  • Since Intelligent Transport Systems(ITS) is a complex project combining technology and system of transportation, information and communication and civil engineer, it needs a specialized management activities. However, it is difficult to judge who has responsibility for a shoddy and fault construction since the role between project management and supervision is very ambiguous. The aim of this study is propose an efficient project management and supervision for ITS reflecting the characteristics of ITS. Therefore, we suggest a statistical models using nonlinear regression model to prepare the project management and supervision compensation criteria, hence, we choose the realistic and validation statistical model.

  • In this paper, the vocabulary-independent continuous speech recognition system for speech control of intelligent home-network is presented. This study suggests a conversational scenario of continuous natural vocabulary based upon keywords for recognition on natural speech command, and a way of optimizing the recognition system by constructing a recognition system and database based upon keywords.

  • The government have plans to improve the railway transport capacity and transport hub for the sustainable national transport and logistics system. Specially, there are much efforts to improve transportation capacity such as high speed transportation of rail freight, enlargement of BT train, development of double stack train, etc. between railway transport hubs. If the transport capacity between railway logistics hubs is increased as planned, we must increase the handling capacity of railway hub terminals. But there are limits to enlarge the terminal infrastructure because of investment scale, location circumstances and urban development plans. To ensure the capacity, with the minimum required enlargement of infrastructure, it is necessary to extremely increase the efficiency of terminal operations. For improving the efficiency, we have to introduce the efficient terminal operation systems based on u-IT and operation optimize technologies. In this paper, we analyse the issues and problems of railway terminals(including ICD) and suggest the concept of intelligent railway terminal and the construction components of technology.

  • Digital convergence means a service or new product which appeared through fusion of unit technologies in information and communication regions. In 2011, The Government introduced "IT Convergence Technology Prediction Survey 2025". Smart mobility is a main factor in smart city which is main example of convergence. A intelligent transport system(ITS) is a key factor of smart mobility. The conventional transport systems include road, car, signal systems. But the ITS is a transport system containing additional technologies such as electronics, control, communication to increase traffic safety and effectiveness of traffic facilities. In this paper, we described intelligent transport system related with our life.

  • Currently, ITS (Intelligent Transport System) system is supporting a variety of services to be enhanced traffic's efficiency and driver's safety as developing of information communications and network technology. High data transfer communications such as Wibro, HSPA and WAVE are used for providing ITS services, but there are some differences from specification and performance applied. So, users who are employing the communication systems to transfer data whatever they want to have been suffering from use. In this paper, it is proposed that user can use various high data transfer communication systems wherever environments they are in using adaptation of system change. Also, it is implemented performance of system which uses alternate communication scheme in mobile terminal based on embedded platform.

  • The city of Suwon has introduced various ITS services between 2001 and 2006 as an alternative to solve chronic traffic congestion in the city. After the successful implementation, there was an effort to evaluate effects from the ITS deployments. However, the effects caused from ITS implementations may be realized in many different ways. Therefore, this research effort was aimed at evaluating the effectiveness of ITS implements through the first and second phases in Suwon using reasonable and scientific methods. Based on results from the analysis of variables presenting traffic condition, surveys and economic evaluation, the implementation of ITS services in Suwon can be concluded successful. However, there is a need for efforts to maintain the effects produced from the successful introduction of ITS services through continuous upgrading the systems, intensive maintenance, and efficient operations.
