A Comparative Study on Setting Forms of Public Transport Priority Based on Sound Environment Impact Assessment

Abstract:

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 assessment of five setting forms of public transport priority is carried out under different background.Results show that 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.
