After initial model preparation, the model was calibrated by comparing the DTA generated link volumes and those obtained from the Nevada Department of Transportation's (NDOT’s) Traffic Record Information Access (TRINA) database, which includes 24-hour link volumes on major roadway links collected from permanent and temporary traffic count stations. Since the Regional Transportation Commission of Washoe County (RTC) maintains the regional TransCAD travel demand model, the up-to-date network and Origin Destination (OD) demand data was obtained from RTC. DTALite was used for developing the DTA model and Network eXplorer for Traffic Analysis (NeXTA) was implemented as the user interface. The details of the DTA model development for the Reno-Sparks network were documented along with necessary model calibration. A literature review was conducted regarding DTA model development and applications. This project covered the development and calibration of a Dynamic Traffic Assignment (DTA) model and explained the procedures, constraints, and considerations for usage of this model for the Reno-Sparks area roadway network in Northern Nevada.
