The aim of this study was to investigate the possible reduction of air and noise pollution due to the substituent of motorcycles and personal vehicles with bicycles by the theoretical phase and to compare the exposure of a cyclist to noise pollution in using different modes of transportation in the field phase. In the theoretical phase, different scenarios were designed based on a 25% and 50% reduction in the volume of motorcycles and personal vehicles separately, as well as a simultaneous reduction of 50% for motorcycles and personal vehicles. The effect of running these scenarios on reducing air pollution was investigated using emission inventory model and on noise pollution by CadnaA software according to DIN 45687 and ISO 17534 Series. In the field phase, the exposure of a cyclist to noise pollution in the use of different modes of transportation was investigated in two main and secondary routes based on the weighted-time average method. Considering the 64% share of passenger cars in the total volume of motor vehicle traffic in Tehran, the highest noise reduction is expected to occur in the scenario of 50% replacement of private cars with bicycles under which, the average sound level near the main thoroughfares and highways will decrease by 1.8 dBA and PM2.5 and NO2 emissions by about 11 and 1196 t/y, respectively. According to the field investigations, noise levels for motorcyclists, cyclists, drivers, and public transport passengers were far higher than for car drivers, which may be attributed to the loud background noise and lack of a control system such as a proper cabin. By replacing cars and motorcycles with bicycles, air and noise pollution will definitely be reduced and cyclists will be less exposed to pollution. Accordingly, exposure to air and noise contaminants should be considered as effective decision-making criteria when locating bicycle lanes.

自行车发展作为一种非机动交通工具对减少空气和噪音污染的影响——案例研究:德黑兰中部地区

本研究的目的是在理论阶段研究由于摩托车和个人车辆被自行车取代而可能减少的空气和噪音污染,并比较骑自行车者在使用不同交通方式时接触噪音污染的情况。场相。在理论阶段,根据摩托车和私家车的体积分别减少25%和50%,以及摩托车和私家车同时减少50%,设计了不同的场景。根据 DIN 45687 和 ISO 17534 系列,使用排放清单模型和 CadnaA 软件研究运行这些场景对减少空气污染的影响。在现场阶段,基于加权时间平均法,在两条主要和次要路线上调查了骑自行车者在使用不同交通方式时暴露于噪声污染的情况。考虑到德黑兰机动车交通总量中乘用车占 64% 的份额,预计在 50% 的私家车被自行车替代的情况下,降噪幅度最大,在此情况下,主干道附近的平均声级高速公路将减少 1.8 dBA 和 PM2.5和 NO 2排放量分别减少约 11 和 1196 吨/年。根据实地调查,摩托车手、自行车手、司机和公共交通乘客的噪音水平远高于汽车司机,这可能是由于背景噪音大和缺乏适当的驾驶室等控制系统所致。用自行车代替汽车和摩托车,空气和噪音污染肯定会减少,骑自行车的人也不会受到污染。因此,在定位自行车道时,应将接触空气和噪音污染物视为有效的决策标准。
