Title: Integration of Activity Scheduling and Traffic Assignment in ADAPTS Activity-Based Model
Accession Number: 01373811
Record Type: Component
Abstract: While travel demand and traffic assignment models become more and more mature, and while each model is highly dependent on the other one, a fully dynamic integrated model has not been implemented yet. The work that is presented in this paper is an effort toward advancing the state of integration between activity-based models and traffic assignment routines. In this study, a time-incremental dynamic traffic assignment model has been developed and integrated with ADAPTS, a dynamic activity based travel demand model developed for the Chicago region. Despite other integration studies, the most updated level of service (LOS) from the dynamic traffic assignment (DTA) model is used in updating activity plans and schedules during the simulation. For validation, a 10% sample of the population of the region were synthesized and fed into the integrated model. The model then generated travel activities of individuals and simulated them on the network while updating activity plans and schedules at the end of each interval using updated network condition.
