Abstract:This technical report documents the calibration and validation of the baseline (2008) mesoscopic model for the I-394
Minneapolis, Minnesota, Pioneer Site. DynusT was selected as the mesoscopic model for analyzing operating conditions
in the I-394 corridor study area, and the report provides details on the network development, traffic flow model calibration,
origin-destination (OD) demand calibration, and model validation. In addition, the report provides a modeling methodology
for simulation of transit, as well as the results of a sensitivity analysis, utilizing information from a known incident,
undertaken to verify the ability of the validated model to replicate operating conditions for incident scenarios.
In summary, the DynusT model for the I-394 corridor replicated the 2008 baseline operating conditions well as evidenced
by the comparisons of observed and modeled volumes, travel times, and speed contours on I-394. Furthermore, the
simulated known incident exhibited consistent traffic diversions, speed reductions, duration, and queue propagation with
the actual data.
