Enhancing Transportation: Connecting TSMO and Environment
U.S. Department of Transportation
TSMO can support environmental goals by reducing congestion, supporting multimodal solutions, and advancing strategies that increase mobility without the need to expand roads or undertake major construction. TSMO strategies support a multimodal approach to transportation, and focus on the movement of people and goods, and not solely on vehicles.
TSMO can benefit the environment by:
TSMO and environmental professionals all benefit when they collaborate on projects and other investments that advance these benefits. TSMO strategies promote environmental benefits in a variety of ways:
The congestion management process conducted by metropolitan planning organizations (MPOs) provides an important connection between air quality and TSMO, especially in transportation management areas designated as ozone or carbon monoxide non-attainment areas.2
TSMO projects are often considered categorical exclusions in the National Environmental Policy Act environmental review process. This shortens review time and permits much quicker implementation than is possible with traditional expansion projects.3
The Congestion Mitigation and Air Quality Improvement (CMAQ) Program, administered by the Federal Highway Administration, provides funding to eligible surface transportation projects and other related efforts that contribute air quality improvements and provide congestion relief. TSMO projects can reduce emissions rates in many situations and are frequently eligible for CMAQ funding.
