An on-board tailpipe emissions instrumentation system was designed, assembled and tested as proof-of-concept for the University of Vermont's Transportation Research Center (TRC) Signature Project No. 2 real-world vehicle emissions data collection effort. This report summarizes the measurement systems status as of June 2009 and demonstrates that the study team can reliably collect on-board emissions/vehicle performance data. The purpose of the new instrumentation package is to collect real-world exhaust emissions for regulated (CO, HC, NOx) and unregulated (CO2, air toxics, particle number) pollutant species as well as vehicle operating parameters, all at 1Hz temporal resolution, while a test vehicle is driven on the road network in Chittenden County, Vermont. Future data collected using the on-board system will be used to model the modal emissions of alternative vehicles. This report documents (1) the instrumentation systems components and the research teams proposed data collection methodology; and (2) presents initial data sets collected by quantifying real-world emissions from a 1999 Toyota Sienna minivan that was used in previous studies conducted by the PI.
