Abstract

To encourage the society to choose the public transportation system, it should comfort and satisfy people. Noise pollution in urban transportation systems is a risk that can endanger passenger health and affect their use of public transportation. Hence, this study investigates the effect of noise pollution on users’ satisfaction of Tehran Metro line 7 using a sound level meter to measure noise pollution in four stations, namely Sanat Square, Tarbiat Modarres University, Shahid Navvab Safavi, and Rudaki. The data was analyzed using noise measurement, and noise pollution is compared at four stations with noise contour maps.
