NEXCO EAST Hokkaido Regional Head Office (Sapporo Atsubetsu Ward), in order to prevent accidents caused by drowsy driving and careless driving in the tunnel (vaguely operation), let you know that we have established the "accent lighting".

E38 Doto Expressway has sections of long continuous tunnels, and serious accidents occur due to drowsiness and absent-minded driving due to the monotonous scenery.

This time, in order to change the monotonous view and prevent involuntary driving, we installed "accent lighting" as a new initiative in a part of the emergency parking zone in the tunnel (installation completed on October 30, 2018). .

NEXCO EAST will continue to make various efforts to ensure safe driving on Expressway.

(1) Installation location

It was installed in the section including before and after Hobetsu TN where a serious accident occurred in January 2018.

LED lighting fixtures illuminate the wall surface inside the tunnel in spots such as blue and green to accent the driving landscape. (Hobetsu TN / Tannenai TN ... blue, Chowa TN / Shimukappu TN ... green)
