Safety measures and traffic congestion measures

We are working to prevent traffic accidents during the intensive construction period by raising awareness at construction restrictions and traffic jams and implementing continuous regulations.

Preventing rear-end collisions at the end of traffic jams

In order to prevent rear-end collisions at the end of traffic jams, traffic warning information will be provided and warning signs will be placed in front of construction restrictions or at the end of traffic jams in response to traffic jams.

Warning sign car

Implementation of continuous regulations, etc.

Security officers patrol all the time to guide emergency vehicles and troubled vehicles, and to check regulatory materials.

In addition, if construction is restricted in a short section, the number of junctions will increase and cause rear-end collisions. For this reason, even in places where construction is not performed, regulations are continuously implemented for safety.
