花蓮吸引了很多觀光人潮，包含國內外的觀光客，而現行的旅遊車票的需求遠高於旅遊車票的供給，導致旅客很難購買到前往花蓮的火車票，但，很多情況卻是火車列車上仍然有空位，這種情況顯示台鐵的配票比例是有問題的。首先，我們收集了花蓮站的回收票和應用重力模型去估計真實的座位分配比例，本研究發現台鐵目前的配票只是基於距離和及業人口，因此，我們分析了現居人口、及業人口、家戶所得和台灣各大城市距離花蓮的距離，我們提出了改良的重力模型，得出了更合理的配票比例。

Hualien is a must to most of tourists (domestic or foreign). The need of travel is much higher than current supplies. It is hard for a traveler to get a train ticket from Taiwan Railways Administration (TRA) to visit Hualien. But, in many cases, there still are several empty seats in the train indeed. This discrepancy indicates the distribution (endowment assignment) of tickets of TRA unsuitable. First, we collected the recycle train tickets of Hualien and applied to the gravity model to estimate current principle of seat endowment assignment principle. This study finds out that TRA seat endowment assignment only based on the distance and employed population. In addition, we introduced a more reasonable seat endowment assignment by modified gravity mode. We analyze the lived population, employed population, income of family and the distance of railway to Hualien for the major cities in Taiwan.
