구간과속단속시스템은 시점 순간속도, 종점 순간속도, 구간 평균속도를 측정하여 가장 많이 과속한 부분에 대해서만 과태료를 부과하는 방식으로 관련 연구 자료에 따르면 해당 시스템을 적용한 도로에서 속도 및 사고 감소 효과가 있는 것으로 알려져 있다. 하지만 도로교통법에 따라 시스템의 대부분은 고속도로에 설치되어 기존의 연구는 고속도로 구간을 대상으로 수행되어 왔다. 본 연구에서는 관련법령 개정에 따라 일반국도에도 구간과속단속시스템의 설치가 확대될 것으로 예상 되는 바 일반국도 자동차전용도로인 국도3호선 성남이천로에 설치된 구간과속단속시스템을 대상으로 ITS 수집 및 운영 자료를 활용하여 설치 전, 시범운영기간, 단속이후로 구분하여 통행속도, 통행속도에 대한 표준편차 및 교통사고 감소여부를 분석하였다. 분석결과 설치 후 통행속도, 표준편차, 교통사고는 각각 13%, 25%, 70% 감소하여 구간과속단속시스템 설치가 사고감소에 기여하는 바가 큰 것으로 확인되었다.

본 연구에서는 고속도로 버스전용차로 단속시스템을 개발하여 현장 성능평가를 수행하였다. 영동고속도로 마성터널 입구 버스전용차로에서 조사한 결과, 버스전용차로를 위반하는 차량의 비율이 99%에 달하는 것으로 조사되었다. 하지만 현재의 경찰관에 의한 인력식 단속은 단속율도 낮고 불필요한 안전문제 및 지체를 발생시킨다. 고속도로 버스전용차로는 6인 이상 탑승한 9인승 이상 승합차도 통행이 가능하기 때문에 승합차량의 승차인원을 검지하는 기술개발이 필요하다. 조도에 관계없는 승차인원 검지를 위해 적외선 카메라를 사용하였고 짧은 차두시간을 감안한 신속한 영상처리 기법으로 YOLOv5 딥러닝 알고리즘을 사용하였다. 개발시스템 성능 검증을 위해 테스트베드 및 실 현장 평가를 실시한 결과, 테스트베드와 실 현장에서 각각 7%, 8% 오차를 나타내 만족할 만한 성능을 보였다. 본 연구 결과물을 현장에 적용할 경우 고속도로 버스전용차로 운영 효율화 및 단속에 따른 불필요한 지체를 감소시킬 수 있을 것으로 기대된다.

교통사고로 인한 여러 가지 사회적 문제들로 인해 정부에서는 강력하게 교통사고를 줄이기 위한 여러 가지 정책들을 시행하여 왔다. 이러한 결과들로 인해 최근 들어 교통사고 발생건수 및 사망자 수가 감소추세에 있다. 그러나 이러한 교통사고 감소를 위한 여러 가지 정책들을 시행하기 위해서는 비용이 수반되게 마련이며, 이에 대한 비용 대비 효과 평가도 이루어질 필요가 있다. 본 연구에서는 최근 교통단속에 투자되는 비용 가운데 단속효과가 입증된 무인과속단속시스템에 의한 단속과 교통경찰에 의한 인력단속의 경우를 단속이 없는 경우와 비교하였다. 그 결과 평균속도에서 설치전 조건이 평균속도 82.66km/h, 인력단속 조건이 70.57km/h, 기계적 단속조건이 67.85km/h순으로 높게 나타났고 통계적으로도 유의한 차이가 있었다. 또한 제한속도 위반율에서도 설치전 조건이 65%, 인력단속조건이 32%, 기계적 단속조건이 19%의 순으로 나타났다. 차종별로는 승용차, 승합차, 화물차의 순으로 평균속도 및 위반율이 높았으며, 차로별로는 1차로가 2차로에 비해 높게 나타났다. 이와 같은 결과를 토대로 사고율을 추정하여 투입비용 대비 편익을 측정하였는데 무인과속단속시스템 설치전 조건의 경우와 비교하여 연간비용대비편익을 추정하였다. 그 결과 교통경찰에 의한 인력단속조건의 경우 76,130,590원의 마이너스편익이 발생하였고, 무인과속단속시스템에 의한 기계적 단속의 경우 38,577,670원의 편익이 발생하는 것으로 추정되었다

In the past, Chinese arbitral system and Chinese arbitral associations were avoided by international society due to the cases which Chinese court rejected the recognition and enforcement of foreign arbitral awards based on rural protection. Especially Chinese court adjudicated to reject the recognition and enforcement of arbitral awards by interpreting public policy broadly. The abuse of public policy by court threats the existence of commercial arbitration system. Under this awareness, the author figured out Chinese court shows what kind of attitude about public policy of Chinese court in the present through analyzing the cases about rejection of enforcement in Chinese arbitral awards in order to analyze whether Chinese court still maintain the negative attitude like past or there exist changes with public policy which is one of the rejection reasons of recognition and enforcement in foreign arbitral awards as the central figure. Chinese court behaved in an uncooperative attitude about arbitral awards like that it reached a verdict to reject the enforcement of arbitral awards by reason of violation in public policy about several foreign arbitral awards at the beginning stage of establishing arbitration law. However, the situation of abuse in public policy was improved a lot by Chinese prime court which enforces pre-inspection system about judgment of rejection of enforcement in arbitral awards. So, there is no case about rejecting the approval and enforcement of arbitral awards by reason of violation in public policy by Chinese court except Yongning Co. case. Moreover, Chinese court got the trust and support from other countries through reinforcement of applied standard. However, Chinese court had been expressed concern from international society because they highly applied public policy and rejected to enforce arbitral awards in the recent case of Yongning Co.. Therefore, this study examined whether it is appropriate to apply public policy of Chinese court in the case of Yongning Co., and then I concluded that. Although Yongning Co. case is the first case which Chinese prime court agrees with public policy by reason of rejection of approval and enforcement in foreign arbitral awards, in my opinion, it doesn't mean that Chinese court has fundamental change in basic attitude and position about the approval and enforcement of foreign arbitral awards. Chinese court keeps the cautious uses of public policy in legal judgment of foreign arbitral awards and it looks like implementing the obligation in regulation of New York Convention sincerely.

According to the National Police Agency, point-to-point speed enforcement system is being installed and operated in 97 sections across the country. It is more effective than other enforcement systems in terms of stabilizing the traffic flow and inhibiting the kangaroo effect. But it is only 5.1% of the total enforcement systems. The National Police Agency is also aware that its operation ratio is very low and it is necessary to expand point-to-point speed enforcement system. Hence, this study aims to provide the expansion basis of the point-to-point speed enforcement operation through analysis of the quantitative effects and development the accident prediction model. Firstly, this study analyzed the effectiveness of point-to-point speed enforcement system. Naive before-after study and comparison group method(C-G Method) were used as methodologies of analyzing the effectiveness. The result of using the naive before-after study was significant. Total accidents, EPDOs and casualty crashes decreased by 42.15%, 70.64% and 45.30% respectively. And average speed and the ratio of exceeding speed limit decreased by 6.92% and 20.50%p respectively. Moreover, using the C-G method total accidents, EPDOs and casualty crashes decreased by 31.35%, 66.62% and 10.04% respectively. And average speed and the ratio of exceeding speed limit decreased by 3.49% and 56.65%p respectively. Secondly, this study developed a prediction model for the probability of casualty crash. It was dependant on factors of traffic volume, ratio of exceeding speed limit, ratio of heavy vehicle, ratio of curve section, and presence of point-to-point speed enforcement. Finally, this study selected the most danger sections to the major highway and evaluated proper installation sections to the recent installation section by applying the accident prediction model. The results of this study are expected to be useful in establishing the installation standards for the point-to-point speed enforcement system.

This article reviews some recent decisions of the Supreme People's Court (SPC) of the People's Republic of China (PRC) on the recognition and enforcement of several South Korean arbitral awards. It explains the implementation of the New York Convention in the PRC and in particular the so-called Report System under the current Mainland Chinese law and judicial practice. It identifies some deficiencies in the People's Courts' approaches to the application and interpretation of the New York Convention and argues that the Mainland Chinese courts should adopt the pro-enforcement principle in the determination of the relevant issues under the New York Convention. It proposes further enhancement of the Report System and that the current categorization of 'domestic, foreign-related and foreign' in the context of arbitration agreements and arbitral awards needs to be further reviewed and clarified by the SPC. Last but not the least, it recommends some steps that South Korean parties should take to enhance the enforceability of South Korean Arbitral Awards in Mainland China.

Objectives: The purpose of the Act is to comprehensively consider the legislative notice of the Enforcement Decree of the Serious Accidents Punishment Act for each important issue in terms of system, content, and execution. Methods: We examine the legislative notice of the Enforcement Decree of the Serious Accidents Punishment Act in-depth from the perspective of the effectiveness of disaster prevention, consistency of the legal system, and harmony with legal principles. Results: The proposed Enforcement Decree of the Act on the Punishment of Serious Accidents hardly resolves the uncertainties of the law, and there are many aspects that are unclear in the enforcement ordinance itself and that do not comply with constitutional principles. As a result, it is judged that it is difficult to for it to serve as an accident prevention standard due to its low predictability and that it will be difficult to achieve effectiveness in accident prevention. Conclusions: Ultimately, the law itself should be extensively reorganized in order to ensure universal and sufficient effectiveness, including the abolition of the Serious Accidents Punishment Act. In the short term, even the Enforcement Decree of the Act should be reorganized and supplemented in accordance with the law and safety principles.

In order to overcome the limitations of the mobile speed system for 1 lane, this study is used a multi-laser beam to develop a mobile speed measuring system, using a multi-phase beam. By using multi-laser beam, least squares algorithms and speed error processing algorithms were developed to improve speed accordancy and speed error rates compared to conventional mobile speed meters using a single laser beam. A field test showed that 80.0 percent of 3 lane and 87.0 percent of 4 lane were appropriate for the mobile speed system. With the development of the mobile speed measuring system, it is expected to dramatically reduce the accidents caused by the speed of traffic. It is also expected to effectively operate equipment and manage the cost by improving manpower and providing improved enforcement accuracy, by contributing positively to public institution and public affairs.
