摘　　要：根据各类公共交通优先设置形式的声环境特性,选择道路公交专用道(BUS)、道路交通快速公交系统(BRT)、高架地铁(MR)、高架轻轨(LR)和高架低速磁悬浮(LM)进行声环境评价比选研究.首先分析了上述5种公交优先设置形式的噪声影响因素;然后选择了道路交通与轨道交通公交优先客运走廊的噪声计算方法,并确定了相关参数;在此基础上,进行了5种公共交通优先设置形式的噪声情景设置、噪声计算与对比分析.研究结果表明,在城市公交优先客运走廊上,公交优先设置形式对声环境的影响比客运量变化的影响大;在高峰小时客运量2.0～5.0万客运走廊上,轻轨具有声环境优势;在高峰小时客运量5.0万以上客运走廊上,地铁具有声环境优势;在声环境特别敏感区域,宜采用低速磁悬浮.According to the sound environmental characteristic of different setting forms of public transport priority,bus lane line,bus rapid transit line,elevated-rail-based metro rail,light rail,low-speed maglev are compared with each other.First,the sound influence factors of the above mentioned five modes are analyzed;then the sound level calculation method and its parameters are determined;Finally,the sound environment impact forms of public transport priority background. Results show that assessment of five setting is carried out under different the setting form of public transport priority has a greater impact on sound environment of the urban passenger corridor than passenger volume; the sound environment impact superiority lies in light rail in the case of 20-50 thousand rush hour volume of urban passenger corridor and metro rail in the case of 50 thousand above; in the most sensitive area, the low-speed maglev is the best choice.
