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.

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.

Link attributes, such as speed, occupancy, and flow, are essential factors for transportation planning and operation. It is, therefore, one of the most important decision-making problems in intelligent transport system (ITS) to determine the optimal location of a sensor for collecting the information on link attributes. This paper aims to develop a model to determine the optimal location of a sensor to minimize the variability of traffic information on whole networks. To achieve this, a network sensor location model (NSLM) is developed to reflect discrete characteristics of data collection. The variability indices of traffic information are calculated based on the summation of diagonal elements of the variance-covariance matrix. To assess the applicability of the developed model, speed data collected from the dedicated short range communication (DSRC) systems were used in Daegu metropolitan area. The developed model in this study contributes to the enhancement of investment efficiency and the improvement of information accuracy in intelligent transport system (ITS).

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.
