Abstract: In order to solve the problems of diverse construction benefits of air overpasses in different regions and few construction benefits in some regions, based on the collected real-time data,a data envelopment analysis(DEA) model with five evaluation indexes of total complexity, hourly risk, all day risk, hourly flow and all day flow is established. The C2 R model in DEA method is used to analyze 10 regions in China. The results show that the benefit values of Zhoukou and Changwu air overpass reach the best state, which shows that this method can be used as a means to evaluate the efficiency of air overpasses in different regions.

Key words: air overpass, data envelopment analysis(DEA) model, super efficiency data envelopment analysis(DEA) model, benefit analysis, Matlab program
