The phenomenon of large flow of metro passenger has been showing a trend of normalization， which has been causing an increasing attraction of the trip mode of metro to commuters in big cities. The large flow of metro passenger which has a great impact on passenger perception is becoming more and more obvious in metro hubs which are the nodes of metro network. The passenger will feel fatigued when they walking in the condition of large passenger flow in metro hub because of the extra energy expenditure of looking for entrance， the queue and the jam. The fatigue of passenger was reflected by energy expenditure in this paper. After analyzing the data of commuter energy expenditure obtained by designing the experiments in metro hubs， the result was got show-ing that the factors of initial status of commuters， body weight of commuters， gender of commuters and crowding of metro hubs had greater influence on passenger perception. Strategies of improving passenger service in metro hubs were proposed based on reducing passenger energy expenditure and enhancing passenger perception level.
