Subway Station Selection Model Based on Utility Combined Analysis

The subway station is the important node of the subway traffic net. The traffic volume of the subway station directly influences the programming of the subway net and the disposal of subway stations. When the subway net is dense, and there are several selections of the subway stations for the passengers, the selection result of the stations is directly related to the attraction of the station. In order to calculate the traffic volume of the station, the attraction of the station is needed. Therefore the method of utility combined analysis is used in this paper to calculate the station attraction. The values of every level of the characters are calculated according to the compositor of the stations, and then the attraction of the station is got. Combing the total subway volume of the traffic zone, the final volume of the station is got. The results show that the method is efficient in calculating the attraction of stations, and can provide basis for forecasting the traffic volume of the subway station.
