TEXASTWG.ORG

This website provides transportation practitioners in Texas with a single, centralized resource that provides information about current and emerging transportation air quality issues, including transportation conformity. This portal was developed by the Texas A&M Transportation Institute (TTI), for the Texas Department of Transportation (TxDOT) as part of the Air Quality and Conformity Technical Support and Analysis interagency contract. The Texas' Technical Working Group (TWG) for Mobile Source Emissions also operates under this contract, and the portal contains reports, information and resources compiled by TTI under this contract over the past several years.
