김규현,Kim, Gyuhyun 한국자동차안전학회 2020 자동차안전학회지 Vol.12 No.1

Personal mobility, which was used exclusively for leisure activities, has recently been used as a means of transportation, and it is expected to increase its role as the next generation transportation. Sales of personal mobility are increasing rapidly, but the problem is that traffic accidents are also increasing. In this study, human body injury caused by various collisions between electric wheel users and road users that occur on bicycle or pedestrian roads mainly used by personal mobility is analyzed through collision analysis and collision risk analysis. In the case of the collision accident for electric wheel, it is analyzed that the road users are more likely to be injured on the pedestrian road than the bicycle road. In addition, the head hit each other or fall and hit the floor caused severe head injury.

The Korea's safety standards for vehicle have been strengthened to reduce casualties from traffic accidents since 1962. The standards have a rather complicated structure. The safety standards are composed of the main text and asterisks, and the safety standard implementation rules are composed of the main text, asterisks and appendices, and items of the same name are stipulated in other chapters within the safety standards. This study is to suggest improvement measures such as simplifying the structure of these safety standards and integrating safety standard items with the same name. Through this, users' understanding of the standards will be improved, and it is expected that the system will be more efficient such as securing safety quickly through harmonization with international standards following the development of rapidly changing new technologies such as automated vehicles.

The purpose of this study is to conduct various crash tests of cars in domestic service and measure the deformation and body decelerations of vehicles. A relationship between impact speed and cars damage data such as deformation, body decelerations and etc are analyzed. The characteristics of crash tests of car in domestic service are obtained and will be used for developing a precise accident reconstruction program recorded such as Automatic Accident Recording System(AARS). In this study, the test results of the full frontal impact and side impact are reviewed. The results show that the decelerations of cars in domestic service are decreased on the increment of the vehicle weight. But duration of decelerations is increased on the increment of the vehicle weight.

The pedestrian-vehicle traffic accident is a globally recognized safety concern. UN/ECE/WP29 established Global Technical Regulation(GTR) for pedestrian safety on 12 November 2008. GTR is expected to significantly reduce the injuries of pedestrians in the case of the frontal impacts. Recently, a new pedestrian lower legform named Flex-PLi has been developed for the body model of the human lower leg. Flex-PLi is introduced and the characteristics of the model are identified by a comparison study with an existing lower legform. Usability, durability and repeatability are evaluated by using real vehicle impact tests. Moreover, the model is examined for the possibility of application to the pedestrian safety GTR phase 2.

In 1999, Korean New Car Assessment Program(KNCAP) was initiated with the primary purpose of providing consumers with a measure of the relative safety potential of vehicles in frontal crashes. The side impact test was added to KNCAP in 2003. Nine compact passenger cars, four medium passenger cars, three SUVs and two Vans were evaluated and the star ratings for the side impact tests have been reported. According to the test results, the dominant factor for the good star rating is the rib deflection of the EuroSID1. All SUVs and Vans with R-point over 700 ㎜ get five stars.

In this paper, we propose a navigation algorithm for high - precision measurement of the motion of an underwater vehicle through data fusion between an optical system, which is a global area sensor, and an IMU sensor, which is a local area sensor. Navigation algorithm is based on the Kalman filter structure and the results of two navigation algorithms with different IMU integration methods are compared and analyzed in a simulator of a dynamical based underwater vehicle simulation environment to evaluate the algorithm performance.

Bridge rails are usually installed on the curb with a specified height and width. The variance of the height and the width of the curd could affect the safety for the passengers and the behavior of the vehicles. In this study, the impact severities of passengers and the behaviors of vehicles are investigated according to the variable location of the bridge rails on the curb with the specified height and width. The full scale crash test results show that the impact severities such as the THIV and the maximum PHD are minimized in the case of the correspondence of the face of bridge rails and the curb. Also, the results show that the behaviors of the vehicles are stable.

The reconstruction of crash accidents is important to examine the cause of traffic accidents. For this purpose, the data for the delta v and deceleration of the vehicle, a driver's status and the environment of road and facility is a prerequisite. The characteristics of domestic cars in crash tests are obtained and will be used for the purpose of the crash accident reconstruction. Also, the characteristics are used for the method development estimating the impact speed through investigating the damage of cars. In this study, the test results of the full frontal barrier crash, the 40% offset crash, the center pole frontal crash and the 30 degree oblique frontal crash are reviewed and examined. The results show that the damages and the decelerations of various cars are increased in proportion to the increment of the impact speed.
