  • The speed enforcement camera has been regarded as one of the most important safety countermeasures. Drivers decelerate in front of the speed enforcement camera and gain speed up after passing the camera. So there is a strong need to develop the method how to place the camera to overcome this problem. This study applied the concept of design consistency to the installation of the camera, so speed difference along the road sections should be controlled within the predetermined boundary. Specially, this study also regarded camera as the one of the elements of the road alignments which can change the speed of drivers abruptly, and suggested the way to put this concept into the selection of the placement of the camera.

  • 기존 과속단속카메라의 한계와 더불어 차량의 속도 거동이 더욱 순화될 필요가 제기됨에 따라 국내에서는 2007년 12월 16일 영동고속도로 둔내터널에서 처음 구간과속단속시스템을 도입하였다. 현재 고속국도 6개소를 포함하여 총 8개소에서 구간과속단속시스템을 운영하고 있다. 하지만 해당 시스템의 도입효과가 명확하지 않아 시스템의 효과에 대한 의문도 꾸준히 제기되고 있다. 본 연구에서는 미국 Los Alamos연구에서 개발된 TRANSIMS(TRansportation Analysis and SIMulation System)의 시뮬레이션 결과를 이용해 시스템 적용 전 후의 거시적 교통류 특성을 수집하여 효과에 대하여 분석하였다. 본 연구에서는 구간과속단속시스템의 효과를 분석하기 임의의 네트워크를 제작하여 모의실험을 해 보았다. 네트워크는 총 연장 12km의 직선형 구간으로 제작하였다. 모의실험에 사용되는 링크의 Cell크기는 3m로 설정하여 TRANSIMS의 내정값인 7.5m보다 더욱 상세한 결과가 나오도록 설정하였다. 링크는 편도 3차로로 설정하여 모의실험을 실시하였으며, 구간단속이 미치는 영향을 실제와 유사하게 적용하기위해 모의실험을 하는 링크의 제한속도를 구간단속 실시 전에는 160km/h, 실시 후에는 100km/h로 설정하였다. 구간단속 실시 전 링크의 제한속도를 160km/h로 높게 설정한 것은 실제 통행이 발생하는 속도를 구현하기위해서이며, 차종별 최대 속도를 제한하여 속도분포를 나타내었다. TRANSIMS를 통한 구간과속단속시스템의 효과를 분석하는 모의실험 결과 그림 1의 그래프에서 나타나는 것과 같이 구간단속 전 후에서 속도저감효과가 나타나는 것을 확인 할 수 있었다. 특히, 교통류율이 낮을 때 속도가 높게 나타나던 부분이 구간단속 실시 후 속도가 낮아지는 것을 보아 실제로 교통류율이 낮은 고속국도에서는 높은 효과를 기대할 수 있다고 판단된다. 표 1에서 구간단속 전 후의 주행차량의 속도변화를 살펴보면 과속운행의 비율이 상당히 주는 것을 확인할 수 있다. 이러한 특성 때문에 교통량이 비교적 적은 고속국도에서는 뛰어난 효과를 발휘할 것이라고 예상된다.

  • 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.

  • The increasing interest in the use of automated photographic equipment in Korea enables to detect speed violation and enforce traffic laws. Since 1996, Korean National Police Agency has been promoting a project for installation of Automated Speed Enforcement (ASE) system aiming at reduction of accidents. Recently, point to point speed cameras operate to measure a driver's average speed across length of road and/or the spot speed at individual camera sites along the road length. In this study, we were analyzed to driver's operating characteristics in point to point speed cameras. The point to point speed camera system has link-long influence on drivers and their speeds despite enforcement being visible only at the start and end of enforced road length. Then, mean and 85th percentile speeds were below speed limit along enforced road length by the two camers. Also, Female drivers were driving at low speed than male drivers along the road length.

  • The automatic speed enforcement system is expected to play an important role as intelligent transport system (ITS) or advanced franc management system (ATMS). It must be a reliable system checking the overspeedy vehicles automatically, while savine the police manpower and ensuring a safe traffic flow. In terms of traffic engineering, the automatic speed enforcement system may serve to improve driver's violent behaviors, facilitate the smooth and safe traffic flow and thereby, reduce the traffic accident. This study was aimed at analyzing the accident before and after installation of the automatic speed enforcement systems at the frequency, EPDO(equivalent property damage only) and accident cost, analyzing the effects of the automatic system on the traffic flow and accident. As a result, when we equip the automatic speed enforcement system on the downward slope section or after middle section comparing with whole section. We should consider the location of automatic speed enforcement system.

  • 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.

  • The section speed enforcement system measures the starting instantaneous speed, the The section speed enforcement system measures the starting instantaneous speed, the ending instantaneous speed, and the section average speed, and imposes fines only for the portion that has been speeding the most. However, according to the Road Traffic Act, most of the systems are installed on highways, so existing research has been conducted on highway sections. In this study, it is expected that the installation of section speed enforcement systems on general national roads will be expanded according to the revision of related laws. ITS collection and operation data targeting the section speed enforcement system installed on National Road 3 Seongnam Icheon-ro was used to analyze traffic speed, standard deviation of traffic speed, and reduction in traffic accidents by dividing it into before installation, trial operation period, and after crackdown. As a result of the analysis, the traffic speed, standard deviation, and traffic accidents decreased by 13%, 25%, and 70%, respectively, after installation, confirming that the installation of the section speed enforcement system greatly contributed to the reduction of accidents.

  • As various social problems occur due to increasing traffic accidents, the government has setup and executed strong safety policies. As a result, the number of traffic accidents and the death toll have been decreasing in recent years. However, the setup and execution of the various policies for reducing traffic accidents cost much, so it is necessary to evaluate the cost-effectiveness of each policy. In the present study, enforcement by means of an unmanned over-speed enforcement system, the enforcement effect of which was proven good compared to the cost required for traffic enforcement, is compared with enforcement by policemen. As a result of the comparison, the average speed was 82.66 km/h before the use of unmanned systems and policemen; the average speed with manned enforcement was 70.57 km/h; and the average speed with unmanned systems was 67.85 km/h. The speed limit violation rate was 65% before the use of unmanned systems and policemen; 32% with manned enforcement; and 15% with unmanned systems. Considering the kinds of vehicles, the average speed and violation rate were highest among private cars, then vans, and then trucks.. Considering lanes. The accident rate was estimated based on the above results, and the input cost-to-advantage was estimated. The annual cost-to-advantage was estimated by comparing the above estimated values with the conditions before the unmanned over-speed enforcement system. Subsequently, the enforcement by policemen showed a negative advantage of 76,130,590 won, and the enforcement by the unmanned system showed a positive advantage of 38,577,670 won.
