Abstract:The Integrated Corridor Management (ICM) initiative requires the calibration and validation of simulation models
used in the Analysis, Modeling, and Simulation of Pioneer Site proposed integrated corridors. This report
summarizes the results and process for the calibration of microsimulation network for the I-15 Corridor in San Diego,
California. As one of the Pioneer Sites for the ICM project, the I-15 Corridor was simulated in TransModeler
microsimulation. Various versions of TransModeler were utilized as additional capabilities became available. The
work was conducted by Cambridge Systematics, Inc. (CS), in partnership with San Diego Association of
Governments (SANDAG). The eventual model was satisfactorily calibrated according to the guidelines set forth in
the Experimental Plan.
The report is organized into two major parts. The first part provides the final calibration results, and provides a quick
summary of the model calibration criteria and comparison against real data. The second section provides further
insights into the calibration process, including details on the software used, challenges faced, and key lessons that
can be carried forward in future projects.
