Fences and air curtains can effectively reduce fine dust entry into roadside bus structures, thus decreasing the exposure of passengers to particulate matter. In this study, bus stop structures that reduce the entry of fine dust formed or dispersed by vehicles was derived through simulation models. These bus stop structures consist of a fence that blocks particle entry from a relatively low position in front of the bus stop and an air blast structure that blocks particle entry from a relatively high position. Three bus stop styles were considered: a bus stop without a fence, that with a vertical flat fence, and that with a vertical curved fence toward the road. Among these styles, the curved fence model was superior to other models, and particle entry into the bus stop was estimated to be reduced by 15.5 % for the curved fence model compared with the model without a fence. After the selection of the fence model, three air blast structures were considered: canopy, wall, and fence types, which blast air from the ceiling of the bus stop, toward the direction of the road from the rear wall of the bus stop, and upward from the top of the curved fence, respectively. The canopy-type air blast structure was found to be the most effective in decreasing particle entry into bus stops, with a reduction rate of 88 % compared with the reference model without a fence and air blast system.

栅栏和气幕可有效减少细粉尘进入路边公交车结构，从而减少乘客接触颗粒物的机会。在这项研究中，通过模拟模型得出了减少汽车形成或分散的细小灰尘进入的公交车站结构。这些公共汽车站结构包括：栅栏，其阻止从公共汽车站前面的相对低的位置进入的颗粒；以及鼓风结构，其阻止从较高的位置进入的颗粒。考虑了三种公交站台样式：不带围栏的公交站台，具有垂直平整围栏的公交站台和具有朝向道路的垂直弯曲围栏的公交站台。在这些样式中，弧形围栏模型优于其他模型，并且估计进入公交车站的颗粒物减少了15。与没有围栏的模型相比，弯曲围栏模型的5％。选择了围栏模型后，考虑了三种鼓风结构：顶篷，墙壁和围栏类型，它们从公交车站的顶棚向公交车站的后壁向道路的方向吹送空气，以及分别从弯曲围栏的顶部向上。冠层型鼓风结构被发现是最有效的减少颗粒进入公交车站的方法，与没有围栏和鼓风系统的参考模型相比，其减少率为88％。和分别从弯曲围栏的顶部向上。冠层型鼓风结构被发现是最有效的减少颗粒进入公交车站的方法，与没有围栏和鼓风系统的参考模型相比，其减少率为88％。和分别从弯曲围栏的顶部向上。冠层型鼓风结构被发现是最有效的减少颗粒进入公交车站的方法，与没有围栏和鼓风系统的参考模型相比，其减少率为88％。
