A "traffic barrier" is a device installed in locations where traffic regulation is necessary during disasters, allowing for traffic blockage as needed. Our company has examples such as the installation of the "DG type" in Okinawa Prefecture (Southern East Road), the "SG-3 type" at the Hakonegasaki Underpass (Mizuho Town, Nishitama District), and the "HN-1 and 2 types" in Takahashi City, Okayama Prefecture (mountainous area). By physically closing off areas, we can also expect to prevent secondary disasters caused by mistakenly entering due to overlooking display boards and other warnings. 【Examples (excerpt)】 ■ DG type - Okinawa Prefecture (Southern East Road) - Tomei Expressway (Yui PA) - Osaka City (Namikihara Ohashi) *For more details, please refer to the PDF materials or feel free to contact us.

In the case of bridges, following the damage caused by Typhoon No. 21 in 2018, pre-traffic regulations have been implemented in areas where certain wind speeds are anticipated, with the aim of preventing the expansion of damage and avoiding traffic confusion caused by sudden regulations. This has been discussed and introduced in various locations. Our company has examples such as the installation of the "SG-1 type" in Amagasaki City, Hyogo Prefecture (existing bridge) and the installation of the "SG-3 type" in Kawasaki City, Kanagawa Prefecture (new bridge). We have introduced these examples with photographs, and we hope they will be helpful for your considerations regarding implementation. 【Examples (excerpt)】 ■ Amagasaki City, Hyogo Prefecture (existing bridge) - SG-1 type (one unit for each lane on one side, fully closed with double doors) - A tarpaulin sign that wraps and stores is deployed when barriers are in place. ■ Kawasaki City, Kanagawa Prefecture (new bridge) - SG-3 type (only one lane on each side for both directions) - Curved pillars are used to minimize interference with the sidewalk area. *For more details, please refer to the PDF materials or feel free to contact us.
