This is a representative sample of how TRIMMS is being used or cited at federal, state and local levels.

The Environmental Protection Agency (EPA) Office of Transportation Air and Quality (OTAQ).  This study conducts a sketch-planning travel activity analysis, using a combination of TRIMMS and MOVES emissions modeling to estimate potential emission reductions from combinations of travel efficiency strategies: http://www.epa.gov/otaq/stateresources/policy/420r14003a.pdf

Federal Highway Administration (FHWA) Office of Operations – Operation Benefit/Cost Analysis Desk Reference.  Chapter 4 lists  TRIMMS as one of 12  existing benefit-costs tools and methods:

FHWA, Office of Planning, Environment, & Realty (HEP) – Congestion Management Process (CMP) Guidebook.  The guidebook lists TRIMMS as one of the tools available to assess congestion management strategies: http://www.fhwa.dot.gov/planning/congestion_management_process/cmp_guidebook/chap02.cfm

The Environmental Protection Agency (EPA) Office of Transportation Air and Quality (OTAQ) used TRIMMS to conduct a comprehensive study to provide support for national policy-level assessments of transportation control measures (TCM) listed in the Clean Air Act and other strategies, such as road pricing and smart growth, to reduce emissions and vehicle miles of travel (VMT).  The OTAQ analysis employed TRIMMS to estimate the national potential reductions in VMT under a variety of scenarios through the period 2010-2050: http://www.epa.gov/otaq/stateresources/policy/420r11003.pdf
