Traffic violations such as moving while the traffic lights are red have come from a simple omission to a premeditated act. The traffic control center cannot timely monitor all the cameras installed on the roads to trace and pursue those traffic violators. Modern vehicles are equipped and controlled by several sensors in order to support monitoring and reporting those kind of behaviors which some time end up in severe causalities. However, such applications within the vehicle environment need to provide security guaranties. In this paper, we address the limitation of previous work and present a secure and privacy preserving protocol for traffic violation reporting system in vehicular cloud environment which enables the vehicles to report the traffic violators, thus the roadside clouds collect those information which can be used as evidence to pursue the traffic violators. Particularly, we provide the unlinkability security property within the proposed protocol which also offers lightweight computational overhead compared to previous protocol. We consider the concept of conditional privacy preserving authentication without pairing operations to provide security and privacy for the reporting vehicles.

고화질 블랙박스의 확산과 '스마트 국민제보', '안전신문고' 등 모바일 애플리케이션의 도입에 따른 영향으로 교통법규 위반 공익신고가 급증하였으며, 이로 인해 이를 처리할 담당 경찰 인력은 부족한 상황이 되었다. 본 논문에서는 교통법규 위반 공익신고 영상 중, 가장 많은 비중을 차지하는 차선위반에 대해 딥러닝 알고리즘을 활용하여 자동 검출할 수 있는 시스템의 개발내용에 관해 기술한다. 본 연구에서는 YOLO 모델과 Lanenet 모델을 사용하여 차량과 실선 객체를 인식하고 deep sort 알고리즘을 사용하여 객체를 개별로 추적하는 방법, 그리고 차량 객체의 바운딩 박스와 실선 객체의 범위가 겹치는 부분을 인식하여 진로변경 위반을 검출하는 방법을 제안한다. 본 시스템을 통해 신고된 영상에 대해 교통법규 위반 여부를 자동 분석해줌으로써 담당 경찰 인력 부족난을 해소할 수 있을 것으로 기대한다.

본 논문에서는 교통정보의 자동 전송시스템에 대한 연구결과를 제시한다. 여기서는 구급차나 소방차와 같은 긴급차량의 진로를 방해하는 것을 교통이벤트로 정의한다. 차량 내부에 설치된 블랙박스에 기록되는 동영상으로부터 교통이벤트 발생이 판정되는 경우 해당 정보를 증거영상과 함께 전자우편을 통하여 자동적으로 관제선터에 전송하는 시스템을 구현하였다. 이를 위하여, 전방에서 주행하는 차량의 번호판으로부터 문자와 숫자를 인식하는 알고리즘, 교통이벤트 발생 판정알고리즘을 실현하였다. 또한, 신고를 위하여 텍스트와 영상 파일을 전자우편과 파일전송프로토콜을 통하여 자동 전송하는 기능도 추가하였다. 따라서 교통이벤트를 확장하여 제시된 시스템에 적용하면 다양한 교통법규 위반 사항에 대한 편리한 신고체계를 수립할 수 있으므로 교통법규 위반 사례를 크게 줄일 수 있을 것으로 판단된다.

Civil complaints and lawsuits filed in the process of providing emergency medical service include fall accident on the way of carrying the patient, transfer consent, refusal and rejection of rescue request, range and behavior restriction of emergency medical technicians, false registry of logbook, neglect of duty and emergency patient, and violation of traffic laws on the way of dispatch to the scene of accident. This study suggested the measures by cases as follows. 1. The accidents on the way of carrying a patient could be divided into fall of patient and fall by paramedic's mistake. In the former case, damages caused by the ambulance's shaking must be notified to the patient and guardian and recommended to fasten seat belt, in the latter case, the plan of patient's posture, route of transport, rescue and equipments should be comfirmed before fixing the patient. 2. Transfer consent must be made as implied when the patient is unconscious under delusion and was not able to consent physically, and paramedic must take an action by his judgment and record details of services on logbook. 3. When a patient refused to transfer, get 'confirmation of transfer refusal' and inform him of refusal. Paramedic should receive the signature. In addition, in case of refusal, transfer request should be made after hearing doctor's opinion and it should be notified to transfer request and superintendent of fire station after making 'confirmation of transfer refusal'. 4. Emergency medical technicians should perform their duties within the range of services prescribed by Article 41 of Law of Emergency Medical Service and Article 33 of Its Enforcement Regulations and shall not make announcement of death. In case of reporting the death to guardian, it is desirable to use record data like ECG results. 5. The best way to have protection from legal problems is making and keeping the exact records of accident and patient. Paramedic should not mention his subjective opinion about the accident-related matter. He must record correctly and keep the original medical records. 6. As emergency medical technicians are responsible for taking care of emergency patients, they must contact a briefing room when they meet a difficult situation suddenly due to vehicle stop or treatment of other patients and then must have support from neighboring hospital and other safety centers. 7. Since the ambulance operator is responsible for safety and careful driving of ambulance, he must be careful when he violates traffic regulations unavoidably. The operator should drive slowly below 10km/h at an intersection and pass it after getting way from general vehicles driving from all directions.
