"...designed to help those considering the deployment of, or conversion to, alternative fuel buses. The guidebook and life-cycle emissions model spreadsheet (FuelCost2) are intended to aide individuals who, while being quite knowledgeable about the transit industry, may not be familiar with alternative fuels and implementation issues. The guidebook and FuelCost2 provide tools to simplify the process of developing an alternative fuel strategy by clearly identifying the issues, and the costs and benefits associated with the conversion to various available alternative fuel technologies. FuelCost2 life-cycle costs and life-cycle emissions spreadsheet is available for download in a Microsoft Excel format. Appendix C of TCRP Report 146 is the user's guide for the tool. The spreadsheet includes additional instruction for using FuelCost2. This report updates, expands on, and replaces TCRP Report 38: Guidebook for Evaluating, Selecting, and Implementing Fuel Choices for Transit Bus Operations."--Provided by publisher.
