The smart card data stores the transit usage records of individual passengers. By using this, it is possible to analyze the traffic demand by station and time. However, since the purpose of the trip is not recorded in the smart card data, the demand for each purpose such as commuting, school, and leisure is estimated based on the survey data. Since survey data includes only some samples, it is difficult to predict public transport demand for each purpose close to the complete enumeration survey. In this study, we estimates the purposes of trip for individual passengers using the smart card data corresponding to the complete enumeration survey of public transportation. We estimated trip purposes such as commute, school(university) considering frequency of O-D, duration, and departure time of a passenger. Based on this, the passengers are classified as workers and university students. In order to verify our methodology, we compared the estimation results of our study with the patterns of the survey data.

Railroads made many contribution to modernization being developed so quickly as public transportation, but after middle of 20 century, its qualities are getting low because of focusing on the investment and development of cars and airplanes. Its role which is getting the excellent merits on the mass transportation, rapid transit. safety, state period, energy efficiency, and prevention of environmental pollution has been reconsidered. Element of horizontal alignment In an existing railroad line is needed as basic materials, when it will be improved or moved. If its design drawing was lost or damaged, it is impossible to recover. It is riot easy to repair for it as disasters. We must understand an existing railroad line to bring a function included a basic geography situation. In this studies we acquire, analyze. and handle the digital picture of railroads and then reappear shape of three dimension. But also we want to contribute to establish the facilities information choosing materials of existing railroad line in outputting the alignment element by reverse.

Light railway system has many characteristics of better accessibility, frequency service, low construction cost, reduced air pollution and medium capacity public transport etc. Light railway system as a urban transportation system has been glowing worldwide since the late 20th century. More than 300 cities around the world have light railway systems. Many medium-size cities in domestic site is planning the construction of light railway. This paper reviews the domestic and foreign light railway system.

This paper describes an energy efficient train control. In these days, the researchers develop the energy efficient railway technologies, such as energy storage system, energy efficient driving. Mass rapid transit (MRT) railways, which are an important means of public transportation in urban areas, have operational characteristics that include short headways, frequent departures and arrivals. Therefore, when multiple trains are operating in the same power supply system, it is important to synchronize the energy tractions and regenerations. This paper define the group of trains for energy saving according to a power supply. We analyze the current synchronized driving situations and estimate the effect.

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.

The challenge to be faced in public transportation today is to satisfy human needs with the least delay, with the smallest number of accidents, and with the most economic use of energy, space, materials, man-power and money. One possible solution may lie in city train system, including AGT system. Specially, Passenger space in AGT is important to balance the budget of layout with passenger's satisfaction. This study focuses on lay-out and space, comfort which should be considered from the conceptual design stage of the interior layout work. Traditionally, the interior layout of the passenger room has emphasized ridequality and style. However, as the train becomes more prevalent and versatile, the focus also tends to shift toward layout and space to have comfortable circumstances. After all, the purpose of this research focused on arrangement a rational interior layout of the train through ergonomics research. Finally, the key was ensuring the comfortable environment based on cultural background of the passenger.

The purpose of this paper is to present some main economic factors which influence Gaza Seaport. Without direct access to the international market, the Palestinian economy will continue its dependence on Israeli economy mainly in employment, transport facilitation, and international trade. The greatest potential for Palestinian economic growth lies in trade. The port is important for creating new job opportunities, and for enhancing exporting capabilities, which are the most essential elements for development of the Palestinian economy. Israeli policies and procedures incur Palestinian exporters additional transportation costs when delivering their products to Israeli Ports or when transit these products to neighboring countries through Israeli controlled area. The public profit for the port is greater than the private profit. Therefore, constructing the port will have a great effect on the Palestinian economy. There are many challenges facing the port, some of them are the political stability, the economies of scale, and Israeli security measures and procedures.

There has been an increasing demand of introducing innovative public transport modes meriting high flexibilities of a bus mode along with on-time accuracy and quality environment-friendliness of a rail mode, as it is considered to significantly contribute to reducing huge social expenditures on the traffic congestion and environmental pollution agenda, and to be an alternative solution to better the urban transport problems. In order to comply with the need, Seoul Municipal Government has recently decided to build up GRT system of a new concept in Nangok area in Seoul, the first in its kind in Korea. The concession has been awarded to Seoul Metro. This thesis will study and benchmark similar systems abroad under operation, and further review necessary requirements overall which would secure full readiness for the operation of Nangok GRT system.

The Seoul Metro has been playing a vital role in public transportation for last 35 years as the feet of 10 millions of Seoul citizens. It currently takes charge of over 45% of the national subway transit and transports 4 millions of citizens a day. The purpose of this study is to suggest a plan for crew members' working condition improvement and job satisfaction improvement which will lead to the finest quality of service to the citizens. We examined the working conditions of the crew members and surveyed crew members about the working conditions and the extent of job satisfaction. The results of our study can also be used as basic materials for building the road map to the management improvement.
