Available in PDF, EPUB and Kindle. Book excerpt: The focus of this interim fleet evaluation is to characterize and evaluate the operating behavior of Foothill Transit's fast charge battery electric buses (BEBs). Future research will compare the BEBs' performance to conventional vehicles. In an effort to better understand the impacts of drive cycle characteristics on advanced vehicle technologies, researchers at the National Renewable Energy Laboratory analyzed over 148,000 km of in-use operational data, including driving and charging events. This analysis provides an unbiased evaluation of advanced vehicle technologies in real-world operation demonstrating the importance of understanding the effects of road grade and heating, ventilating and air conditioning requirements when deploying electric vehicles. The results of this analysis show that the Proterra BE35 demonstrated an operating energy efficiency of 1.34 kWh/km over the data reporting period.

In 2015, NREL launched an in-service evaluation of 12 battery electric buses (BEBs) compared to conventional compressed natural gas (CNG) buses operated by Foothill Transit in West Covina, California. The study aims to improve understanding of the overall usage and effectiveness of fast-charge BEBs and associated charging infrastructure in transit operation. To date, NREL researchers have analyzed more than 148,000 km of in-use operational data, including driving and charging events. Foothill Transit purchased the BEBs with grant funding from the Federal Transit Administration's Transit Investments for Greenhouse Gas and Energy Reduction Program.

Download or read book Bus Transport written by David A. Hensher and published by Elsevier. This book was released on 2007-01-30 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bus is the most patronised of all land–based public passenger mode but is seen as a somewhat unglamorous means of supporting mobility and accessibility, in contrast to rail – heavy and light, yet offers so much to the travelling public as well as offering attractive sustainability opportunities. This book reflects the author’s perspective on issues of importance to the preservation and health of the bus sector. The twenty one chapters cover the themes of institutional reform, performance measurement and monitoring, service quality, costing and pricing of services including commercial and non-commercial contracts, travel choice and demand, integrated bus-based systems, and public transport policy, especially challenges in growing patronage.

Available in PDF, EPUB and Kindle. Book excerpt: Beginning in March 2017, Long Beach Transit began operating a fleet of 10 battery electric buses (BEBs) in its service area in Southern California. These electric buses, produced by BYD, are 40-foot buses that are typically charged overnight. Long Beach Transit is collaborating with the California Air Resources Board (CARB) and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) to evaluate the buses in revenue service. NREL evaluated the first year of Long Beach Transit's BEB fleet under Federal Transit Administration funding and published a report covering results from January 2018 through December 2018. CARB provided funding to cover a second year of evaluation. This report provides an update to the previous reports and is focused on the second year of operation from January 2019 through December 2019. Data are provided on a selection of compressed natural gas (CNG) buses as a baseline comparison.
Download or read book Assessment of Hybrid electric Transit Bus Technology written by Nigel N. Clark and published by Transportation Research Board. This book was released on 2009 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: TCRP Report 132: Assessment of Hybrid-Electric Transit Bus Technology provides decisionmaking guidelines coupled with a comprehensive life cycle cost model (LCCM) to assist transit managers in evaluating, selecting, and implementing hybrid-electric technology options for transit buses. The guidelines and the accompanying LCC model resulted from the gathering of site data coupled with a comprehensive review of both capital requirements and operating costs of hybrid-electric buses in comparison with those powered by traditional diesel engines. Information grew out of a sound, engineering-based, independent technical evaluation of the costs, performance, and reliability of hybrid-electric transit bus technology in actual service. The LCC model, contained on the accompanying CD-ROM (CRP-CD-71), allows the user to compare the total life cycle costs across several cost categories for up to 6 different "purchase scenarios." These scenarios let the user decide when the purchases will be made, the types of buses to be compared, the work load of the buses, and many other cost inputs in determining benefits and costs associated with alternative purchasing strategies.

Download or read book Cost Effectiveness Analysis of Quasi In Motion Wireless Power Transfer for Plug In Hybrid Electric Transit Buses from Fleet Perspective written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the costs and benefits associated with the use of stationary-wireless-power-transfer-enabled plug-in hybrid electric buses and determined the cost effectiveness relative to conventional buses and hybrid electric buses. A factorial design was performed over a number of different battery sizes, charging power levels, and f bus stop charging stations. The net present costs were calculated for each vehicle design and provided the basis for design evaluation. In all cases, given the assumed economic conditions, the conventional bus achieved the lowest net present cost while the optimal plug-in hybrid electric bus scenario beat out the hybrid electric comparison scenario. The parameter sensitivity was also investigated under favorable and unfavorable market penetration assumptions.

Download or read book County Connection Battery Electric Bus Demonstration Preliminary Project Results written by and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Federal Transit Administration (FTA) funds a variety of research projects that support the commercialization of zero-emission bus technology. To evaluate projects funded through these programs, FTA has enlisted the help of the National Renewable Energy Laboratory (NREL) to conduct third-party evaluations of the technologies deployed under the FTA programs. NREL works with the selected agencies to evaluate the performance of the zero-emission buses compared to baseline conventional buses in similar service. The evaluation effort will advance the knowledge base of zero-emission technologies in transit bus applications and provide 'lessons learned' to aid other fleets in incrementally introducing next generation zero-emission buses into their operations. This report provides preliminary performance evaluation results from a demonstration of four all-electric trolley-replica buses and two electric vehicle charging stations at County Connection in the San Francisco Bay Area. NREL developed this preliminary results report to quickly disseminate evaluation results to stakeholders. Detailed evaluation results will be published in future reports.
