In the next section, a summary and critique of the convention trip-based approach is presented, followed by an overview of activity-based approaches, focusing on how these approaches address the various limitations of the conventional model. This is followed by a  review of representative examples of activity-based approaches, including several perhaps best considered as contributions to understanding travel behavior, and several oriented toward direct application in forecasting and policy analysis. Some summary comments are then provided including an assessment of the future of both trip-based and activity-based approaches.
