Conclusions
This study has proposed a comprehensive analysis approach for the comprehensive analysis of the traction energy
cost intensity and the passenger transport efficiency of an urban rail transit train by utilizing train traction
calculations and computer-aided simulations. The CEI is defined to evaluate the general cost of a train for its
transport. The optimized transport schemes with changing the formation scales and traction capacities of trains
operating on the same rail line are able to decrease the TEC of the daily operation of an urban rail transport line
without diminishing its service level. Due to data limitations, this research only studies one type of metro trains
operating on a certain rail line. Future study will pay more attention to different types of trains and rail lines to valid
the outcomes of this work.
