According to the Intergovernmental Panel on Climate Change, combustion of petroleum-based and other fossil fuels results in the increasing atmospheric concentrations of $CO_2$ and other greenhouse gases (GHG's) and is a major contributing factor to global warming. This paper includes estimates of the energy and petroleum use and the GHG emissions caused by the transportation sector. It then examines the extent to which diversions to alternative modes may be possible. Estimates are made of the potential reductions in energy and petroleum use and GHG emissions resulting from diversions from conventional modes, to both low-speed urban and high-speed intercity maglev vehicle trips based on "well-to-wheel" (i.e. total-fuel-cycle) calculations.

The technology of high-temperature superconductive (HTSC) maglev trains has become mature and ready for a commercial use ten years after its first prototype was made by Jiasu Wang and Suyu Wang. However, an appropriate roadmap in applying it to the market is crucial for its success because superconductivity mystery remains veiled and public safety concern may prevent it from being used.

Making practical use of urban MAGLEV system which is tried by government includes technique development and railway construction. Because huge amount of money will be spent on this project, feasibility study is being carried out in order to check the feasibility and to devise the master plan in prior to making practical use of urban MAGLEV system. The key issues of feasibility study are possibility of technique development, economical feasibility, location of a model railway and the improvement of related laws and regulations. This paper shows the approach to solve these key issues.

Applications of superconducting technology in transportation is more straightforward than others, such as magnetic levitation (maglev) trains. A maglev train is of high speed & low power-consumption, environmental friendly and safe, accompanied by some drawbacks. This article will introduce the application of superconducting technology in the urban mass transport system, and the bottleneck of this application.

MAGLEV is the vehicle which can run in levitated condition by the electro-magnets, and the vehicle can run without any contact condition. In MAGLEV system achieving a high magnetic field for minimum weight is a noteworthy goal. Unfortunately the two aspects of this goal high field and low weight are contradictory. Suitable designs must be sought using optimization techniques. In this paper is a technique for designing a electro-magnet in terms of simple equation.

Due to excessive city's Traffic jam, which an energy and pollution problem of metropolis have risen seriouly, Many industrialized countries have developed many kind of new transportation system for the purpose of substituting the mass traffic. Maglev system has began the revenue operation from Japan and China recently and it is beginning highlighted the new system. We examined specification to be improved in the system and safety of maglev.

In this paper, CPM (controlled-permanent magnet)-type magnetic levitation system is designed and implemented. The CPM maglev system to be controlled consists of eight magnets with permanent magnet and electromagnet. The total weight of maglev module system is 1ton. The design procedure is also described and the result of this work is shown.

In this paper, an electromagnet which is used in maglev(magnetic levitation) clean lift is designed and described. The electromagnet is firstly designed by using FEM(finite element method) tool and the simulation results are presented. The nominal airgap is 5mm and the nominal current is 2A. Also, the nominal magnetic force is 200N. From the results, we can get the electromagnet as an actuator used in maglev(magnetic levitation) clean lift for LCD process.

This paper gives an overview and developing status of the on-board Automatic Train Control (ATC) System employed to control the Urban Maglev vehicle in Korea. In the construction of demonstration line for Urban Maglev Program, the Daewoo Engineering Company (DEC) has participated as a supplier of the whole ATC System since 2009. According to the contract with Korea Rail Network Authority, DEC is under progress for the development of the whole ATC system including Safety Integration Level (SIL) assessment from the ISA, which is followed by the international standards IEC62278, IEC62279, and EN50129. Once the Urban Maglev Program is completed successfully in 2013, the developed system will be the first localized whole ATC system which has SIL assessment and commercial operation experience in Korea.

In general, railway system uses wheels so detecting speed by tachometer. However, LRT(Light Rail Transits) stands out recently as alternatives transportation, and besides of that Maglev trains are emerged as an alternative means of transportation. Maglev operates above certain heights caused inability of the measurement by tachometer which used to detect speed of wheels. Velocity Detection Signal Device of Train Control System applied in "Train Control System Project of Pilot Line Construction for Urban MAGLEV Train" which is prepared ahead of opening in 2013. This paper, therefore, explains the function and operation principal of Velocity Detection Signal Device, and suggests installation method of velocity detection loop installed around the track.
