Environment and Air Quality Division

The Environment and Air Qualities Division of TTI consists of three programs: The Air Quality Program , Environment Management, and Transportation Modeling. The researchers at the Air Quality Program focus on transportation-related air quality and allied considerations, covering a range of topics such as mobile source emissions (including greenhouse gases), transportation sustainability, energy and climate change. Research in the Environmental Management Program involves identifying, analyzing, and developing solutions for sustainable roadsides. The Transportation Modeling group gives sponsors the information they need to achieve compliance with federal clean air standards.

Mobility Division

The Mobility Division of TTI consists of three programs: Mobility Analysis, Transit Mobility, and Urban Analysis. The Mobility Analysis Program researches a range of mobility issues, from measuring the problems to estimating the benefits and evaluating solutions. The Transit Mobility Program provides research and technology transfer expertise in all aspects of public transportation planning, management and operations. The Urban Analysis Program staff’s technical specialty is transportation planning. Researchers lead and assist in a wide spectrum of transportation planning technical activities.

Planning Division

The Planning Division of TTI consists of three programs: Mobility Management Program, Transportation Planning and Travel Forecasting. The Mobility Management Program provides TTI with a physical presence in the capital city—an office close to our largest sponsor, the Texas Department of Transportation (TxDOT), and the Texas Legislature. Researchers in the Transportation Planning Program study travel behavior and travel data collection methods. The overall goal of the Travel Forecasting Program is to support and assist public agencies in the implementation and application of current and emerging technologies in travel forecasting.
