Highway traffic safety evaluation of area on the basis of the accident rate has a limitation, thus its result is dependent on the exposure variables. It works an obstacle to decision making for effective budget execution. In this paper, we developed a methodology of taking simultaneously macroscopic exposure indicators into account in evaluating the safety using least squares method. The weight of exposure indicators to make up of highway traffic safety evaluation index is that accident rate per population, accident rate per registration vehicle and accident rate per length of road is 0.29, 0.52 and 0.19 respectively and calculated the highway traffic safety index of total local governments in Korea. The methodology to calculate highway traffic safety evaluation index proposed in this paper can be utilized in executing the traffic safety policies to increase the efficiency of investment about traffic safety budget.

The purpose of this study is to suggest improvement measures focusing on traffic accidents in apartment complexes that occur to children among life safety accidents. Roads in most apartment complexes are not "roads" under the Road Traffic Act. In addition, there is no mandatory punishment or regulations, so the perception of the danger of traffic accidents in apartment complexes is very low. Recent, traffic in automobiles and motorcycles is increasing in the apartment complex, and traffic accidents are frequently occurring due to low safety awareness for both drivers and pedestrians. Accordingly, this study attempted to identify cases of traffic accidents in children's apartment complexes and to present problems and improvement measures for accidents. Problems of traffic accidents through child traffic accidents The current affairs are meaningful in that they are aware of dangers to children, carers, and drivers, and suggest traffic safety measures in apartment complexes.

"윤창호법" 시행 이후 음주운전이 크게 줄지 않았을 뿐 아니라 최근에는 다시 증가하는 추세를 보인다. 이에 본 논문에서는 우리나라와 일본의 음주운전 법적 기준 및 법정 형량, 등을 비교·분석하여 시사점을 제시하였다. 현재 음주운전 사상사고가 지속해서 발생하고 있고, 아직도 음주운전의 처벌이 강하지 않다는 인식이 크다. 이에 해외 사례 등을 참고하여 우리나라 현실에 부합하는 새로운 대안을 마련하고자 하며, 나아가 미래 자동차 디지털화 시대에 맞춰 변화될 법 제도의 올바른 방향에 대하여 고찰하고자 한다.

Road signs serve guide informations for efficient traffic control and are regulated by Road Sign Regulation. But few road managers break the regulation because of civil complaint and cause driver's confusion. Also, as promote the road name guide signs and the new road signs on expressway, the driver's confusion being increased. This study analysis factors of driver's confusion, calculates limited information on road signs and specifies modes of driver's confusion caused by road signs. The traffic accident data during 3 years is calculated in order to see how much intimate connection between the road sign confusion and the traffic.

In order to prevent various accidents with construction machinery, Korea enacted the Construction Machinery Management Act to enhance safety. Until now, there has been a lack of systematic research related to traffic accidents with construction machinery. Therefore, domestic and foreign systems related to construction machinery were reviewed, and the current status was analyzed based on traffic accident data over the past 5 years to derive implications. It is necessary to ensure the safety of construction machinery by correcting institutional loopholes and preparing follow-up measures. In addition, it is necessary to create a separate traffic-safety education program for construction machinery operators to create an environment that can comply with safe road-driving methods and traffic laws.

Eight colors prescribed by the Enforcement Rules of the Road Traffic Act and the group standard were tested to secure the minimum recursive reflectance performance standards when drying and wetting. The results were calculated to be 260.8 (mcd/㎡·lux) when drying white and 154.6 (mcd/㎡·lux) when wet. Yellow was 67% compared to the white reflective performance when drying. Wet poetry was 79 % and 59 %, respectively. In the case of blue, it was 64% in the case of white versus 72% in the case of white. Wet poetry was 63 % and 72 %, respectively. The range of changes in reflective performance during wetting was higher than when drying, and the absence of glass grains was similar to the previous results. The new colors also have a standard value of more than 50% compared to the white color in red, orange, pink, light green, and green. Based on this, it was estimated that the minimum reflective performance criteria according to the color of the road markings would form the basis for the enforcement rules of the Road Traffic Act.

본 글에서는 도로교통소음을 예측할 경우; 소음영향평가시 계획한 도로변에 방음시설물의 설치여부를 결정할 경우, 그리고 방음시설을 설치할 경우에 그 방음 시설의 구조와 설치기준을 결정하기 위하여 적용할 수 있는 방음시설물에 의한 차음 효과예측법의 문제점과 해결방안을 언급하였다. 방음시설물의 종류와 구조 그리고 그 설치범위 등을 정확하고 공평하게 그리고 경제적으로 결정하기 위해서, 특히 환경영향 평가가 공정하게 실시되기 위해서는 국가에서 방음시설물 설치기준과 정밀 한 차음효과 예측법을 하나의 통일된 규정으로 확정하여야 한다. 이를 위해서는 본문 에 언급한 요소들을 참조하여 기존의 방음벽설치 지침을 대폭적으로 수정.보완하여야 한다. 그러나 보다 정확한 예측과 실세계에 근접한 소음값을 계산하기 위해서는 소음 원과 소음전파 공간환경의 특성을 고려한 연구가 계속적으로 이루어져야 한다. 그리고 도로교통소음을 공정하게 예방하기 위해서는 조속한 시일내에 이에 적합한 대상지역별 도로교통소음예방 규제기준값을 법규에 명시하여야 하고, 현재 교통로 주변에 주택을 건설하는 경우에는 사업자가 택지로 확보한 부지안에 설치하고 있는 방음벽은 최대한 소음원에 근접하여 교통로변에 설치할 수 있도록 관련규정을 개정 하여야 한다.

As the development automated vehicles(AV) actively progresses around the world, the demand for a reasonable and systematic evaluation method for AVs is increasing. Research on scenarios, evaluation procedures, and methods for evaluating AVs conducted in simulations and proving ground(PG) is actively conducted internationally. In contrast, methods and procedures for evaluations on real roads are still in their infancy internationally. Therefore, it is necessary to conduct research on evaluating AVs on real roads in preparation for future use of AVs. This study aims to define the basic direction for evaluating the driving safety of AVs on real roads. To this end, the evaluation direction and process of AVs were presented on the real roads, and qualitative and quantitative evaluation indicators were selected to evaluate driving safety. A total of 38 items were selected based on the Road Traffic Act as qualitative evaluation items for evaluating the driving safety of AVs on real roads.

VDF(volume-delay function) is one of the most important factor to improve the reliability of traffic demand estimation because it is for estimation of link travel time based on the traffic volume variation. Because VDF of link except for freeway is applied as the parameter of BPR(bureau of public road) of U.S., it causes to deteriorate the accuracy of traffic demand estimation. The purpose of this paper is to establish new parameter of VDF based on the real-surveyed traffic data in order to improve the problem of the existing VDF. We suggest the reclassification of road hierarchy, the approach of traffic survey, the estimating method of VDF parameter, and the improvements of new VDF application. The new VDF allows us to estimate more realistic traffic situation in parts of demand, travel time and path between origin-destination.

In the commercialization stage of level 4 or higher autonomous driving, the need for new legal system related to drive safely has increased in order to meet the improved level of technological development. Especially human drivers should not be legally accountable for road safety in the era of autonomous vehicles and thus safety standards for operation of autonomous vehicles are significant. To address this issue, the German Road Traffic Act was revised in 2021, adding provisions corresponding to the commercialization of self-driving vehicle of level 4 and in the similar context the Japanese Road Traffic Ac was amended in 2022. This Article draws implications for legislative discussions on driving-related responsibilities of driverless autonomous vehicle to ensure driving safety in Korea through recent amendments in Germany and Japan.
