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, and elevated rail based Metro Rail, Light Rail, Low-speed Maglev are selected to compare with each other. Firstly, the sound influence factors of above mentioned five mode is analyzed; then the sound level calculated method and its parameters are determined; lastly, sound environment impact assessment of five setting forms of Public Transport Priority is carried out under different background scene. The main results of this research are: The setting form of Public Transport Priority has a greater sound environmental impact of the urban passenger corridor then passenger volume; the sound environment impact superiority lies in Light Rail to 20~50 thousand rush hour volume of urban passenger corridor and Metro Rail to 50 thousand more; in the most sound sensitive area, the Low-speed Maglev is the best choice.
