New Generation Travel ModelsTravel models are increasingly
disaggregate30 Activity Based Models (ABM) underway in North
AmericaTour-based models in AustraliaGenerally increasing market
segmentation, temporal and spatial resolution
Data produced is on a different scale:Seattle ABM ~ 3 million
people, 14 million activities, 1.6 million parcelsPhoenix ABM ~ 4
million people, 20 million activities, 26000 MAZs

A Lot of Model Data Still Goes UnseenMeaningful data from
models, but very disaggregate
