PURPOSES: This study is to suggest the improvement for bus rapid transit system in Seoul METHODS: The maintenance cost for bus lane damages and plastic deformations are increased by bus passing speed, heavy bus weight, and climate change (localized torrential downpour, subtropical climate) and the accident risk has been increased. RESULTS: Recent analysis of pavement damage indicates that bus lane damage caused by heavy weight is overwhelming and it is urgent to prepare countermeasures. CONCLUSIONS : Pavement data of bus rapid transit system, bus transit numbers and pavement damage elements were analyzed. By analyzing pavement maintenance, design and construction, the countermeasures for the improvement of bus lane pavement and effective maintenance were suggested.

Due to the gravitation of the population to Metropoleis caused by the radical industrialization and urbanization after the 1960s. most Korean cities not only have shown the deformed urban structure, but also have faced many serious problems in the public transit system. Especially, the medium-sized cities as the center of the local life have been under the low level of public transit service because of their poor transportation facilities and inefficient operations. Under these conditions, this study aims at improving its level and quality in the local midium-sized cities by performing the following; . to suggest the new idea of the public transit policies for the medium-sized cities. . to develop the Bus Transit Management System and its related computer programs. . to apply the design policies and methods to the Suwon life-circle in order to evaluate their performance.

These days, in Korea, according to improving the standard living, people generally work 5 days a week and it results more leisure hours. On weekends or in specific season, travel to mountain region around the major city is much in demand, and, in case of public transportation, the demand exceeds the supply. So, people tend to go other places, even overseas, for their holidays. The situation in Korea reflects the needs for mountainous light rail transit system with the object of convenient and rapid transport of passengers. In this paper, the guideline for mountainous light rail transit planing is proposed, and the representative mountainous light rail transit system is analyzed to choose the proper mountainous light rail transit system which adapts the demand for transportation and the terrain in Korea.

The Purpose of this study is to find out the renewal methods of Dae-jun railway station areas, focusing on the domestic/foreign case studies of the railway station areas and the possibility of the Industry-University-Institute collaboration in this area. As a result, this study shows that the revitalization for the impact area around rail transit station in the aspect of urban spatial structure, mixed land use, type of facilities and exchanging transit system of mass traffic etc, as well as such non-physical aspects as Industry-University-Institute collaboration and administrative planning. It does so by strengthening ties between hardware and software studies of urban planning and University Facilities planning. Finally this study suggested the strategy for the renewal of impact area around the rail transit stations.

Many services have been served by the exiting subway systems since they have opened in 1975. But its efficiency and competition were going down because of the high construction cost and difficult connection with other transportations, etc. Otherwise, the light rail transit system is much lower construction cost than the subway and the high way building. Also those systems are good at the inexpensive operation cost, the fixed time and safety, the easy access. Recently, the several provinces are planning or advancing the light rail transit system because of these many benefits. Consequently, those system's economical feasibility analysis is required rapidly to show the resonable construction's cause and to get the private investment. This paper offers the system's economical feasibility through the several benefit analysis after the light rail transit system's construction.

With designing alignment of railway for urban rail transit, a greater attention is paid to the riding safety and the comfort of the passengers. Especially, cant, transition curve, minimum curve radius are considered as very important alignment factors for the curve. For the above alignment factors, in this study, comparative studies on the design criteria of foreign rail transit are conducted. And reasonable design criteria of the alignment for urban rail transit are proposed.

The safety of staff customers and of general Public in general viewed as one of the most important requirements in the urban transit. The maintenance CALS system for car of urban transit is a part of standardization and development of urban transit system, and We have been performed the establishment of maintenance CALS system from 2001 to 2005. The RAMS for management computerization system are utilized in a variety of CALS system for user's convenience and safety in maintenance. Ever since its inception though, the urban transit has searched for ways to improve reliability, availability, maintainability and safety of the railway subsystem. In this paper, This system include RAMS(reliability, availability, maintainability and safety) of the vehicles shall be enhanced in the future.

The Cable Transit has an adaptable center hole for accommodating a cable to be passed through the wall(bulkhead/deck). The Cable Transits Sealing System must have important character which seal and protect against fire, smoke, gas, water, etc and consist of natal frame, sealing system and the cable, insulation. In this paper, introduced our cable transit organic expansion sealing material system, fire-resistance test and test result, etc. We carry to fire-resistance test in according to FTP Code Part 3(IMO Res. A. 754(18)) for A-60 class cable transit and the test result for our cable transit sealing system was satisfied.

PURPOSES: In this study, as part of an effort to develop HUD for public transit, it is proposed that the decision of order priority of contents which will be disposed to bus drivers through HUD for public transit using AHP(Analytic Hierarchy Process) technique. METHODS: In AHP analysis method brainstorming, factor analysis, hierarchical structuring, and weighting analysis were performed by applying a classical analysis method. RESULTS: By the result of analysis it is shown that unlike car drivers, bus drivers prefer information related to bus intervals, bus stop, and door open and close to information related to vehicle running. Also, bus stop information and bus interval information were ranked as first and second place in order priority of HUD contents for public transit by experts. CONCLUSIONS: This method of selecting order priority of HUD contents for public transit can provide a basic foundation for selecting order priority of traffic information contents as well as other HUD contents.
