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.

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.

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.

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.

2016年にNEXCO3社で技術公募をおこなった、逆走対策技術テーマⅠ(道路側での物理的・視覚的対策により逆走車両へ注意喚起をおこなう技術)について、2024年7月24日に開催された「高速道路での逆走対策に関する有識者委員会(第7回)」での対策効果等の報告を踏まえ、各技術の特長や効果が整理された「逆走対策技術カタログ ~物理的・視覚的対策~」(全10技術)を公表いたします。今後、当該カタログを活用しながら高速道路で繰り返し逆走が発生している箇所等へのさらなる現地展開を進めてまいります。
