Traffic police officers are faced with many dangerous accidents due to outside duties on roads. Yet, researches on traffic officers' uniforms have mainly been focused on design aspects rather than functional aspects. This study therefore aims to figure out traffic officers' perceived needs for their uniforms and to offer some basic guidelines in manufacturing versatile safety vests for wearers. The study used a documentary survey replied by 236 traffic officers. The results of the study are as follows: 1. There are 10 different types of vests currently used by traffic officers. Vests are employed for purposes such as carrying police equipments, enabling officers to be noticeable in dark, protecting the body, etc. 2. Officers wear these vests which were officially designated by law. Among them, fluorescence versatile safety vests were most frequently worn by officers. 3. Officers who wore ready-made vests of which size was already determined, tended to perceive that the vests were relatively larger than their own size. 4. In terms of the functions of the vests, officers expressed needs for the improvement of the LED and retro-reflection tape along with the addition of thermal function to existing vests. The improvement of the form and functions of versatile safety vests which reflect needs of the users will boost the dignity and the sense of duty of the traffic police officers.

최근 교통환경 개선으로 교통안전이 획기적으로 향상되고 있으나, 여전히 운전태도에는 변화가 없어 많은 사고로 이어지고 있다. 이 연구에서는 교통과태료 및 범칙금제도가 갖고 있는 문제점을 지적하고, 국민의식조사를 통해 적정한 과태료 및 범칙금수준에 대해 탐구하고자 한다. 이를 위해 전국 15개 광역시도의 20세 이상 성인 운전자 905명을 대상으로 설문조사를 실시하였다. 분석결과는 다음과 같다. (1) 우리나라 교통환경은 전반적으로 불안전하며, 난폭운전, 과속운전, 음주운전 등 운전자의 교통법규 미준수가 교통사고의 중요한 원인으로 인식하고 있다. (2) 전체 응답자의 61.6%가 연 1회 이상 과속운전을 경험하지만, 최근 3년간 단속을 경험한 운전자는 15.2%에 불과하였다. (3) 교통과태료의 수준에 대한 저항감은 과거보다 낮아졌고, 보다 많은 정보를 제공했을 때 긍정적인 답변을 제시하였다. (4) 벌점을 회피하기 위한 과태료납부의 도덕적 해이현상을 억제하기 위해 범칙금보다 과태료가 최소 5~7만원이상의 차이가 있어야 한다. (5) 교통범칙금은 위반자의 소득수준에 따른 차등부과 형식보다 누진처벌제도를 도입하는 것에 대한 저항이 적었다. (6) 현 도로교통법 위반행위별 부과 과태료는 재정비가 필요하다. 결론적으로 이 연구에서는 현행 도로교통법의 과태료 및 범칙금 제도개선을 위한 정책적 제언을 다음과 같이 제시한다. (1) 제도개선에 대한 충분한 이해와 공감대 형성이 필수적이다. (2) 차주에 대한 벌점부과 등 금전적 제재보다 행정적 제재를 고려해야 한다. (3) 누진처벌에 대한 제도도입을 고려해야한다. (4) 현 도로교통법 위반행위와 과태료 및 범칙금 수준에 대한 전반적 재정리가 있어야 한다.

As invigoration plan of the marine tourism, Busan City has the plan to operate the cruise ship inside of the harbor, but the area has narrow water way with heavy traffic. As a result it is requested to evaluate the safety for the preparation of actual navigation. In this study, the Ship Handling Simulation (SHS) Assessment was conducted, which is regulated by the Maritime Traffic Safety Audit Scheme (MTSAS) in compliance with the Marine Safety Law and the Maritime Traffic Risk Assessment System based on the Electronic Chart Display and Information System (ECDIS). The proximity assessment, control assessment and subjective assessment were implemented, which is enacted by the Marine Safety Law by using the SHS. In the case of proximity assessment, the probability of trespass was not analyzed. As the control assessment, the swept path was measured at 11.7 m and 11.5 m for port entry and port departure respectively, which exceeded the width of the model vessel, 10.4 m over; it was considered as a marginal factor. As a result of the subjective evaluation of the navigator, there would be no difficulty on ship maneuvering by paying particular attention to the mooring vessel nearby the Busan Bridge and Yeongdo Bridge as well as the coming vessel from the invisible sea area when the vessel is entering and departing the port. The Marine Traffic Risk Assessment System analyzed as [Cautious] level until the vessel passed the Busan bridge and the curved area at 5 kts and it became to [Dangerous] level from where it left 75 m to the Busan Bridge. When the vessel passed the Busan Bridge and the curved area at 10 kts and entered the narrow area, it indicated the [Dangerous] level and became to [Very dangerous] level from where it left 410 m to the Busan bridge. In conclusion, the vessel should maintain at the speed of 5 kts to reduce the risk when it passes this area.

The speed of vehicles has remained a significant factor that influences the severity of accidents and traffic accident rate in many parts of the world including South Korea. This behavior where drivers drive at speeds which exceed a posted safe threshold is known as 'speeding'. Over the past twenty years, the Korean National Police Agency (NPA) has become aware of an increased frequency of drivers who are speeding. Therefore, fixed-type ASE systems [1] have been installed on hazardous road sections of many highways. These system monitor vehicle speeds using a camera. However, the use of ASE systems has changed the behavior of the drivers. Specifically, drivers reduce speed or avoid the route where the cameras are mounted. It is not practical to install cameras at every possible location. Therefore, it is challenging to thoroughly explore the location where speeding occurs. In view of these problems, the author of this paper designed and implemented a prototype visualization system in which point and color are used to show vehicle location and associated over-speed information. All of this information was used to create a comprehensive visualization application to show information about vehicle driving. In this paper, we present an approach detecting vehicles moving at speeds which exceed a threshold and visualizing the points those violations occur on a map. This was done using vehicle trajectory data collected in Daegu city. We propose steps for exploring the data collected from those sensors. The resulting mapping has two layers. The first layer contains the dynamic vehicle trajectory data. The second underlying layer contains the static road networks. This allows comparing the speed of vehicles on roads with the known maximum safe speed of those roads, and presents the results with a visualization tool. We also compared data about people who drive over threshold safe speeds on each road on days and weekends based on vehicle trajectories. Finally, our study suggests improved times and locations where law enforcement should use monitoring with speed cameras, and where they should be stricter with traffic law enforcement. We learned that people will drive over the speed limit at midnight more than 1.9 times as often when compared with rush hour traffic at 8 o'clock in the morning, and 4.5 times as often when compared with traffic at 7 o'clock in the evening. Our study can benefit the government by helping them select better locations for installation of speed cameras. This would ultimately reduce police labor in traffic speed enforcement, and also has the potential to improve traffic safety in Daegu city.

Using network betweenness centrality we attempt to analyze the characteristics of Seoul metropolitan subway lines. Betweenness centrality highlights the importance of a node as a transfer point between any pairs of nodes. This 'transfer' characteristic is obviously of paramount importance in transit systems. For betweenness centrality, both traditional betweenness centrality measure and weighted betweenness centrality measure which uses monthly passenger flow amount between two stations are used. By comparing traditional and weighted betweenness centrality measures of lines characteristics of passenger flow can be identified. We also investigated factors which affect betweenness centrality. It is the number of passenger who get on or get off that significantly affects betweenness centrality measures. Through correlation analysis of the number of passenger and betweenness centrality, it is found out that Seoul metropolitan subway system is well designed in terms of regional distribution of population. Four measures are proposed which represent the passenger flow characteristics. It is shown they do not follow Power-law distribution, which means passenger flow is relatively evenly distributed among stations. It has been shown that the passenger flow characteristics of subway networks in other foreign cities such as Beijing, Boston and San Franciso do follow power-law distribution, that is, pretty much biased passenger flow traffic characteristics. In this study we have also tried to answer why passenger traffic flow of Seoul metropolitan subway network is more homogeneous compared to that of Beijing.

In roadside workplaces, more attention should be paid to the safety of workers. The roadside workers underestimate the effect of the brightness of their clothes and judge that drivers will recognize them easily, and the drivers misjudge that the roadside workers are far away and that the vehicle can be stopped in sufficient time. Therefore, customized safety education reflecting this and wearing work clothes with certified visibility functions are required. In Korea, it is not compulsory for roadside workers and vehicle guide attendants to wear work clothes with a visibility function. In this study, the distance ahead perceived by drivers was measured using manikins wearing certified and non-certified reflective safety vests. The perception distance of the non-certified reflective safety vest was 1.4 times longer than that of the certified reflective safety vest, thus confirming the importance of wearing a certified reflective safety vest. To prevent roadside workers from suffering traffic accidents, we propose the enactment of a law that makes it mandatory for them to wear high-visibility safety clothing. Specifically, Article 32 of the Enforcement Regulation of the Road Traffic Act should include high-visibility safety clothing in life protection equipment, and additionally, to prevent secondary accidents, we propose the enactment of a law requiring the installation and wearing of certified reflective safety vests in vehicles.

PURPOSES: This study aims to suggest a proper left-turn treatment method for the bicycle traffic flow at four-legged intersections. METHODS: Four types of crossing methods are proposed and analyzed : (1) indirect left turn, (2) direct left turn, (3) direct left turn on a Bike Box, and (4) direct left turn on bike left turn lane. The VISSIM simulation tests were conducted based on forty-eight operation scenarios prepared by varying vehicle and bicycle traffic volumes. RESULTS : The results from the four-legged signalized intersections suggest that (1) the indirect left turn is appropriate when vehicle demand is high, (2) the direct left turn is efficient on most traffic situation but the safety is a concern, (3) the direct left turn on a Bike Box is appropriate when bicycle demand is high while vehicle demand is not, and (4) the direct left turn on a bike left turn lane is appropriate when both vehicle and bicycle demand are low. CONCLUSIONS : The direct left turn of bicycle provides more efficiency than the indirect left turn at the four-legged intersections but to apply the methods and to study more, advanced evaluation methods, related law, and insurance programs are needed.
