Environment Group

TTI’s Environment Research Group conducts sponsored research related to transportation and the environment, including in our state-of-the-art laboratory facilities and the field.

Environment Divisions


Air Quality and Environment

The Air Quality and Environment Division are experts in transportation energy and its impacts on human and environmental health. The team addresses transportation air quality in the broader context of sustainability, health equity, climate change, transportation electrification and decarbonization.

Center for Healthy and Efficient Mobility

The Center for Healthy and Efficient Mobility (CHEM) focuses on transportation and public health. The consortium is led by the TTI and consists of six partner universities: Johns Hopkins University, Georgia Institute of Technology, University of Texas at El Paso, University of California, Riverside, Morehouse School of Medicine and North Dakota State University. CHEM is funded by a grant under the Infrastructure Investment and Jobs Act for a Tier-1 University Transportation Center.

Environmental Testing Facilities

TTI’s environmental testing facilities support cutting-edge research in erosion control, stormwater management, clean transportation and electric grid interactions. Located at the Texas A&M-RELLIS Campus, these one-of-a-kind labs help advance safer, more sustainable infrastructure.
