Dynamic Traffic Assignment Modeling of Valencia Corridor

​

In this study, the Pima County Department of Transportation (PCDOT) team sought technical
support from the University of Arizona (UA) Center for Applied Transportation Sciences
(CATS) team to conduct a mesoscopic Dynamic Traffic Assignment (DTA) modeling of a study
area (west of I-19 and south of Ajo Hwy), with a specific focus on the Valencia corridor in the
Pima County region. The study used Dynamic Urban Systems for Transportation (DynusT), a popular commercial DTA software. Specific tasks in the study involved data collection, updating a base model (previously developed for the Pima County region), simulation of the base model, the measures of effectiveness (MOE) analysis of the base model, scenarios identification, MOE
analysis of scenarios, and drawing comparisons across the base and scenario models.
