This project will develop a tool comparing incremental cost for incremental reductions in greenhouse gas (GHG) emissions, particularly for evaluating electric-propulsion vehicle systems. It will generate detailed inventories of GHG emissions for various vehicle types and catalog fuel-energy consumption reductions for various vehicle operational strategies (idling reduction, eco-driving, reduced deadheading, etc.), maintenance activities (tire inflation, rebuild schedules, etc.), and vehicle technologies (auxiliary power units, regenerative braking, gear-shifting algorithms, etc.). This project will propose a methodology for use by transit agencies in comparing GHG emission reductions from various propulsion system technologies available for bus fleet vehicle replacement purchases and rehabilitation, as well as from operational strategies and maintenance activities. Effective GHG-reduction measures can be expected to reduce energy costs. The primary research product will be a user-friendly tool for estimating comparative GHG reductions of various bus propulsion technologies. |
