An Assessment Model of Reducing Air Pollution Benefit of Urban Rail Transit

Abstract

Considering low pollution problem of urban rail transit, reducing air pollution benefit is proposed in this study. Based on analysis of structure of reducing air pollution benefit, benefit of decreasing air pollution are described under considering the air pollution of power station of urban rail transit. A case study of line 1 of Shijiazhuang urban rail transit is given to demonstrate these models. Results show that benefit of reducing air pollution is 13.247 million RMB in 2013. Benefits of decreasing air pollution are 14.1552million RMB depending on traffic mode choice. In addition, air pollution costs of power station are 0.9082 million which is only 6.42% of reducing air pollution benefit depending on traffic mode choice.
