Five. Requests to customers for safe driving and alleviating traffic congestion
When using Expressway, please check the "Knowledge when using Expressway" [Attachment 4 [PDF: 704KB]] before departure so that all drivers and passengers can drive safely. .
In addition, a little effort on the part of customers will lead to alleviation of traffic congestion. Thank you for your cooperation.
- Watch out for speed drops on In-bound and "sag"
Please help us to recover speed in places where we warn you to slow down, such as In-bound and sag parts! - Do not over tighten the following distance
Please secure enough following distance so as not to step on unnecessary brakes while driving! - Avoid lane changes
Please refrain from changing lanes more than necessary during traffic jams, as it will cause traffic jams to get worse!
NEXCO EAST Group has positioned the period from 2021 to 2025 as "a period to contribute to the achievement of SDGs and transform toward a new future society", and is conducting various initiatives.
We believe that our efforts to predict traffic congestion on Expressway during Golden Week will contribute to SDGs goals 3 and 9 as business activities that lead to the provision of safe road spaces by alleviating traffic congestion.
