The floating population that is index to figure out dynamic activities in urban area will be important in urban railway planning, but it is not useful because it is collected by posterior method. This study aims to investigate factors influencing floating population. The floating population data that was collected in Seoul for a month in December 2013 is used as dependent variable, and the negative binomial regression analysis is used in modelling. The number of households, number of employees, number of subway stations, and number of bus lines variables are statistically significant in predicting floating population.

Today, ever growing population density in Seoul or areas near Seoul is problematic. To overcome the problem, the government tries to construct so called, 'New-towns'near Seoul to spread out the population over larger areas. But building new-towns created another problem of traffic between Seoul and New-towns. It can be solved if more public transportation systems such as urban railroads are constructed. In order to succeed in urban railroad construction, we have to make a perfect plan through in depth research on characteristics of the urban train and the construction site. In this paper, we propose a method to design the Decision Support Systems(DSS) using Geographic Information Systems(GIS) and Spatial Analysis for the planning of urban railroad construction.

In the major operation section of urban railway, there has been occurred habitual delay, and delay propagation and spread to consecutive trains. Therefore, this delay cause the increase of operation time and irregular operation, also the increase of crowd and inconvenience to passengers. The railway operation plan is a promise to passengers and must have reliability. In the case of high frequency urban operation, dwell time have considerable influence on operational headway, so it is very important to efficiently plan and control the dwell time at stations. In this paper, the survey of the research on dwell time for urban railways is presented. The practical estimation model for minimum required dwell time, and the numerical example and validity are proposed.

경제 제도의 전환기를 맞이하고 있는 중국은 20세기 마지막 20여 년간 빠른 경제 발전을 이루었으며 중국의 도시는 계획경제체제와 중국식 시장경제체제 하에서 독특한 발전 과정을 겪어왔다. 이러한 발전 과정에서 도시 간 물류의 유동과 상호작용을 가장 뚜렷하게 반영할 수 있는 것은 철도망과 철도 운수라고 할 수 있다. 특히 도시간의 장거리 수송은 철도를 위주로 하고 있으며 철도망의 발달은 중국 도시의 형성과 발전에 중요한 요인으로 간주되고 있다. 그러므로 철도망의 구조와 철도 운송 자료는 중국 도시체계의 공간구조를 이해하는데 적절한 지표라고 볼 수 있다.

This research, which was started with a need for constant monitoring to find out urban societies and spacial effects by urban railway after the opening, was intended to empirically explore urban and social changes by the opening of Daejeon City metro line 1st which would greatly affect the spacial structure of the city. For this goal, we expected the effect of urban subway on the city with academic consideration and precedent study. Monitoring results of the subway station areas of Daejeon City metro line 1st showed the opening of urban railway had an influence on the flow of urban plan and urban space structure through population, land use, total-developing areas, and land price change. In other words, as urban railway opens the number of population and population activities centered on the subway station areas, and these movements led to the expansion of the commercial areas. Finally, they caused the average land prices to rise. Likewise, urban monitering is significantly useful comprehending the generally time-periodic changes of cities and even conceiving the present cities.

Presently, because making process of train service plan consist of various constraint condition, for example structure of track, structure of track in station, train maintenance time and others for considering to be necessary of train management, it has been had extremely complex structure problems. For these reasons, it has big problems to compare analysis for various train service time-table. A study suggest methodology to choice service the most effective schedule and plan of train put before comparative analysis on making train diamond picture's expected effect of established possible various train time-table in making process of train service schedule for improving effectiveness and organization of train service schedule establishment. A study uses Line-Blocking theory for analyzing train service time-table and analyze example for regional train Sadang to Ansan section in 4line.

In a densely developed metropolitan area, the subway system is often constructed to address the mobility problems. Subway system was first introduced in Seoul in late 1970s, then Korean metropolitan cities began to adopt the system later. Subway systems not only resolve the mobility problems, but also interact with regional socioeconomic landscape. This study aims to find the association between the subway network and land rent within the subway catchment areas in Gwangju metropolitan city in a spaciotemporal framework. The analysis results indicated that proximity to the subway station and the size of nearest road were positively associated with the land rent. Also from a cluster analysis, it was found that the old and new Central Business Districts as well as stations at peripheral areas had distinctive land rent change characteristics. This empirical analysis indirectly proves the strong association between land rent and urban planning and also the positive relationship between land rent and transportation networks.

This study examines history, usage, and spatial change of Cheoldo Park and its significance in the park planning in the Japanese colonial period focusing on the concept of a sports park. Cheoldo Park was verified as the first newly planned park built during the Japanese colonial period and continuously appeared in the official planning documents with different names and areas as a new planned park. This suggest that changes of Cheoldo Park reveal the important conceptual transition in the park planning. Activities in the park were understood by analyzing news paper articles and pictures, while spatial changes of the park were analyzed through maps and aerial photos. Changes in a park planning process were examined through analyzing the planning documents and maps. Cheoldo Park was opened in 1915 as a supporting facility of the Yongsan rail company residence complex. As Cheoldo Park became one of the urban parks of Gyeongseong in 1925, it had functioned as one of the main sports complexes of Gyeongseong. Although a sports park was suggested as a new type of urban park in the 1930's park plan, the programmatic aspect of a sports park was not distinctly defined yet. Cheoldo Park was not regarded as a sports park in the 1930's park plan. As a sports park was distinguished from other types of urban parks pro grammatically in the 1930s, the city tried to transform Cheoldo Park into a sports park. In the park plan of 1940, with major spatial expansion, Cheoldo Park became Ichon Park to be a main large park and sports park of Gyeongseong. Cheoldo Park contributed to the establishing a new direction of modern park planning, shifting from planning focus on quantitative improvement to qualitative improvement of urban parks. It also provided a realistic model to implement the park plans to overcome various limitations of the Japanese colonial period.
