TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 246: Volume 2: TRAQS: A Combined Interface for Project-Level Air Quality Analysis documents the development of TRAQS (TRansportation Air Quality System), a Graphical User Interface-based software application that simplifies project-level air quality analysis of mobile source emissions. TRAQS integrates the “modeling chain” components of traffic activity, mobile emissions, and air dispersion modeling.
TRAQS is designed to streamline the model process and minimize any limitations of standalone software packages by integrating individual models and databases into a user-friendly, intuitive Graphical User Interface. It provides access to advanced modeling tools and mapping features. Overall, TRAQS offers the capabilities necessary to complete a Project-Level air quality analysis with increased accuracy and efficiencies.
