Advance Transit Air Quality Impact Analysis

Project Summary:

In 2005, the Upper Valley Transportation Management Association (UVTMA) completed a research report entitled Operational Impact Study of Advance Transit Fixed-Route Bus Network. The study, completed at the request of the Lebanon (NH) City Council, examined ridership trends, fuel consumption, air quality impacts, and evaluated the feasibility of instituting a fare structure. The study was based on Fiscal Year 2004 data, surveys, and analysis.

As part of the Operational Impact Study of Advance Transit Fixed-Route Bus Network, the Upper Valley Lake Sunapee Regional Planning Commission (UVLSRPC) developed an analysis of the air quality impacts of Advance Transit's fixed-route bus service. The analysis, also based on FY 2004 data, incorporated a four-step method for quantifying air quality impacts:

  1. Calculating the avoided Vehicle Miles Traveled (VMT) resulting from "choice" riders of Advance Transit's fixed-route services.
  2. Calculating the emissions correlating to the avoided vehicle miles traveled.
  3. Calculating the emissions of buses operating on Advance Transit's fixed-route services.
  4. Reconciling the passenger vehicle emissions avoided with the emissions of buses operating on Advance Transit's fixed-route services to determine a net air quality impact.

UVLSRPC staff utilized the U.S. Environmental Protection Agency's (EPA) Mobile 6.2 modeling framework, in consultation with the New Hampshire Department of Environmental Services (NHDES) Air Resources Division to quantify the emissions of three pollutants: Volatile Organic Compounds (VOC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx).

The 2012 Advance Transit Air Quality Impact Analysis presents an update to the air quality analysis developed as part of the 2005 Operational Impact Study of Advance Transit Fixed-Route Bus Network and is intended to provide comparative figures from FY 2004 and FY 2011.
