| Abstract |
Accurate demand estimating process in the construction of urban railway is very important, and precise validation is required. Existing model formula in the 4 phase model is limited in the estimation of the demand the administrative boundary-based zone system reflects no spatial railway demand characteristics around railway stations. The purpose of this study is improving the accuracy of urban rail demand estimation through segmentations of station influence areas and modal split characteristics within the areas. According to the case analysis, it is possible to set up the ststion influence area with a radius of 500m in the urban region and 1,000m in the suburban. And eastablishing proper segmentations of the ststion influence area shows more accurate results to the real demand of railway stations. |
