Abstract: Power consumption is one of the main operating costs of urban rail transit system. Analysis of power consumption indicators plays an important role in the establishment of improvement measures, deepening and optimizing the evaluation of line network. The energy consumption level of various urban rail systems in 27 cities in China during the period from 2015 to 2017 is calculated, and the power consumption index statistics of metro lines that adopt different vehicles in different cities are carried out. Finally, the impact relationship of route laying mode, passenger personkilometers, load intensity and load rate of metro lines are analyzed according to statistical data.
