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.
Based on the report presented at the 9th meeting of the Expert Committee on Countermeasures Against Wrong-Way Driving on Expressways, held on September 9, 2026, regarding the technology theme II (technology to detect wrong-way driving on the Expressway and collect information on it), for which the three NEXCO companies solicited technical proposals in 2016, we are publishing the "Wrong-Way Driving Countermeasures Technology Catalog - Wrong-Way Driving Information Collection Technology" (2 technologies in total), which summarizes the features and effects of each technology.
- No. 13 Reverse driving detection using microwave sensors
- No. 14 Wrong-way driving detection using image analysis technology utilizing a 3D stereo camera
In 2016, NEXCO 3 companies publicly solicited technology for Wrong-Way Driving Countermeasures Technology Theme I (technology that alerts wrong-way driving vehicles by using physical and visual measures on the road side), and based on the report on the effectiveness of the countermeasures at the "7th Expert Committee on Wrong-Way Driving Countermeasures on Expressway" held on July 24, 2024, we will publish the "Wrong-Way Driving Countermeasures Technology Catalog - Physical and Visual Measures" (10 technologies in total), which summarizes the features and effects of each technology. Going forward, we will use this catalog to further promote on-site deployment in areas where Expressway.

<Check the direction of travel! 〉
Check for signs and signs indicating that you must not proceed, and arrows that indicate the direction of travel, and proceed in the correct direction.
Rubber poles are installed at the junction with the main line to prevent turning.
