With the expansion the Taipei MRT network, the ridership also increases annually. However, after the standardization process, the unit length ridership may not increase with network. Therefore, in order to analyze the effect for MRT network, the this research collected the overall ridership data from 1996.3~2006.12 and OD ridership data of each station from 1998.12~2006.12. T-test was used to analyze the effect between different expansion period, regression models were also built to construct the ridership effect for Taipei MRT network.
The results indicate that the unit length ridership of Danshui, Zhonghe Line increase while the expansion period from Danshui station through Zhongshan station, Taipei Station and Nanshijiao station. Furthermore, the unit length ridership of Muzha Line also increase with respect to the expansion process of Danshui, Zhonghe Line. The MRT network had not been formed until the construction of Bannan Line from Longshan Temple Station to Taipei City Hall Station. The connection of two parallel lines allows passenger to transfer between different lines, at the mean time, the unit length ridership increased comparing to the duration before the forming of MRT network. In addition, the analysis showed that the overall unit length ridership did not increase while Longshan Temple Station to Xinpu Station of BanNan Line, Ximen station to C.K.S. Memorial Hall station of Xiaonanmen Line, Taipei City Hall Station to Kunyang station of BanNan Line, Xiaobitan branch Line, Xinpu Station to Fuzhong station of BanNan Line and Fuzhong station to Yongning station of Bannan Line started commercial service. The results indicated that the expansion of network in suburban area did not have significant effect to the whole network. Moreover, this research also shows that unit length ridership tended to decrease after the network expand to 74.4 km.
Lastly, this research applied regression analysis to build the relation of MRT annual ridership and unit network length. The result showed that the model of cubic curve best fit to the actual unit network length of MRT. |
