摘要： 城市道路作为行人活动的重要场所，其空气质量与人体健康密切相关，而空气污染物对人体健康的影响与人体实际暴露水平有着密切联系. 本文根据污染物暴露的相关概念，分析了城市道路环境下污染物由机动车排放源到人体的过程和行人污染物暴露的影响因素，对比总结了国内外污染物暴露的研究方法及适用性，结合城市道路污染物浓度的分布特点和交通流量变化的峰值特性，根据利兹市的道路污染物排放数据，探讨了行人在不同时段的污染物暴露水平.

Abstract: As an important place of pedestrian activities, the air quality of urban street is closely related to the human health, and the effects of air pollutants on human health have a close contact with the actual level of exposure. According to the concept of exposure, the paper analyzes the process of the exhaust pollutants from vehicles to pedestrians and the influencing factors under the urban traffic environment, and compares the research method of the pollutants exposure at home and abroad. Combined with the distribution characteristics of pollutants concentration and the peak feature of traffic flow in urban street, the paper also discusses the level of pollutant exposure of pedestrian in different time on the basis of the data of pollutant emission in Leeds City.

Key words: urban traffic, urban street, pedestrian, vehicle emission, pollutant exposure
