The Adjustment Method of Bus Lines along New Subway after Operation

In order to adapt to the passenger demand after urban subway new line operation, and improve the operational efficiency of the bus lines along subway, the adjustment method of bus lines is studied. Taking the HuangHe Rd. segment with Dalian Metro Line 2 as the research object, the passenger volumes of every main traffic mode before and after subway operation were investigated respectively. By mathematical statistics method, the characteristics of passenger volume transferring among the bus, car and subway before and after operation were compared and analyzed. Based on the theory of random utility, not only the Logit model of traffic mode selection before and after subway operation was constructed, but also the calibration method of model parameter was proposed. The adjustment method of bus lines along subway was proposed. The calculation and analysis of application in the case was also conducted. The research indicates that, after subway operation, the passengers undertaken by car and bus along the subway will be attracted by subway to some extent. To adjust the bus lines according to the characteristic of passenger transferring can improve the operational efficiency of the bus lines along subway
