Abstract

Improving urban dwellers quality of life requires mitigating traffic congestion, minimizing waiting delays, and reducing fuel wastage and associated toxic air pollutants. Battery-electric vehicles (BEVs) are envisioned as the best option, thanks to zero exhaust emissions and regenerative braking. BEVs can be human-driven or autonomous and will co-exist with internal combustion engine vehicles (ICEVs) for years. BEVs can help at complex intersections where traffic is saturated. However, their benefits can be reduced by poor intersection management (IM) strategies that coordinate mixed traffic configurations inefficiently. This paper studies energy savings and emissions reduction using BEVs mixed with human-driven ICEVs under eight relevant IM approaches. It shows that adding BEVs has impacts on throughput, energy consumption, waiting delays, and tail-pipe emissions that depend on the specific IM approach used. Thus, this study provides the information needed to support an optimal choice of IM approaches considering the emerging trend towards electrical mobility.

在一个孤立的复杂交叉路口使用 BEV 可实现节能减排
要提高城市居民的生活质量,就必须缓解交通拥堵,尽量减少等待延误,减少燃料浪费和相关的有毒空气污染物。电池电动汽车(BEV)具有零废气排放和再生制动功能,被认为是最佳选择。BEV 可由人类驾驶或自动驾驶,并将与内燃机汽车(ICEV)共存数年。在交通饱和的复杂交叉路口,BEV 可以提供帮助。然而,由于交叉路口管理(IM)策略不当,混合交通配置协调效率低下,可能会降低其效益。本文研究了在八种相关的 IM 方法下,使用 BEV 与人力驱动的 ICEV 混合行驶所产生的节能减排效果。结果表明,增加 BEV 对吞吐量、能源消耗、等待延迟和尾气排放都有影响,这些影响取决于所使用的具体 IM 方法。因此,考虑到电动交通的新兴趋势,本研究提供了所需的信息,以支持对即时通讯方法的最佳选择。

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.
