A Framework for Optimizing Public Transit Bus Fleet Conversion to Alternative Fuels

Alternative fuel buses (hybrid-electric, battery-electric, compressed natural gas, etc.) have great potential to reduce lifecycle energy use and criteria pollutant emissions from urban and rural transit fleets. However, market penetration of alternative fuel transit buses in the U.S. is currently below 50%. The goal of this study is to develop an analytical framework to automatically generate an optimal transit agency bus fleet replacement plan across all alternative fuel options, based upon a comprehensive assessment of agency routes and on-road operating conditions. The framework will integrate the Georgia Tech Transit Simulator and Fuel and Emissions Calculator (FEC), employ real-world operating conditions and eco-transit management of field operations. The research will include a complete assessment of charging strategies for specific vehicle designs, routes, and on-road operations must be included in optimization modeling. This project will help transit agencies obtain a reasonable estimation of fuel-savings and identify the most economically-efficient fleet purchase and vehicle-route assignments for mixed fleets for a twenty-year vehicle lifecycle
