Now, the population and economical power is deeply concentrated to Seoul-metropolitan region, therefoere the provinces is so lagging behind and the country cannot get balance development. And, like metropolitan region, the more outer the living area of local wide-area city is spreading, the more serious wide-region transportation problems are. But the railroads near wide-area city fun seldom commuter train, so they cannot absorb the transportation demand of wide-area city metropolitan region. To solve above transportation problem, local wide- area cities try to make a subway or a light rail transit. But it is so difficult because the limit of public finance and original small capacity of light rail. In the paper, I propose 'Local city wide-area electric railways' system of the consortium of 'Local wide-city and province transportation union', Korean National Railroad (KNR) and local capital. A 'Local wide-city and province transportation union' operates commuter railways directly using the facilities of KNR, and local capital invests to the stations of above railways system. Therefore the commuter railway system around local wide-city region will be constructed quickly and the stations will be the strong point of local development and investment.

In this paper, a wayside signaling emulator systems developed for testing to carbone ATC/ATO/TWC systems adopted in SMRT(Seoul Metropolitan Rapid Transit Coperation) line 7, 8 is presented. Informations that are required to train movement with driverless, such as stations status, destination station, restriction speed and train modes are provided through the wayside signaling emulator. The developed emulator systems can be constructed to 1.5km testing tracks and the end points of track, are emulated to the arbitrary stations in SMRT line 7, 8.

Recently, Electronic Distance Meter(EDM) is widely used for the traverse surveying and trilateration net. In this study, the closed traverse network is precisely adjusted by simultaneous adjustment of the observed angle and distance, using the Electronic Total Stations (Set 3). And also, it is examined that each kind accidental errors appear observed angles according to the observed distance and the number of repeating angle. In addition to the result, of checking between the simultaneous adjustment, the compass rule and transit rule, simultaneous adjustment in combination of the observed angle and distance is more accurate and effective than other adjustment.

Vending machines to release single-use RF(Radio Frequency) transport cards at Seoul Metro stations are operated under unmanned facility and have release & charge function. This Paper introduces function, configuration of vending machine to release single-use RF transport cards, the basic concepts & overview about vending machine's operating system. And suggests programming procedure to develop OS image of Windows Embedded operating system which is onboard the main board's electronic circuitry.

Since PSD(Platform Screen Door) is set up at many subway stations, its design related to a safety becomes gradually important. Especially the intereference check with a running railway vehicle is the most important of performance indices. This study proposes a dynamic analysis models for the railway vehicle and rail. Some design parameters are considered in the models to find a correlation to the performance.

In 2004, railway safety law was established since intimidatory factors have increased for railway industry, such as high speed rail, urban transit extension, induction of new transportations. The projects for safety system establishment and guidelines are performed including the safety guidelines for station and platform. Therefore, in this study the safety rules are examined through investigation for stations

This study focused on developing strategies of cyber-compact city, combining compact city with information and communications technologies(ICTs), in order to enhance sustainable transportation. The cyber-compact city development is defined as a development that is able to reduce travel by ICTs and encourage people to use transit or non-motorized vehicles such as bicycles for ICT-induced travel (especially, discretionary travel) by compact and mixed land use. It can be achieved with combining cyber and compact strategies with respect to network, node, and area. For example, ICT network may use transit network facility, a transfer station may be a hub of ICTs, and transit influenced zone may work with ICT service area. We proposed three cohesive strategies for the cyber-compact city based on literature review and case studies on cyber and compact cities. The first strategy is a cohesion between public transportation and telecommunication network by centering on the two for national and urban spatial linkage structure. That is, cities or urban centers and its peripheral areas can be connected by rail network, and extra space of railway network can be used for constructing telecommunication network infrastructure. The second strategy is a cohesion between public transportation node and telecommunication node by building up regional and urban telecommunication centers near to or at main railway stations. For this strategy, telework centers and communication service centers should be established mainly at transfer stations. The third strategy is a cohesion between public transportation impact zone and telecommunication impact zone as transit oriented development.

The core of the transportation service, so-called Mobility 4.0 is the flexibility of the entire mobility and its implementation. By doing so, the most essential element is to build a platform to link a supply and a demand simultaneously. In other word, a comprehensive analytical framework is to be set with a data repository which can be periodically updated. With such circumstances, the entire trip chain including pedestrian movements is required to be thoroughly investigated and constructed at the viewpoint of the intermodal transit station. A few studies, however, have been attempted. In this study, the comprehensive analytical framework with the integrated mobility at intermodal transit station was proposed, which consisted of the three modules; 1) Data Repository Extracting from Smart Card DB, 2) Framework of Analyzing Integrated Mobility, and 3) Interpretation of the Integrated Mobility with GIS information and the other factors. A case study with the seven railway stations (Sadang, Sindorom, Samseong, Gwanghwanoon, Gangnam, Jamsil, Seoul Nat'l Univ. of Education) was conducted. The stations of the case study were clustered by the three groups with the statistical ground, and it is most likely to understand the effect of a variety of factors and a comprehensive data-driven analyses with the entire trip stages.

The particle matter concentrations in the subway stations should be monitored and controlled for the health of commuters on the subway system. Seoul Metro and Seoul Metropolitan Rapid Transit Corporation are measuring several air pollutants regularly. In this paper, the reliability of the cheap instruments using light scattering method is improved with the help of a linear regression analysis technique to measure the $PM_{10}$ concentrations continuously in the subway stations. In addition, a monitoring system is implemented to display and record the data of $PM_{10}$, $CO_2$, humidity, and temperature. To transmit and receive these measured sensor data, CDMA M2M wireless communication method is applied.

The City Complex Development and TOD originated from the Compact City are entrenched domestically. The New Urban Development such as these changes Structure of Urban space from the Automobile to the Public Transportation. Also, Transit-Oriented Development is drawing attention as sustainability because it has effects of Environment as Green growth. However, An empirical Study is insufficient about Influence Factors of Transit Oriented Development. Therefore This study sets up the Density spaced 1000m apart of Transit Oriented than the existing and did 7 Types considered of Accessibility, Complexity and Design Element according to the Factorial analysis. As a result, this study drew that (1) 'intraregional accessibility of public transit', (2) 'degree of development', 'pedestrian-friendly facility', (3) 'interzonal accessibility of public transit', (4) 'land-use of the city centre', 'complex using of rail station area', 'complementary public transit' are related 201 in number of the Subway stations according to the Multi-dimensional scaling.
