Moving Ahead for Progress in the 21st Century (MAP-21) authorized funding for a new FHWA research program that strengthens transportation planning and environmental decisionmaking. The program's key components will be projects and programs that:

  • Minimize the cost of transportation planning and environmental decisionmaking processes, highway infrastructure, and operations.
  • Improve transportation planning and environmental decisionmaking coordination and processes.
  • Minimize and reduce the potential impact of highway infrastructure, operations, and surface transportation on the environment.
  • Improve construction techniques and reducing congestion and related emissions.
  • Reduce the impact of highway runoff on the environment.
  • Improve the understanding and modeling of factors that contribute to the demand for transportation.

The details of the program are being finalized. Please visit to find the latest information about this program and FHWA's research efforts.
