Open road tolling (ORT) design has been considered as an effective means of smoothing highway traffic and reducing travel delay on toll highways. In this paper it is demonstrated that ORT can also achieve significant air quality benefits over the conventional toll plaza design. The near roadside carbon monoxide (CO) concentration levels can be reduced by up to 37%, and diesel particulate matter (DPM) emissions can decrease by as much as 58%. These large expected air quality benefits have great implications to the regional efforts of reducing mobile source air pollution toward achieving attainment status and healthier living environment.
开放式道路收费（ORT）设计被认为是疏导高速公路交通和减少收费公路出行延误的有效手段。本文证明，与传统的收费站设计相比，ORT还能显著改善空气质量。路边一氧化碳（CO）浓度水平可降低多达37%，柴油颗粒物（DPM）排放量可减少多达58%。这些预期的显著空气质量改善成果，对于区域减少移动源空气污染以实现达标状态和营造更健康生活环境的努力具有重大意义。
