In 1968, United Nation prepared conventions to promote the safety and vitalization of traffic to accomodate increased international business and personal activities. They are convention on rad traffic and convention on road signs and signals. These conventions define the shape, color and the operational guidelines of signs, marking and traffic signals. However, the Korean road traffic law enforces independently the manufactural and operational guidelines of those devices and marking. Due to different regulations described in those two, potential problem might be expected in terms of international traffic in the near future in Korea. This paper presents the academical comparison between these two different road traffic regulations established by the Korean legislature and United Nation. It suggests a list of researches recommended for the nation to be ready to integrate international traffic.

Beyond the millennium industrial development affects all of our life, and the growth of the automobile among them provides us with convenience of the living. One, however, was regarded as important to recognize the safety of the parking rather today than any past, getting together with the increasing auto population into the popularization gradually. It was needed to develope an active system and safety equipment in order to protect against an accident because there were so many accidents during the parking about which one felt relief. The objectives of this study was to develop a supporting structure with high static friction, adapt to various road environments, such as an unpaved road, a wet paved road, controling an angle, considering a portable and moveable device in order to prevent an accident during parking. As it mentioned above, the novel supporting structure had four strengths rather than a previous supporting structure, a practical new design (1998 084336 B60C) The implication of the study was the inspiration from warning of the parking accident almost 10 % of the total traffic accident in Korea, tries to find a solution to a problem in order to decrease the parking accident, in addition, makes it regulation ,and it was implied to the orientation about the popularization and the practical use of the new supporting structure which was developed

Assuming a completed Smart Highway road & communication environment that allows real-time information collection and transmission of road traffic condition ahead, the purpose of this study is to develop a plan for inducing a network-level safe driving pattern by providing road traffic condition and safety information to multiple drivers through a road information provision device. In this study, the device with a function that displays different colors according to the hazard level to the existing delineator has been named 'Smart Delineator'. Smart Delineator is a device that provides not only alignment information but also safety information for drivers to receive real-time warning information and intuitively recognize road traffic condition ahead so that drivers can respond. To examine the effects of safety driving inducement level on drivers, a simulation test was conducted using driving simulator as well as a satisfaction survey. The result showed that the Smart Delineator was able to identify the location of occurrence and affecting driving according pattern, either adhering to recommended speed or reducing speed according to the pre-defined hazard level.

Buses, one of the representative public transportation modes, are divided into a vareity of service types according to the purpose of operation, operating distance, and management agencies. Although bus-involved crashes may cause large amount of damage due to the higher number of passengers boarded on a bus, prior research has little focused on crash severity according to bus service types. This study aims to investigate factors influencing crash severity in bus-involved crashes and to present policy implications to reduce crash severity by bus service type. To do this, bus-involved crash data from the Traffic Accident Analysis System (TAAS) during five-year period are used. Ordered probit models for three types of bus service, i.e., city bus, suburban and express buses, and charter buses, are estimated to analyze the factors of accident severity. The results show that there are significant differences of factors affecting crash severity among the types of bus services while speed and road surface influence all the types of buses. In case of local buses, time of day, roadway alignment, and installation of a traffic signal are found to be statistically significant factors. Seat belt and road class have significant effects on injury severity of the intercity and express buses. Chartered buses have time of day, driving experience, seatbelt, traffic signal, and day of week as the significant factors. The results of this study are expected to contribute to the reduction of the crash severity by each bus service type.
