WEBINAR: Predicting Transit Vehicle Performance Using the Fuel and Emissions Calculator

NOVEMBER 5, 2014
9:00AM-10:00AM PST


Dr. Yanzhi “Ann” Xu


The Fuels and Emission Calculator (FEC) is a new, spreadsheet-­‐based tool developed by Georgia Institute of Technology for Oak Ridge National Laboratory and the Federal Transit Administration. The FEC facilitates the comparison of greenhouse gas and criteria pollutant emissions performance for a variety of transit vehicle technologies, across different operating conditions.

The FEC can use second-­‐by-­‐second vehicle operating data collected by GPS devices to estimate fuel consumption and emissions as a function of duty-­‐cycle and resulting engine load (a modal  modeling approach). Transit on-­‐road operations (idling and speed-­‐acceleration profile), road grade, and passenger loading, all serve as inputs to the model. The modeling approach gives transit agencies the flexibility to consider location and time-­‐specific operating and geographic characteristics when comparing vehicle alternatives.

In this webinar, speaker Dr. Yanzhi “Ann” Xu will provide an overview and demonstration of the FEC’s capabilities and potential applications as well as provide participants an opportunity to ask questions.
