Impact of vehicle-to-everything connectivity on fuel economy
Zero-emission powertrains, connectivity, and automation are the future of automotive mobility, though their collective impacts on fuel economy is difficult to study. This paper develops a novel methodology to simulate the impacts of cooperative driving automation on battery electric (BEVs) and fuel-cell electric (FCEVs) vehicles. Enabling V2I connectivity for city driving resulted in fuel economy improvement of 6 % to 13 % for BEVs and 9 % to 15 % for FCEVs. Enabling aerodynamic drag reduction in V2V highway driving resulted in fuel economy improvement of 5 % to 32 % for BEVs and 5 % to 26 % for FCEVs. Sensitivity analysis on battery and fuel cell efficiency was conducted to determine how technological improvements could impact connected mobility. Improving powertrain component efficiencies decreased performance gains for V2I city driving while increasing performance gains for V2V highway driving. Fuel-cell efficiency improvements had greater impacts on connectivity gains than battery efficiency improvements. Vehicle testing should verify these results.
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.
