Urban rail transit environmental impact assessment based on extension matter-element model

Abstract

Urban rail transit environmental impact level is affected by many factors. In the account of various factors, this paper established an index system for the overall assessment of urban rail transit environmental impact. Based on matter-element model and extension mathematical methods, an extension matter-element model was established to assess the level of urban rail transit environmental impact. Through correlation and level calculation, objective and accurate urban rail transit environmental impact assessment results were worked out. The analysis and computation results showed that this method with simple actual operation can effectively ensure the assessment quality and efficiency. © 2011 Springer-Verlag Berlin Heidelberg.
