Noise Pollution Loss Value Evaluation of Railway Transportation Based on Hedonic Price Method- The Case of Taiyuan City

Abstract

Noise pollution damages people's health and brings about value loss at the same time. This paper takes Taiyuan City as the research area, selects railway transportation noise as the research object, estimates the marginal implied price of noise, and then estimates the loss value of railway transportation noise pollution in Taiyuan City. The results show that: According to the monitoring results of railway transport noise, the maximum equivalent sound level of the selected residential sample points is 74dB, and the minimum equivalent sound level is 43dB. The noise of most residential buildings near the railway exceeds the Class 1 standard 55dB. In addition, there is a significant negative correlation between the railway transport noise and the unit price of residential buildings around the railway. The regression coefficient of the noise variable is -0.246%. The marginal loss of railway transport noise pollution is calculated according to the valuation formula. It is found that for every 1dB increase in noise value, the pollution loss value caused by noise pollution is 50.8 yuan/square meter, and the impact range of value loss caused by railway transportation noise pollution is about 500m.
