The second presentation will begin with an overview and description of the technical underpinnings of each of the individual components that comprise this new paradigm in transport modelling. It will then discuss recent advances using project examples such as San Diego where all location choices are based upon a fine level of spatial resolution that allows for improvements in understanding access and egress to public transport, better representation of non-motorised travel, and incorporation of explanatory variables that respond to transit-oriented development strategies and related plans. Other notable advancements in Activity-Based models have been the modelling of travel time reliability as a function of perceived highway time and congestion levels, and the inclusion of parking choice and constrained parking equilibrium models in congested Central Business Districts. The presentation will also describe the basic structure, implementation, and application of these new advancements.

The presentations will conclude with a discussion of the level-of-effort associated with moving to Activity-Based Models and the opportunities for creating transition strategies from a trip-based to an activity-based framework.
