Research on Evaluation Method of Gas Environment in Metro Station

Abstract

Abstract With the development of rail transit, subway has become one of the main means of transportation in most cities. However, the particularity and tightness of the subway station, the continuous growth of passenger traffic has also brought some negative environmental problems, such as the comfort and safety of subway station staff and passengers. In this paper, a comprehensive evaluation model of gas environment for metro station is proposed. The micro environment quality evaluation index of metro station is divided into two parts, one is the air quality evaluation index, the other is the thermal comfort evaluation index. From the construction and calculation of these two indexes, the comprehensive evaluation of gas environment of metro station is realized. In order to verify the applicability of the proposed method, we collected the environmental parameter data of six subway stations and evaluated them by using the environmental assessment method. The results show that the proposed method can not only realize the evaluation and monitoring of the station environment, but also has great significance for the improvement and decision-making of public transport environment.
