FHWA Effective Integration of Analysis, Modeling, and Simulation Tools

KAI led a team to define a model integration concept of operations and requirements that enabled the efficient information exchange and data transferability among models of various domains and scale. These new methods and tools were validated through two demonstrations using the NeXTA open-source data hub and data schema, developed as part of the project. Data can be visualized using Google Fusion Tables® to store transportation model input and output data from travel demand forecasting models, mesoscopic dynamic traffic assignment models, and microsimulation models. The team also prepared a state-of-the-practice report that summarizes integrated modeling activities within and outside of the transportation sector.
