Thank you for waiting. From now on, we will start the 120th regular meeting.

[Introduction]

[Miyaike president]

Before I start the interview, I would like to say a few words.
Sasago Tunnel It has been four years since the 2nd of this month since the fall of the ceiling panel, and on the same day, a memorial service was held in Yamanashi Prefecture.
In the memorial service, we would like to extend our deepest sympathies to all those who have died, and deeply apologize to the bereaved families.
We pledged that we will continue to make every effort to further improve safety and enhance functions so that we can keep this accident firmly in mind and never let it happen.
Thank you for your cooperation in covering the day.

[Current status of business (November 2016)]

Please see Document 1.
Regarding operating conditions, toll revenue in November was 55,388 million yen, an increase of 2.3% from the same month of the previous year, and the number of traffic per day was 24,000 units, an increase of 3.1% from the same month of the previous year. ..
In November, toll revenue and the number of vehicles passed increased due to the opening effect of Shin-Tomei Expressway Tomei and the Tomei intensive construction being changed from November last year to September-October this year.

Next, regarding the status of construction, we will explain the new section in a later topic.
Please see the map in Document 1.
Ken-O Road ・ Hachioji West Interchange (IC) Kan-Etsu Expressway The entrance / exit is on December 24th this weekend, again Hokuriku Expressway ・ Kotanijo IC March 25th, 2017 We will inform you that it will be open on the day.
The number of smart ICs under our control is 22 in business and 33 in business.

Next is the status of the service area (SA).
Sales in the SA / Parking Area (PA) in November were ¥ 15,613 million, an increase of 1.7% from the same month of the previous year, and sales of the Food and Beverage / Sales division decreased by 1.5% from the same month of the previous year.
The main reason for this was that last year's three consecutive holidays were from November 21 to 23, but this year it was a stepping stone consecutive holiday, and we were not blessed with days and days, and there were one less holiday compared to last year. Sales in the Food and Beverage Sales Division were 98.5% of the same month of the previous year.
Sales in the gasoline sector increased 9.6% year-on-year, due to the narrowing of the selling price gap compared to last year and the fact that the quantity of diesel fuel supplied exceeded the previous year.

[Chubu-OdanExpwy Rokugo IC to Masuho IC will open in March 2017]

Please see Document 2.
It is expected that the section of Chubu Odan Expressway from Rokugo IC to Masuho IC will be opened in March 2017 as planned.
It is expected that this opening will improve productivity by shortening the time required for Shimizu Port, improve accessibility to surrounding cities such as Kofu City, and support emergency medical activities.
We will inform you about the opening date and time again based on future construction progress.

[Chubu-OdanExpwy Masuho IC will be closed between Futaba JCT day and night]

Please see Document 3.
Prior to the opening of Chubu Odan Expressway Rokugo IC to Masuho IC, which was explained earlier, the relocation work of the toll gate of the Southern Alps Main Line is required. Also, along with the relocation work, we will carry out refreshing work such as improving the pavement in areas where the damage is significant.
For this reason, Chubu Odan Expressway 's Masuho IC to Shirane IC up-and-down lines, including February 4th for a spare day, will be from February 20th (Mon) to March 10th (Fri). ), From Shirane IC to Futaba Junction (JCT) for 13 days, from February 20th (Mon) to March 5th (Sun), 2017 Closed day and night.
We apologize for the inconvenience, and we appreciate your understanding and cooperation.

[Information for "technical training institutes" aimed at improving the safety of Expressway]

Please see Document 4.
Our subsidiary, Nakanihon Highway Engineering Tokyo, opened a "Technology Training Center" in Sagamihara City, Kanagawa Prefecture, in October of this year with the aim of improving human resources and technical capabilities related to safety and inspection of Expressway. ..
In order to provide more practical and effective training, we have installed road structures and facility equipment equivalent to those at the actual site.
For example, in a half-section tunnel facility, you can perform tapping sound inspection of lining concrete, flow measurement training of water spray equipment, disaster prevention training such as fire hydrants and fire detectors.
You can also conduct bridge inspection training using full-scale bridge samples and the removed parts generated in renewal projects (large-scale renewal and repair projects).
Currently, our group has training such as "New Bridge" in Nagoya University for the purpose of improving bridge maintenance technology and "E-MAC" mainly in Kakamigahara City, Gifu Prefecture for the purpose of improving facility maintenance technology. We have facilities, but the establishment of a training facility in Sagamihara City, Kanagawa Prefecture, aimed at improving overall road and facility maintenance technology, has made it possible to enhance training and improve efficiency, I hope that our technical capabilities will improve further.
In addition, even after the opening in October of this year, we have been carrying in the removal materials and other materials that will be generated in the renewal project, and we hope to inform the media-related people around the end of January next year when these training will be further enhanced. I am.
More details will be announced later.

[Development of tunnel inspection technology using high-speed image processing]

Please see Document 5.
As part of our efforts to improve safety, the Group is developing technology aimed at making inspections more sophisticated and efficient.
In this, we will report on the research results that have been aimed at the practical application of the "in-tunnel inspection technology using high-speed image processing" that we have been developing for some time.
Development of inspection technology inside tunnels using image processing cameras is being carried out elsewhere, but the feature of this time is that it is a portable system. Digital image processing technology using a high-speed rotating mirror developed by the University of Tokyo has enabled downsizing.
As you can see in the picture, the camera on the car can be easily removed, so it can be replaced. This keeps costs low without the need for a private car.
Currently, inspections of tunnel structures are carried out once every five years by traffic control, and by close-up visual inspection, tapping, and palpation using an aerial work vehicle.By using this system, The condition of the tunnel can be constantly monitored even during daily patrols, further improving the reliability of inspection.
At the moment, I think it is difficult to completely replace inspection work, but it is expected that it will eventually replace it as improvements are made.
In this research, as described in the attached sheet, we succeeded in detecting cracks without blurring even at 100 km / h. We are currently improving the accuracy of the camera and will be able to detect up to 0.2 mm by the end of this year.
We also believe that the amount of work will be reduced because cracks can be automatically detected in the shot images.
We are currently making final adjustments to the camera and aim to introduce it in 2018.
In the future, we will continue to develop tunnel and bridge inspections that utilize ICT technology, and technology for improving efficiency, in anticipation of changes in the social and economic environment and the social situation in which the working population will decline due to the declining birthrate and aging population. I will.

These are the topics we have prepared today.

[Moderator]

Now, let's receive your questions.

[Reporter]

Regarding the development of inspection technology in the tunnel, it is a bit quick talk, but it is said that it is being developed for introduction in 2018, and while other road managers are raising the issue of inspection sophistication, Is it possible to expand the provision of technology?

[Miyaike president]

I want to think concretely when it is completed.

[Reporter]

The technical training center was opened in October, but is it okay to announce today?

[Miyaike president]

We have already opened it and are operating it, but as I said, we are still bringing in the equipment. We are pleased to announce today, and we will inform everyone in the press in January next year.

[Reporter]

Please tell us how long you have been developing the inspection technology in the tunnel, and how much time can be saved by using this technology.

[Miyaike president]

According to the law, the inspection of the tunnel is to be performed by visual inspection once every five years, and it is basically done manually using a work platform such as an aerial work platform. Currently, we are developing a camera mounted on a vehicle that is constantly patroling while taking images, while continuously observing the deformation of the wall surface and performing image analysis to close the camera once every five years. The aim is to further improve the accuracy of visual inspection. I think that if you constantly monitor the things that change with data, the accuracy of the inspection will be further improved, and even if you perform a close visual inspection once every five years, you can clearly see what is the point. So I think it is very effective.

[Reporter]

You once announced that you would develop the inspection technology in the tunnel once in March 2014, but today you announced that it is now possible.

[Miyaike president]

It is a status report.

[Reporter]

Does it mean that the operation is actually after 2018?

[Miyaike president]

For a while, we will conduct tests in the actual field to improve accuracy, and in 2018 we would like to put it into practical use.

[Reporter]

I think NEXCO WEST is developing something similar, but what is this and what are your relationships?

[Miyaike president]

What we are developing in western Japan is not such a mirror type, but a mechanism that shoots a picture at a stretch while shining bright light and then makes it a picture. In the case of western Japan, the car is also a dedicated vehicle, but our company's one is a very compact and portable system, so it can be reloaded into the car, and I think that the property is slightly different in that it can be inspected while always running. ..
