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

Large-scale Traffic Simulation Models
Metropolitan to regional scaleHigher realism/fidelity operational modelsDesire to inform demand models with traffic simulation
Data produced is on a different scale:San Francisco ~ 700,000 veh demandSeattle ~ 460,000 vehicles veh demand

We need Methods to explore this dataAnd tools to work with them efficiently
