Hybrid Buses Costs and Benefits
ثبت نشده
چکیده
• Diesel exhaust contains ozone precursors, benzene, arsenic, dioxins, formaldehyde and other toxic substances and is a significant contributor to airborne concentrations of fine particulate matter (PM). Significant health impacts including lung damage and premature death are associated with exposure to fine particulate matter. It can also aggravate conditions such as asthma and bronchitis. Diesel exhaust has also been classified as a probable human carcinogen with no known safe level of exposure. 2

Comparison of In-Use Operating Costs of Hybrid-Electric and Conventional School Buses
Hybrid-electric school buses became available in the US through a national consortium designed to bring hybrid-electric school buses to market by creating enough demand among school districts to encourage manufacturers to invest in development of the technology. A number of school districts in the US joined the HESB project to purchase plug-in hybrid-electric school buses. Sixteen hybrid-electr...
متن کاملIn-use Fuel Economy and Emission Benefits of Hybrid- Electric School Buses in Iowa
It is much safer and more fuel-efficient to transport children to school in buses than in private vehicles. However, school buses still consume 8.2 million gallons of diesel fuel annually, and transportation costs can be a significant portion of school districts’ budgets. Children in dieselpowered school buses may also be exposed to higher levels of particulates and other pollutants than childr...
متن کاملAssessing the Costs for Hybrid versus Regular Transit Buses
The main reasons agencies consider hybrid transit vehicles are fuel savings and reduced emissions. Hybrid electric buses offer an attractive option and have the potential to reduce operating costs for transit agencies significantly. Wayne et al. (2009) estimated that use of diesel-electric hybrid buses in 15 percent of the US transit fleet could reduce fuel consumption by 50.7 million gallons o...
متن کاملIn-Use Performance Comparison of Hybrid Electric, CNG, and Diesel Buses at New York City Transit
The National Renewable Energy Laboratory (NREL) evaluated the performance of diesel, compressed natural gas (CNG), and hybrid electric (equipped with BAE Systems’ HybriDrive propulsion system) transit buses at New York City Transit (NYCT). CNG, Gen I and Gen II hybrid electric propulsion systems were compared on fuel economy, maintenance and operating costs per mile, and reliability. These comp...
متن کاملOptimal Capacitor Allocation in Radial Distribution Networks for Annual Costs Minimization Using Hybrid PSO and Sequential Power Loss Index Based Method
In the most recent heuristic methods, the high potential buses for capacitor placement are initially identified and ranked using loss sensitivity factors (LSFs) or power loss index (PLI). These factors or indices help to reduce the search space of the optimization procedure, but they may not always indicate the appropriate placement of capacitors. This paper proposes an efficient approach for t...
متن کاملEvaluation of battery requirements for hybrid and electric city buses
This paper presents an evaluation of battery requirements for hybrid and electric city buses. Technical specifications of recently developed lithium based batteries and vehicle simulation results are used as basis for the evaluation. The battery requirements are evaluated in terms of power and energy capacity, calendar and cycle life as well as costs. Conventional diesel, parallel and series hy...
