교통량의 급속한 증가에 의해 교통사고 발생건수는 34년동안 무려 50배가 증가하였다. 또한, 교통사고 사망자수도 매년 5.1%씩 증가하고 있다. 본 논문의 목적은 속초경찰서에서 실시하고 있는 음주운전 단속의 문제점 및 개선방안을 조사-분석하고, 사고지점의 도로환경이 전한가를 분석하는 데 있다. 본 연구를 통해 속초경찰서의 음주단속지점 위치가 변하지 않고 동일하여 많은 음주운전자가 있음에도 불구하고 단속이 제대로 이루어지지 않고 있다는 것을 알 수 있었다. 또한, 사례연구에서도 알 수 있듯이 단속시간이 야간에 편중되어 있어 낮에 이루어지는 음주운전에는 안일한 자세를 취하고 있다. 그러므로, 앞으로 단속지점의 변화와 단속시간을 늘려 음주운전자 및 음주사고를 줄여야 하겠다.

At present automated speed enforcement system in Korea control overspeed vehicle only in the specific spot. Because the drivers generally recognize the previous stated fact, they reduce a speed only in the establishment location of systems and increase rapidly again as soon as it passes the location. we have known that the rate of traffic risk at the tunnel, bridge and curve road segment is higher than other road section. Therefore, it needs speed control in them. In such a case, it is necessary to establish the automated traffic enforcement system based on the travel time speed of an individual vehicle over a pre defined stretch of road. In this study, the application limit of existing spot overspeed enforcement system was studied through an analysis of traffic flow characteristics in the tunnel, bridge and curve section. Also we found out the optimal distance of segment and the most suitable location to an application of the overspeed vehicle by travel time speed through an analysis of the road structure, traffic condition and accident numbers in the road.

Currently, in Korea, a multi-seater lane (HOV) and a designated lane system are being implemented to solve traffic congestion. However, in both systems, it is difficult to crack down on cases of violations without permission, so people are required to be assigned to areas that want to crack down. In this process, manpower and budget are inefficiently consumed. To compensate for these shortcomings, we propose the development of an integrated enforcement system through YOLO, a deep learning object recognition model. If the two systems are implemented and integrated using YOLO, they will have advantages in terms of manpower and budget over existing systems because only data learning and system maintenance are considered. In addition, in the case of violations in which it is difficult for the existing unmanned system to crack down, the effect of increasing the crackdown rate through continuous learning can be expected.

자동차 보급률 증가로 인해 교통 혼잡, 불법 주정차 등의 사회적 문제가 발생하고 있다. 특히 불법 주정차는 교통 혼잡, 주차 공간 부족 등 부가적인 문제를 발생시키고 있다. 따라서 각 지방자치단체에서는 불법 주정차 문제를 해결하기 위한 방안을 연구하고 있다. 그러나 이러한 방안은 초기 비용 발생 및 인력 부족 등의 한계가 있다. 한편, 정보통신의 발달에 따라 공공 업무에도 대량의 공공데이터를 효율적으로 처리하기 위한 연구가 진행되고 있다. 하지만 이러한 연구 또한 빅데이터 처리 플랫폼 부족 및 분석 시스템이 미흡한 한계가 존재한다. 따라서 본 논문에서는 불법 주정차 데이터와 같은 공공 데이터를 효율적으로 처리하기 위해, 주정차 단속 시스템을 위한 하둡 기반 대용량 데이터 관리 및 분석 시스템을 제안한다. 제안하는 시스템은 첫째, 주차단속을 수행할 때 주차단속 데이터를 하이브(Hive)를 통해 저장하고, 단속된 차량의 차주를 검색하여 단속임을 알리거나 과태료를 부과한다. 둘째, 웹 인터페이스를 통해 수집된 주차단속 데이터에 대한 다양한 분석을 수행하고, 분석된 데이터에 대한 R을 이용한 시각화를 제공한다.

The RLC systems is one of the intelligent transportation systems that has gained a nation-wide support for last decades and being installed to discourage motorists from running the red lights at signalized intersections. It is taken for granted that the RLC will provide motorists with increased safety, so that their installments are always justifiable. However, in order to acquire more efficiency and wider supports from the general public in future RLC installments, an improved methodology for analyzing the effects of the RLC systems is required. In order to satisfy this requirement, this research performed the following tasks. First, the number of signal violations after the RLC systems were investigated in order to check its resulting effects. Second, the number of crashes after the RLC systems were collected and compared with the number of signal violations. Third, a statistical analysis was carried out to develop the relationships between the signal violations and the crashes based on negative binomial distribution. The analysis revealed that the number of crashes has a close relationship with the RLC placement, traffic volume, vehicle speed, the number of phases, and the number of lanes for major approaches. Finally, based on the results found in this analysis, this research presents a methodology for analyzing the safety effects of placing the RLC that should be of service when investigating the economic consequences of the RLC systems.

The Korean government introduced an automated speed enforcement system (ASES), which uses traffic enforcement cameras, to counteract safety issues that are caused by speeding. As the information of the traffic enforcement camera locations is provided to the drivers via navigation systems and mobile applications in a timely manner, drivers can avoid enforcement by momentarily diminishing their speeds only near the camera locations. To prevent drivers' evasional behavior and improve the effectiveness of ASES, section control, which enforces speeding vehicles by measuring their average travel speeds over a stretch of road and checking against the speed limit, has been recently implemented. In this study, Section Speed Enforcement Zone and Comparison Zone are compared in terms of traffic stream characteristics under free flow conditions. To this end, loop detector data were obtained from the three study sites and analyzed. The study results demonstrated that drivers maintain their speeds below the speed limit over the enforcement section with a lower variance of speeds.

On January 16 to May 31, 2012, Korea Expressway Corporation was carried out an pilot overweight enforcement using high-speed weigh-in-motion at Gyeongbu expressway 195.0k (Gimcheon) and Jungbunaeryuk expressway 119.5k (Seonsan). In this study, it is attempted to analyze the practical effect of high-speed weigh-in-motion by comparing the average total weight and traffic volume of eight weeks before and after the these overweight enforcement, respectively. The main results are as follows: First, the result of analysis of the change in average total weight and traffic volume, it was found that it did not differ after as in previous traffic volume, and the total weight is reduced. This means that the total weight is not reduced by decreasing freight traffic, but by decreasing the total weight. Therefore, it can be seen that there is an effect of pilot overweight enforcement using high-speed weigh-in-motion. Second, the average total weight and total weekly traffic volume decreased rapidly starting from the start of the overweight enforcement, but there was showing a tendency to increase gradually again.
