In 2014, Trinity acquired Sierra Research, expanding its ability to provide a wide range of mobile source modeling and certification support services as described below.
Mobile Source Modeling Analysis
Our team has an extensive history with mobile source emission factor, emission inventory and vehicle simulation models - covering both model development and model application. Models include U.S. EPA's MOVES, MOBILE, and NONROAD series and the California Air Resources Board's (CARB's) EMFAC and OFFROAD series. We also develop customized versions of MOVES, MOBILE, NONROAD, and EMFAC to address specific clients' needs and have adapted and implemented a vehicle simulation model, VEHSIM, for a variety of applications.
Vehicle and Engine Certification and In-Use Compliance Support
We have considerable experience in assisting manufacturers in negotiating the complex process of applying for both federal and California emission certification. The assistance we provide ranges from reviewing certification materials and data and providing advice, to completing all required paperwork/electronic filings for a manufacturer. Trinity also has extensive experience working with manufacturers to resolve in-use compliance issues with the California Air Resources Board and U.S. EPA.
