英文摘要	Traffic air pollution control is an important aspect of air quality management in urban areas. In this study, we investigated whether short-duration vehicular traffic control could be applied as a temporary tool to improve the roadside air quality based on concentrations of roadside volatile organic compounds (VOCs). Experiments were conducted targeting a 30-min “no-vehicle” event observed on 30th May 2019 (13:30–14:00) in Central Taiwan. Although the event was not imposed for air quality management, it provided an excellent opportunity to evaluate it as a potential tool of air quality management. Roadside air samples were collected before, during and after the no-vehicle event from two locations in Central Taiwan. Samples were analyzed for a total of 87 target VOCs. Results showed that alkanes, aromatics and oxygenated organics were the major contributors of roadside VOCs. Mean concentrations of the sum of detected VOCs (∑VOCs) were about 8%–24% lower during the no-vehicle event compared to those before or after the event. Correlation analysis showed that a total of 20 VOCs were related to traffic emissions. During-event concentrations of the sum of those traffic related VOCs were less than pre- or post-event concentrations by 40.77%–83.20%. Diagnostic ratios among VOCs revealed a notable impact of no-vehicle event on the composition and concentrations of the roadside VOCs. Although the short-duration vehicular traffic control had only a limited impact on ∑VOCs due to the presence of multiple emission sources, it had significant impact on the traffic related VOCs. © 2020 Turkish National Committee for Air Pollution Research and Control
