What is TERI?

The Transportation and Environmental Research Ideas (TERI) database is a central storehouse for tracking and sharing new transportation and environmental research ideas. The Center for Environmental Excellence by AASHTO maintains TERI and keeps all content current. Suggestions for new ideas are welcome from practitioners across the transportation and environmental community.

Examples of Recent Proposals

• Context-Sensitive Design Options for Workhorse Bridges in Rural Historic Districts
