摘　　要：选取来自国际学术期刊的论文,以概述形式对城市交通理论方法、实证分析等学术研究成果进行总结性介绍,旨在增强城市交通业界和学界对国际学术动向和研究热点的关注,促进学术交流。本期选取的论文名为《电动汽车对降低交通噪声和大气污染的共同效益》。论文通过对比香港地区轻型车辆和公共汽车全面电气化前后产生的交通噪声和大气污染,呈现了电气化在降低交通噪声方面的积极作用。研究显示,电动汽车替代燃油汽车后不同地区道路交通噪声有不同程度下降,不同车辆场景下NO_(2)和PM_(2.5)也降幅不同,这两方面的效益能够为城市居民身心健康带来积极效果。A review of selected articles from international academic journals is presented to summarize research findings,theoretical approaches,and empirical analyses of urban transportation.The aim is to enhance the communication between industrial and academic fields of urban transportation,highlight international research focuses,and promote academic exchange.The selected paper in this issue is titled“The Co-Benefits of Electric Mobility in Reducing Traffic Noise and Chemical Air Pollution”.This paper presents a comparison of traffic noise and air pollution before and after the full electrification of light-duty vehicles and buses in Hong Kong,highlighting the positive effect of electrification in reducing traffic noise.The results show that,after replacing fossil fuel vehicles with electric vehicles,road traffic noise in different regions has decreased in various degrees and NO_(2) and PM_(2.5) levels have also declined under different vehicle scenarios.The benefits in both traffic noise and air pollution have positive impact on the physical and mental health of urban residents.
