The “Data Hub” was created to simplify complex transportation analyses requiring more than a single resolution (macro, meso, micro, deterministic), for applications such as Integrated Corridor Management (ICM), roadway pricing/tolling, and air quality analysis.
The Data Hub uses a data schema to manage the interchange of data from common off-the-shelf software programs. The graphical user interface displays measures of effectiveness from field and model data in a side-by-side format which enables more effective calibration and validation processes.
A prototype Data Hub was successfully tested on subarea networks in Portland, OR; Tucson, AZ; and Raleigh, NC. Additional applications are currently being undertaken by the research team to demonstrate its benefits.
