“…With the continuous development of the economy and society, car ownership gradually increases (Dillman et al 2021 ), which is accompanied by increases in the concentrations of traffic-related pollutants (Zheng et al 2021 ). Exposure to traffic-related pollution affects the human respiratory system (Bai et al 2018 ; Brugha and Grigg 2014 ) and the cognitive and developmental nervous system (Basagana et al 2016 ; Sunyer et al 2017 ) and may cause damage to other organs and tissues of the human body (Bhaskaran et al 2011 ; Pang et al 2021 ; 2016 ; van Berlo et al 2010 ).…”

Traffic-related pollutants seriously affect human health, and the commute time to and from school is the time when students are exposed greatest to traffic pollution sources. Field measurements were conducted with hand-held instruments while walking along two selected commuting routes in winter and spring. The measured data were then compared with background monitoring data, and the respiratory deposition dose (RDD) was calculated to assess the exposure risk. Particulate matter intake from 2018 to 2020 was calculated. In winter, the average concentrations of PM 2.5 and PM 10 were higher in the afternoon than in the morning. The highest concentration was 2.94 times greater than the background value. The lowconcentration distribution area of the low-traffic route that is off the main road (route B) was more significant than that of the high-traffic route that is near the main road (route A). Moreover, the RDD of route B was consistently lower than that of route A, while the average annual amount of PM 2.5 inhalation on route B in 3 years was 16.3% lower than that on route A. Overall, route B is more suitable than route A for students to commute on foot. Based on the findings, a walking route located within a community is a good choice.
