Abstract

In alignment with climate change, the European Union endeavors to accelerate the electrification progress of the public transit system. In particular, Copenhagen in Denmark and Oslo in Norway develop a blueprint to have 100% public transit electrification by 2030 and 2028, respectively. In this study, the lifecycle approach is applied to explore the role of electric buses in the electrification progress of the public transport system in different European countries. To better model the energy/fuel consumption, we integrate the theoretical model of human thermal comfortable temperature into our proposed framework. We take into account the effects of weather, the daily operation characteristics, and the energy mix of different European counties, and evaluate the lifecycle environmental and economic performance of electric buses. The result shows that the public transportation system with both hybrid and electric buses can be good compensation between financial and environmental needs instead of using electric buses to replace all the conventional buses. Moreover, the operational plan of the public transportation system mixed with electric and hybrid buses may be adjusted according to the seasonal temperature variation so as to maximize the environmental benefits. Considering the different economic and environmental scenarios of energy sources, some EU countries would be able to reduce or remove the incentives for electric buses.

替代燃料公交车在欧洲公共交通电气化转型期的作用:生命周期视角
摘要为了应对气候变化,欧盟努力加快公共交通系统的电气化进程。特别是,丹麦哥本哈根和挪威奥斯陆分别制定了到2030年和2028年实现100%公共交通电气化的蓝图。在本研究中,应用生命周期方法探讨了电动公交车在不同欧洲国家公共交通系统电气化进程中的作用。为了更好地模拟能源/燃料消耗,我们将人类热舒适温度的理论模型集成到我们提出的框架中。我们考虑了天气的影响、日常运营特征和欧洲不同国家的能源组合,并评估了电动公交车的生命周期环境和经济性能。结果表明,混合动力公交车和电动公交车的公共交通系统可以很好地补偿经济和环境需求,而不是使用电动公交车来取代所有传统公交车。此外,混合电动和混合动力公交车的公共交通系统的运营计划可以根据季节性温度变化进行调整,以最大限度地提高环境效益。考虑到能源的不同经济和环境情景,一些欧盟国家将能够减少或取消电动公交车的激励措施。

期刊介绍: The International Journal of Sustainable Transportation provides a discussion forum for the exchange of new and innovative ideas on sustainable transportation research in the context of environmental, economical, social, and engineering aspects, as well as current and future interactions of transportation systems and other urban subsystems. The scope includes the examination of overall sustainability of any transportation system, including its infrastructure, vehicle, operation, and maintenance; the integration of social science disciplines, engineering, and information technology with transportation; the understanding of the comparative aspects of different transportation systems from a global perspective; qualitative and quantitative transportation studies; and case studies, surveys, and expository papers in an international or local context. Equal emphasis is placed on the problems of sustainable transportation that are associated with passenger and freight transportation modes in both industrialized and non-industrialized areas. All submitted manuscripts are subject to initial evaluation by the Editors and, if found suitable for further consideration, to peer review by independent, anonymous expert reviewers. All peer review is single-blind. Submissions are made online via ScholarOne Manuscripts.
