Principles of Constraint-Consistent Activity-Based Transport Modeling

: This article presents “constraint–consistent activity‐based models” (CCAB), a new type of transport model that is a generalization and combination of activity‐based models and the traditional multistage transport modeling framework. Ensuring maximum consistency between the micro‐, meso‐, and macrolevels, providing compatibility to multiagent modeling techniques and using solution strategies similar to human decision‐making behavior, the new model type bridges the gap between “econometrics‐oriented” and “simulation‐oriented” research in transport modeling. The comparison of the two models in terms of their theoretical concepts, specific implementation, and data‐availability issues, as well as their potential applications gives insight into the potential of the CCAB approach in transport planning and transport policy assessment.
