Abstract
To achieve carbon neutrality, many regions have set electrification targets for bus fleets. However, the impact of low temperatures on electric bus (EB) operations is often overlooked, leading to operational difficulties. To this end, we introduce an EB replacement discount coefficient to quantify reduced range and slower charging under low-temperature conditions and develop a Bus Fleet Replacement (BFR) model for cold regions. A case study using typical cold-region data is conducted. Finally, we discuss the effects of individual and combined policies, and parameter variations on the electrification process. The results indicate: i) replacing buses with electric ones in cold regions does not significantly increase the life cycle costs; ii) EB price subsidies and annual operational subsidies effectively accelerate electrification, and most policy combinations further reduce social costs; iii) the model can adjust replacement strategies based on case data and parameter changes. These findings support optimal BFR strategies in cold regions.
期刊介绍:
Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution.
We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
