Efforts in the 3-Year Plan for Improving Safety

NEXCO CENTRAL Jurisdiction Expressway, where about 1.87 million vehicles come and go per day The road conditions change every moment. For example, the number of broken cars is about 100 / day, and the number of fallen objects is about 200 / day. In this way, the Road Control Center is at the center of constantly monitoring the ever-changing Expressway situation, communicating information to customers, and issuing instructions and requests to related organizations.

Two functions to move the road control center. Road control and facility control
NEXCO CENTRAL 's Road Control Center monitors the Expressway network in the central part of Japan.The Road Control Center monitors and controls the road conditions, and monitors and controls tunnels, information boards, and other essential facilities for road safety. Facility control is divided into two. All information related to Expressway including CCTV camera images, radio reports from the traffic management corps, and information from customers using the # 9910 road emergency dial, is once collected at the Road Traffic Control Center. For example, when a report of a falling object is received, information on "Caution for falling object" is displayed on an information board, and at the same time, the traffic management corps is instructed to collect it. In addition, if an abnormality occurs in the tunnel, facility control notifies the danger through information boards inside and outside the tunnel, and activates tunnel emergency equipment as necessary.
It is difficult to predict when, where, and what will happen on a Expressway where cars are constantly traveling.To ensure that customers always use the Expressway safely, safely and comfortably, 24 hours a day, 365 days a year It's important to keep watching without interruption.

Combines human eyes and IT to quickly and accurately understand road conditions

Reports from customers helping to understand road conditions
Accidents, broken cars and falling objects occur in various places. Reports from customers are particularly helpful in understanding them, and the trend has become particularly noticeable with the spread of mobile phones. Also, it is very important to receive information from emergency telephones installed every 1 km on the main line (every 200 m in the tunnel). If you pick up the emergency telephone handset, it will automatically connect to the road control center. If you see any abnormalities on Expressway, call 110, emergency call or road emergency dial (# 9910) and tell the person in charge of the situation such as whether there is any injured person Thank you for your cooperation.

  • Emergency telephones are also set up in tunnels, interchanges, and SA and PA.

Traffic counter that automatically detects traffic volume
Traffic counters are installed at various locations on Expressway to inform customers of accurate traffic information. The most suitable method is adopted depending on the location, such as a loop coil type that uses a coil embedded in the road to determine the traffic situation of the vehicle, an image processing method using a CCTV camera, and an ultrasonic method that measures traffic congestion using ultrasonic pulses. The measured traffic data is sent to the Traffic Control Center.

  • In the loop coil method, current is passed through a coil (magnetic sensor) embedded in the road, and the speed is measured by the change in magnetism caused by passing vehicles.

Rain, snow, wind, temperature, fog. Meteorological observation equipment that can perform four roles with one unit
Weather conditions have a significant effect on customer driving. For example, when it rains or snows, it alerts you to slips, when the wind blows it alerts you to rollover, and when fog occurs, it turns on and slows down the lights. For this purpose, weather information measured by weather observation equipment is sent to the road control center in real time. In addition, in order to grasp such information pinpointly, meteorological observation equipment is installed at various places on the Expressway.
Furthermore, earthquake measurement is also very important in the volcanic islands of Japan. Seismometers are also installed at major tollgates on the Expressway, and in the event of shaking, the shaking and scale are measured and sent to the Road Traffic Control Center to take measures such as closing the road.

  • The meteorological observation equipment collects various weather information required for customers traveling on Expressway.

-Calm "judgment" and quick and accurate "initial instruction" are necessary-

Our mission is to provide customers with a safe, secure and comfortable Expressway environment. In the unlikely event of an accident, a broken car, a falling object, or a natural disaster, you must make sure that the safety of the site and the people concerned is the highest priority, but that the traffic is not interrupted as much as possible. What is important is calm "judgment" and quick and accurate "initial response".

-Putting the highest priority on the safety of the workplace and parties, and taking the best measures that do not stop-

For example, a car has stopped in the lane Expressway due to an accident or breakdown. First of all, let other customers know that the accident has occurred. Next, we will enforce traffic regulations and, in some cases, close roads, but their impact is not small. During the Great East Japan Earthquake, Hokuriku Expressway has been designated as an emergency support route to Tohoku. That is why assuming that the highest priority is to ensure customer safety and prevent secondary damage, we need "judgment" and "first move instructions" to somehow avoid traffic closures and traffic restrictions. If an accident or a broken car is blocking the road, first consider whether you can move the car so that it can pass on one lane. In the unlikely event that a road should be closed, we will try to minimize the amount of time you need to stop on the road, such as requesting a tow truck to move the accident vehicle.
In the case of Expressway in the Hokuriku region, where I am in charge, about 70% of the annual accidents and breakdowns are concentrated during the winter months from November to April, and more than 40 cases occur overnight. It can be. In such a case, the radio and road emergency dial from the traffic management team keep ringing, and it is difficult to take a break or eat. Nevertheless, in order to maintain the safety and smooth traffic of the parties, it is necessary to make quick and accurate decisions and respond.

-Sharing experiences and information to improve judgment and accuracy and speed of initial movement-

In this way, "judgment" and "initial response" are very important in the Road Traffic Control Center. To that end, we can greatly improve accuracy and speed by sharing experiences and examples between each person in charge and each Regional Head Office, as well as refining the basic manual. For example, when an accident is reported, a traffic management team is dispatched to the site as soon as possible while checking the collected information.However, before the traffic management team arrives, their experiences and shared cases are shared. We will simulate the on-site response with reference. By doing so, you can make more accurate and faster decisions and instructions.
Therefore, we have a mechanism to share examples and know-how, such as holding an exchange meeting where the general commander gathers once a month, and taking over the details of the event that occurred on the day and the road conditions when the day shift and night shift are changed. Has been established. By actively promoting these initiatives, we will continue our efforts to make judgments and response methods more accurate.

Get the information and response you need, where you need it, as soon as possible

It is no exaggeration to say that initial response is the most important role for a road control center. For example, promptly providing information on a failed car can alert a traveling vehicle to prevent a secondary accident. The Road Traffic Control Center promptly provides information and gives instructions to the site based on the collected information.

Information is displayed instantly where needed
The Road Traffic Control Center strives to provide accurate and accurate information on the various information collected. For example, in the event of an accident or traffic congestion, we will quickly determine the content and location of the information to be provided, and perform input operations quickly and accurately to provide the information.

What are the features of the Kanazawa Regional Head Office Road Traffic Control Center?

-Large display for improved processing capacity, circular layout for smooth communication-

The Kanazawa Regional Head Office Road Traffic Control Center is designed to handle more information and respond more quickly and accurately. One of the features is the circular layout. In this way, many monitors can be seen from the seat, and at the same time, the distance between the persons in charge is closer and closer cooperation can be achieved. Next is the ergonomic display layout. The height of the display is adjusted so that it is within the viewing angle of the sitting person within 20 degrees, and the height of the step on the floor is adjusted so that the monitor is not hidden by the head of the person in front. . In addition to the layout, the number of displays has been doubled compared to the previous road control center. The amount of information projected on 156 55-inch panels can be handled up to about five times that of conventional models, enabling more complex decisions to be made more quickly. Furthermore, the display location and layout of each information can be changed freely, making it possible to respond flexibly to abnormal situations such as Expressway conditions and disasters.

  •  

    A large display that is more than 50 meters long in a straight line is rounded, and a large number of monitors are stored in a limited space. In addition, the circular layout allows information to be smoothly shared between staff members.

What kind of new functions have been adopted for the Kanazawa Regional Head Office Road Control Center?

-Expressway 's first integrated smart IC management and disaster recovery-

For smart ICs in the area, the new Kanazawa Regional Head Office Road Control Center has been consolidated to provide remote support. Through this initiative, we are pursuing management cost reductions and efficiency.
Another new feature is disaster recovery. This is a function that can distribute the system for processing each data of Expressway several places including Kanazawa Regional Head Office. By introducing this system, for example, even if the Nagoya Regional Head Office road control center is damaged, it is possible to manage approximately 840 km of the Expressway managed by the Nagoya Regional Head Office with the new Kanazawa Regional Head Office road control center. In Japan, where natural disasters such as earthquakes and typhoons frequently occur, we believe that it will become a very important function in the future.

-The latest earthquake-resistant structure that can withstand a seismic intensity of 6 or higher-

The Kanazawa Regional Head Office Road Control Center plays a role as a disaster prevention base in the event of a large-scale disaster. Therefore, it is located 3 km away from the coast outside the hazard map, and has the latest earthquake-resistant structure that can withstand a seismic intensity of 6 or more. In addition, equipped with a facility that can purify well water into drinking water so that drinking water can be supplied even if water is cut off, and a private power generation facility that can generate power for more than 72 hours, using propane gas that does not stop supply due to pipe damage, Fuel reserves are sufficient for more than 72 hours. As a countermeasure against inundation, a central system and an electrical room that are usually located on the first floor are installed on the upper floor. In addition, if another road control center is damaged, there will be a working space that can accept personnel from that road control center. Indeed, at the NEXCO CENTRAL Road Control Center, it is a facility equipped with various facilities and devices so that it can continue functioning in the event of any disaster.

As the latest road control center, how will the Kanazawa Regional Head Office road control center function in the future?

-Kanazawa Regional Head Office Road Control Center will play a safe future and backup function for NEXCO CENTRAL

The Kanazawa Regional Head Office Road Control Center has selected a location with a lower risk of earthquake than any of the road control centers within its jurisdiction. For example, in the event of a Nankai-Tokai earthquake, which is said to be likely to occur in the not-so-distant future, the Kanazawa Regional Head Office Road Traffic Control Center, which has a number of disaster prevention measures and disaster recovery functions, will provide backup for NEXCO CENTRAL It will take on the role of a site.
Yet another very important function is being planned as a road control center. It is remote centralized monitoring of structures. Currently, the deterioration and damage of structures are checked one by one with inspection equipment, but in the future, we aim to monitor them collectively at the center using sensors that utilize the latest technology. When this system is completed, management costs and efficiency will be improved, as well as the progress of deterioration and damage in real time, so that troubles can be prevented beforehand.
The Kanazawa Regional Head Office Road Control Center is a road control center that plays a very important role in NEXCO CENTRAL as a whole in the future of facility and equipment safety management and backup.
