본 논문에서는 통학버스에서의 안전사고에 관련된 여러 사례 중 출입문의 끼임을 방지하기 위하여 통학버스에 영상장치와 전원센서를 부착, 사각지대를 없애고 운전자에게 경보음으로 사고를 미연에 방지하고자 하는 시스템을 제안하고자 한다. 출입문의 배경영상을 적용적으로 수집하고 실시간으로 수집되는 영상과 배경영상을 차 연산 하여 문의 끼임을 인식한다. 실험결과 문에 대해서 끼임이 검출되는 것을 확인할 수 있었다.

As the use of children's school buses increases, accidents caused by the negligence of school bus drivers and ride carers have also increased significantly. To prevent such accidents, the government is coming up with various policies. We propose an accident prevention and safety management system for children's school buses. Through this system, bus drivers can easily check whether each child is seated and whether the seat belt is used, so it is possible to quickly respond to children's conditions while driving. With the ability to recognize faces by analyzing camera images, children can use a seat belt that is automatically adjusted to their height. It is therefore possible to prevent secondary injuries that may occur in the event of a traffic accident. In addition, a sleeping child-check system is provided to confirm that all children get off the bus, and a text service is provided to inform parents of their children's locations in real time. Based on Raspberry Pi, the system is implemented with cameras, pressure sensors, motors, Bluetooth modules, and so on. This proposed system was attached to a bus model to confirm that the series of functions work correctly.

The incident during commuting to school happened frequently in these days, such that the government announced the student commuting safety policy for addressing to implement the safety management system of the unsafer school commuting zone. In this paper, a commuting tracking system is proposed that notifies the location of vehicles and the boarding status of student using BLE beacon and smart phone GPS function. The commuting tracking system that gets the data from the system server of driver's smart phone GPS location and UUID of the beacon which had provided students has configured to provide notifications to parents and related administrators. It provides real-time information about whether a student boarding, boarding times and bus locations for parents and administrators. It verifies the disembarking time for each student and also provides to driver to secure if any student tries to board the wrong school bus and if any students is left behind in the bus.

When a children's school bus stops on the road, the operator enables an amber flashing light (indicating stopping or slowing) or a red flashing light (indicating that children are getting on and off). Drivers of vehicles passing by the stopped school bus, as well as vehicles in adjacent lanes to the school bus must stop temporarily. However, many drivers are not aware of the laws and do not comply with them, so children are exposed to an increased risk of being hit, especially at night as the color recognition of the vehicle is significantly lower than during the day. In our experiments, messages and shapes using light were projected to the front and rear of a parked school bus, in addition to its red lights flashing.

In recent years, the population of children has been declining in Korea. Moreover, the phenomenon of elementary school closures is on the rise, particularly in non-urban and some new city areas, highlighting the need for school buses for children. Despite the mandatory safety features in place, accidents involving school buses for children are on the rise, underscoring the need for improvement in the safety of these vehicles. While various studies have been conducted to enhance the safety of children during their school commute, there has been a notable gap in research analyzing the school commuting environment concerning the vehicle safety of these buses. Hence, this study aims to develop a set of service evaluation criteria for school bus routes, considering vehicle safety through the Analytic Hierarchy Process (AHP). By conducting a survey to gather information on the current status of school buses for children and through questionnaires targeting stakeholders in the school bus sector, the study analyzed requirements and operating conditions. These results were used to select evaluation criteria and structure the hierarchy based on the external and internal aspects of school bus services. Through AHP surveys conducted based on the designed criteria, experts identified safety as the most crucial aspect, with a specific emphasis on Vehicle Safety. Using these developed service evaluation criteria, the study plans to identify service-vulnerable routes through a real route analysis and recommend improvements, with the ultimate goal of creating a safe and convenient school commuting environment for children.

As the use of school buses becomes more common, related laws are being enacted, such as making it mandatory for children to check school bus dropouts due to frequent accidents caused by the negligence of school bus drivers and their guardians. In this paper, we propose a safe school bus system that links efficient radio-frequency identification (RFID) and mobile APP in terms of energy utilization and cost. The school bus system uses RFID cards to check information on children boarding the school bus, and real-time SMS transmission allows parents to safely send their children to and from school. Instructors on the school bus can check their children's disembarkation information once more through APP, preventing various accidents that may occur to children left on the bus. Due to the automation of the school bus operation log, daycare center teachers can not only check the information on getting on and off, but also manage the information on the attendance and discharge of the students.

본 논문에서는 유아보호를 위한 차량용 스마트 알림 시스템을 설치해야 한다는 것을 제안한다. 여름철 유아들이 차량에 갇혀 숨지는 안타까운 사건이 빈번히 일어났다. 현행 도로교통법에서는 어린이 통학버스를 운전하는 사람은 운행을 마친 후 어린이나 영유아가 모두 하차했는지를 확인 하도록 규정하고 있고 통학차량에 일정 인원 이상의 유아들이 탑승하면 통솔인원교사가 등.하교 길에 동행하도록 의무화 되어 있다. 그럼에도 불구하고 여전히 통학차량에 유아들이 방치되어 사망하는 사건사고가 일어나고 있다. 외국에는 챠량 내부의 모든 버튼을 인식 하여야 차량의 시동이 멈추게 된다. 하지만 유아를 차량에 두고 나오는 사고가 났다. 차량용 스마트 알림 시스템은 기존 버스 내부에 RF카드를 인식하면 유아의 학부모에게 문자가 전송되게 되며 차량 어디에 위치하였는지 표시가 되게 된다. 이로인해 차량에 유아를 두고 내리는 일이 없게 되며 유아가 차량을 언제 탑승하였는지 확인할 수 있게 된다.

Accidents of commuting vehicles for kindergarteners and nursery school students continue to occur despite various safety policies from the government. In order to minimize such accidents, it is necessary to use both the vehicle-mounted safety commutation management software which can be easily operated by the driver, and the mobile app to manage the safe schooling of the children that can inform such information to parents timely. In this paper, we describe the design and implementation of the safety management software architecture.

Since the mid 1990s, policies have been actively promoted to improve safety and pedestrian environment around the school such as the improvement of School zone. However, the prevention of accidents was not effective because it did not extend to the school road where the main transportation route for children's commuting takes place. In addition, due to the rapid increase of automobiles, trunk road traffic in the peak time bypasses the back roads, which threatens children's safety and the environment by invading the school area, which is the main living space of children. In this study, the characteristics of domestic children's traffic accidents were investigated and the problems were analyzed by conducting a field survey on Yeouido Secondary School in Seoul and Unjung Elementary School in Gyeonggi Province. In addition, Variable speed limit signs and Beacons were installed in the pedestrian road of comunity including School zone, and the effects of facilities on the speed of vehicles were analyzed. As a result of the analysis, the Variable speed limit sign showed a deceleration effect of about 8.3km/h, and the Beacon showed a phenomenon in which the traveling speed of 0.8km/h increased only slightly. In addition, the traffic violation rate of passenger cars, buses, and lorries decreased by about 3% as a result of investigating the number of traffic violation vehicles before and after installation.
