Today, there is a school zone around the school that is a children's protection zone to protect children. Such a school zone is a system for preventing traffic accidents by securing a safe school space for students by designating a main school road within a radius of 300m from the main entrance of elementary school and kindergarten as a protected area and installing traffic safety facilities and road accessories.

School Zone was introduced by the Road Traffic Act in 1995, and in 1995 the 'Rules for the Designation and Management of Child Protection Areas' were established. According to the Road Traffic Act, the mayor, when deemed necessary for the protection of children from the risk of traffic accidents, designates certain sections of the roads around kindergartens and elementary schools as child protection zones, can do. In addition, kindergarten or elementary school presidents can recommend the preschool superintendent or superintendent to designate a protected area, and the superintendent or superintendent can apply for the designation of a protected area to the local police director or local police director.

If it is designated as a protected area, roadside fixtures such as signaling devices and safety signs can be installed, and roadside parking lots can not be installed on the roads directly connected to the main entrance such as elementary schools designated as protected areas. In addition, students can prohibit or restrict the passage of cars during the school day and time in the protected area, prohibit stopping or parking of cars, and limit the speed of operation to within 30 km.

Since 2006, the total number of traffic fatalities has been steadily decreasing, while the number of child deaths in the school zone has been steadily increasing.

The school zone designation rate has been rising from the half of 2006 (49.1%) to 83.0% in 2010 due to the government's aggressive child safety measures project. In addition, a total of 50,472 people were injured and died in five years, but the first grade students in elementary school were the most vulnerable, and 16,500 people were sacrificed.

Especially, on the roads frequently used by children lacking attention and judgment, such as school zone crossings in front of the school, parents or teachers at school can safely cross the crosswalks by using flags. However, There is no one who protects the children crossing the crosswalk because the school hours are not the same, and there are many traffic accidents because the driver's attention is low.

In order to solve such a problem, in recent years, there is a case where the speed of the vehicle is measured at the entrance to the school zone and the measured speed is provided as a number or image so that the driver can check the speed. However, .

In addition, when a pedestrian wishes to cross a pedestrian crossing, a high-speed vehicle frequently collides with pedestrians immediately after the pedestrian signal lamp is turned on because the pedestrian violates the signal or can not stop inadvertently. Particularly, kindergarten or elementary school students do not look around as soon as the pedestrian traffic light turns on, but they jump into the crosswalk only in front of them.

Conventionally, when a signal of a vehicle signal lamp or a pedestrian signal is changed, an orange signal is turned on or a green signal is flickered to give a driver or a pedestrian attention. However, when the signal is too short, There were many.

In other words, the driver checks the green traffic light while driving, and when the signal suddenly changes in the vicinity of the traffic light, the driver can not stop in front of the traffic light because of the speed of the vehicle. Therefore, .

In addition, a pedestrian can check the green signal of a pedestrian traffic light, cross a road, and then a green signal blinks, and some people jump, but some people walk on a good bell. At this time, if the signal is changed while crossing the crosswalk, it is often the case that the person crossing the road does not see the person crossing the road and hits the starting vehicle or the vehicle traveling at high speed. Especially, in the case of elderly people or children who can not detect the change of the signal quickly or the gait is not fast, the frequency of the traffic accident is high in the crosswalk.
