Activity-Based Travel Forecasting Models in the United States: Progress since 1995 and Prospects for the Future

Abstract

This paper focuses on the use of activity based models in practice for urban and regional planning in the United States (U.S.). In addition to projects that have been carried out, also recognized is work done in a variety of research settings, both inside and outside the U.S. that will assist in the choice of activity based models in the future. Regional planning in the U.S. is at a critical stage with the adoption of activity based models accelerating. The paper's goal is to provide an opportunity to review the types of modeling developments that have been successfully implemented. Also discussed are factors that remain as hindrances to the acceptance of activity based models for planning by U.S. government agencies.
