still in its formative stages and not yet standard practice. Explaining activity-based models to a general audience is an ongoing exercise. The specification of these models largely emerged from shift in policy challenges put before transportation planners; specifically the need to evaluate highway pricing and other demand management strategies as well as the impacts of land use planning that seek to mitigate travel demand, such as transit-oriented or neo-tradtional developments. The modeling features most common to the activity based modeling architectures currently include: population synthesis, daily activity pattern formulation, tour formation and time-of-day and mode choice. Activity-based models fall into the category of tour-based models. Also common among current activity based models is the attention paid to maintaining a high degree of specification along both the person and geographic dimensions. This has been made possible by rapid advances in both GIS and computational capacity that permit processing and storage of much finer geographic specification (e.g. parcels) and microsimulation and tracking of individual travel choices. These features permit the model results to retain the disaggregate character of the original [Travel survey data|travel survey] data; making them appealing to a wide variety of policy analyses.
