Boundary Station is an evaluation index that was not reflected in the Seoul Metropolitan Urban Railroad Connected Eare Allocation. Boundary station is a station located at the boundary point of two transportation agencies sharing the same route, and track operation methods are divided into business management and maintenance management. Until now, the Connected Fare Allocation has evaluated the boundary stations from the perspective of business management. Meanwhile, the integrated public transportation fee system requires the need to interpret the boundary stations from the point of view of maintenance management at the developmental level. This study was prepared a measure to quantitatively analyze changes in income with the introduction of maintenance methods in mind. The Change in the income of operation agency evaluated based on the daily transportation card data for the boundary stations of the four Seoul Transportation Corporation and KORAIL sections. This study is meaningful as a basic research for an analytical judgment that evaluates and allocates changes in transportation income of Seoul Metropolitan Urban Railroad in the future.

It is necessary to determine real path for urban railway users in order to allocate revenues between urban railway organizations. Out of several algorithms used to determine optimal routes, the k-path algorithm based on link-label has been utilized. However, this k-path algorithm has certain flaws. For example, optimal route can change depending on the travel and walking time, transfer penalty, and so on. Also, this algorithm cannot take into account the characteristics of users, who prefer express train to normal trains. In this paper, an algorithm is proposed to determine one single optimal route based on the traffic card data. This method also can search for an optimal path in conjunction with the railway timetable.

Since most of the urban railway operating agencies are established and operated by local governments, Public Service Obligation(PSO) is given priority. Therefore, free riding is carried out based on individual laws and regulations. In Korea, as the aging population goes, the increase in the number of elderly passengers on the urban railways is leading to a free rider as a big part of the fiscal deficit of the city railway operators. However, there have been no previous researches on free pass riding, and especially, it is necessary to study free ride on private investment projects. Several alternatives including a full charge case, free-ride for 70 years old over case, and separate fare charge (900won) are considered. Separate fare charge (900won) was selected as the optimal alternative since there is no fare income adjustment between operating agencies and no subsidy from government.
