The Federal Transit Administration has sponsored a number of alternative fuels projects over the past several years under the Clean Air Program. These projects have included compressed natural gas (CNG), liquefied natural gas (LNG), methanol, biodiesel, propane, self-contained electric, battery-powered, and other vehicles. Each transit system experimenting with alternative fuels has experienced various levels of ease or difficulty in implementation and operation. Although numerous alternative fuel projects have been completed or are currently underway, there has not been an attempt to synthesize all the available information into a guide to assist transit managers in the assessment, selection, and implementation of alternative fuel options for transit buses.
The objectives of this research were to develop (1) a guidebook to assist transit managers in the assessment, selection, and implementation of alternative fuel options for transit buses and (2) a spreadsheet-based computer tool to assist in the quantification of costs associated with the potential conversion to alternative fuels.
The audience for the guidebook and accompanying computer tool are transit-system managers who, while being quite knowledgeable about the transit industry, may not be familiar with alternative fuels and implementation issues. The guidebook and computer tool provide a resource for managers to use in responding to questions from the general public and governing board, and provide information for transit systems of various sizes and in various regions.
The final guidebook and spreadsheet-based computer tool with User's Guide have been published as TCRP Report 38
, "Guidebook for Evaluating, Selecting, and Implementing Fuel Choices for Transit Bus Operations". TCRP Report 38
