Most surveillance systems of urban transit are based on CCTV(Closed Circuit Television). However, there is limitation that the passive monitoring system using CCTV in urban transit surveillance system to monitor massive environment applies thousands of cameras and it depends on operator's instinctive judgement whether it happens an accident or disaster. Urban transit operation corporations try to introduce the intelligent technology to overcome these problems as mentioned above. The intelligent system can be organized various ways and made configuration for purpose and function. In this paper, we describe the configuration problems of the existing surveillance system and propose the proper intelligent system configuration for urban transit We expect that the proposed configurations are very helpful to introduce the intelligent technology for urban transit surveillance system.

The standardization of the urban transit maintenance system consists of BOM System, maintenance parts code system, and accident/trouble code system standardization. This paper is described only the result of BOM System, maintenance parts code system, and accident/trouble code system standardization. The results of standardization are using urban transit maintenance IT system and apply Expert System, RAMS System, and DATABASE contents of various kinds.

ATC(Automatic Train Control) system employed in Bundang urban transit is operated in accordance with automatic blocking equipment. Using AF(Audio Frequency) track circuits installed at a block section, the block signal is automatically controlled and the safety of train operation is supported. In this paper, we investigate the operation mode of bundang urban transit and analyze the operation algorithm of ATC on-board system.

Recently Light Rail Transit(LRT) systems, especially full automatic systems are strongly issued by many provinces and major cities due to it's own characteristic for economical, environmental and sufficient transportation capacity. But LRT design criteria should be modified according to Rolling Stock's properties. -size, arrangement of bogie and wheel, power of traction motor etc, This thesis suggest for basic standard design criteria of Rubber Tired Light Rail Transit system.

Outline of design procedures of Linear Induction Motor (LIM) for transit vehicle applications are presented. The design steps are based on the classical design method. Constrains specific for transit applications are discussed. Heuristic data obtained from the various LIMs are utilized to streamline the presented design steps.

To investigate the adequacy of maglev train system to future urban transport environments, first we derived minimum necessity requirements of the new-transit system by analyzing the issues in the urban transit management and new needs of transportation customers. Then the conformity of Maglev train to the requirements was examined. With respect to this adequacy analysis, policy directions and agenda of the making practical use of urban transit Maglev system' is proposed.

This paper suggests improvements in travel cost function of transit assignment model by analysing existing model. Two types of travel cost function are widely used for congested public networks. The one is used for strictly restricting public transport capacity. Another is non-decreasing function such as BPR function. In this paper, we analyse two types of travel cost function in case of intercity rail. The characteristics of intercity rail are different from those of public transit in urban area. Therefore travel cost function must be differently applied in each case.

Rail transport has grown over the Past decades, and rail networks have highly concentrated in urban area, and it is possible for rail passengers to choose a route anions a number of alternative routes. Analysis of factors influencing the choice of route, are required to estimate the rail travel demand of each route. In this paper, we describes route choice model for the transit assignment and characteristics of the route choice(i.e., by relative travel time and fares), and attempts to estimate travel demand of new rail transit based on the slated preference(SP) survey data of Nanko Porttown, which is located in Osaka, Japan.
