This report will be of interest to professionals who use travel demand and network assignment models as part of the transportation planning process. The goal of this research was to improve urban-scale modeling and network procedures to address operations or spot improvements that affect travel time choice, route choice, mode choice, reliability, or emissions. Such improvements may include traveler information, pricing, reversible lanes, and improved bottlenecks. Operational improvements like these are difficult to model on an urban-area scale using existing tools. A secondary goal was to facilitate further development and deployment of these or similar procedures. The goals were addressed by building a proof-of-concept dynamic integrated model in two urban areas: Jacksonville, Florida, and Sacramento, California. The integration of the activity-based demand model DaySim and a Dynamic Traffic Assignment (DTA) model, TRANSIMS, in Jacksonville, Florida, is the subject of this report. Both DaySim and TRANSIMS are open-source products. Integration means that a feedback loop was built between the demand and network assignment model systems. All the demographic and network data required to run the model set were assembled, and the feedback between the demand model and the DTA was tested in Jacksonville, Florida, and Burlington, Vermont. The model set is structured so that it can be run in a long-range planning mode, a short-term operations mode, or a combined mode. A companion report and model set are available for the application in Sacramento, California. This work has the same objective but uses DynusT for the highway network assignment and adds a schedule-based transit assignment called FAST-TrIPs. DaySim was also used as the demand model. Both model sets and software start-up guides are available from the Federal Highway Administration.
