Program:   Exploratory Advanced Research
Project detail
Project Description:   The project proposes research to integrate three major aspects of transportation planning: land use planning, traffic simulation and modeling, and travel demand forecasting. The innovative claims focus on the integration of these three elements across multiple spatial and temporal scales.
Goals:   The objective is to investigate approaches for multiscale model integration.
Background Information:   The project is submitted in response to a fiscal year 2007 Exploratory Advanced Research Program solicitation.

Test Methodology:   Activity-travel behavior modeling; dynamic traffic assignment modeling; land-use microsimulation modeling and computational algorithms.
Expected Benefits:   To develop a conceptual framework, an integrated prototype, and computational tools using microsimulation models.

Project Findings:   SimTRAVEL, developed in this project, is an integrated modeling system that advances land-use and transportation microsimulation by providing seamless modeling of longer term choices about location (home, work, school) and shorter term choices of activity, travel mode, and route. SimTRAVEL integrates the use of UrbanSim (a land-use model), OpenAMOS (an activity-based microsimulation model), PopGen (a state-of-the-art synthetic population generator), and DynusT/MALTA (a dynamic traffic assignment and microsimulation model) within a behaviorally robust framework. The integrated systems have been fully implemented in a user-friendly software environment with powerful graphical user interfaces and visualization dashboards. Open-source software architecture with multithreading and parallel-computing capabilities speeds simulations. SimTRAVEL was successfully tested and validated on a 500,000 population subregion of Maricopa County, AZ.
