Measures to prevent reverse running

Various countermeasures are taken to prevent reverse running

Various measures are being taken on Expressway to prevent reverse running.
For example, an arrow is displayed on the surface of a Expressway, etc., to indicate the direction of travel of the vehicle, thereby preventing reverse running.

Show arrow on road surface

When merging from the service area or toll gate to the Expressway main line, a rubber pole is installed at the merging point so that you do not make a mistake and go in the wrong direction.

Prevent reverse running with rubber pole

Also, to prevent accidentally entering the oncoming lane after passing through the toll booth, the toll booth plaza section * We are implementing deadline measures.
(Signages and road markings are installed at tollgates where the deadline is difficult to manage.)

* From the toll booth to the confluence section.

Deadline measures and installation of warning signs

There are also signs that call attention to vehicles that are likely to reverse. Notifying the driver who is going in the opposite direction, "I will not go here" will prevent reverse running.
In addition, there is a display panel that emits light only when a reverse vehicle is detected and displays a warning such as "Reverse" to remind you that you are traveling in the reverse direction.
