Zero slip accidents in tunnels: Automatic spreading device for freeze prevention solution, Tokebo.

Driving through winter tunnels is full of dangers! Dramatically improve road conditions with the installation of Tokebo and achieve zero accidents!

Be cautious of slip accidents when driving through tunnels in winter. During the winter months, tunnels can be dangerous due to hidden icy patches in the darkness and sudden changes in road conditions at the entrances and exits. In the Nagate Tunnel on the main local road Yonezawa-Takahata in Yamagata Prefecture, 14 traffic accidents occurred within two years after its opening in 2013. Of these, 11 were caused by slips due to road surface freezing. In response, in 2015, a freezing prevention solution automatic spraying device called "Tokebo" was installed. This dramatically improved road conditions and achieved zero accidents caused by freezing slips. **Features of the freezing prevention solution automatic spraying device "Tokebo":** - Compact one-box type weighing 250 kg - Can be moved and installed as needed at necessary times and locations - Operates on solar panels and batteries, eliminating the need for commercial power - Fully automatic operation using snowfall and temperature sensors and a timer - Compatible with various freezing prevention solutions It is also active at traffic hubs across the country, not just in tunnels!
