Tomei Expwy Akabuchigawabashi renewal construction

Planned maintenance of road structures

Starting with the opening of the Meishin Expwy 1963, the Japanese Expressway network gradually Large and became an important infrastructure supporting Japan's society, economy and people's lives. During this time, the maintenance and management of the Expressway while introducing the latest technology, such as daily inspection of structures, repair of damage, improvement of running environment such as construction of high-performance pavement, preparation for large-scale earthquakes by seismic reinforcement of bridges, etc. I've been working on
In order to maintain the Expressway network in a healthy state and pass it on to the next generation, we will conduct periodic inspections and perform early maintenance and repair. In addition, we will steadily implement large-scale replacement of structures and seismic reinforcement work to enhance the safety and reliability of Expressway.

Scheduled construction in 2018

Efforts to advance the project effectively

Examples of traffic restrictions

Promotion of seismic reinforcement measures

Based on the damage situation of the bridge in the Kumamoto earthquake Expressway We will further promote the seismic reinforcement of bridges so that you can use.

Example of earthquake-proof reinforcement measures: Completely self-supporting structure (rocking pier)

Steady implementation of maintenance cycle

Inspection is the basis for early detection of changes in road structures, taking appropriate measures, and maintaining good conditions over the long term. In addition to daily inspections, detailed inspections of structures such as bridges and tunnels are conducted by close visual inspection once every five years in accordance with laws and regulations. For structures that have been confirmed to have been damaged by inspection, repair plans will be established at an early stage.

Strengthen control of vehicles that violate weight

We are strengthening control of vehicles that violate weight, which has a major impact on the deterioration of road structures and can lead to serious traffic accidents. A special enforcement team is located at the entrance of the IC, etc. Expressway In addition to action orders requiring exit from Japan, more severe action orders have been implemented, such as reducing the load on serious violators (reducing 292 shipments in FY2017). Criminal prosecution is also carried out for malicious violators.
In addition, as a new initiative, we are strengthening the application of large-volume and frequent discount suspension measures to violators, and are working on the regular control of vehicles that violate weight by developing automatic measuring devices.

Enforcement status of weight violation vehicles

Expressway Use wisely

Promotion of ETC 2.0 service

Expansion of planned discounts

“Central Nippon Expressway Pass (CEP)” and “Japan Expressway Pass” for two-wheeled vehicles for foreign visitors to Japan, which are expected to increase further due to drive plans linked with local public organizations and tourist facilities, Tokyo Olympics and Paralympics Increase the convenience of round-trip discount products such as the “Touring Plan” Expressway We aim to promote the use of We will also consider rate adjustments and discounts for traffic congestion.

Congestion measures

Tomei Expwy Near the Yamato tunnel, ChuoExpwy near the Kobutsu tunnel, Tokai-Hokuriku Expwy Hida-Kiyomi IC ~Oyabe Tonami JCT Is progressing.
In FY2017, provisional three-lane operation was performed for approximately 8 km between Higashi-Meihan Expwy Suzuka IC and Yokkaichi IC (In-bound line), and gaze guidance using LED lights near Suzuka IC We started operation of traffic congestion measures (drive assist light). Ken-O Road Hachioji JCT has started operation of the main lane with two lanes.
As a result of the above, the traffic congestion in the countermeasures section decreased (1.6 thousand km / hour), and had a certain effect.However, the traffic volume of the entire roads under our jurisdiction has been increasing compared to FY2016, especially during Golden Week and Bon Festival. Congestion increased due to the concentration of traffic during the traffic congestion period.
In addition, as countermeasures against congestion of parking spaces at rest facilities, we are promoting the effective use of parking spaces and providing congestion information.
In addition, since FY2017, "Expressway Drive Advisor," who has become familiar with local traffic characteristics, has been providing more detailed information, such as introducing points to avoid traffic jams during traffic congestion periods.

Information provided by Drive Advisor

Traffic accident countermeasures

In order to prevent traffic accidents, we will develop hardware measures to improve the driving environment, such as improving high-performance pavements and guardrails, and building high-intensity lane marks, and software measures to raise customer safety awareness.

Traffic safety awareness activities

Free business trip course NEXCO CENTRAL Expressway We conduct traffic safety awareness activities such as holding a road safety seminar and a road safety campaign.

Promotion of business to prevent serious accidents

To prevent frontal collision accidents in the provisional two-lane section, in fiscal 2017, wire ropes were installed on some sections of the Tokai-Kanjo Expwy, Kisei Expressway, and Maizuru-Wakasa Expressway in place of conventional rubber poles.
Although there were 17 accidents involving contact with the wire rope, no head-on collisions occurred. In FY2018, we will further expand the installation sections.

Changes in the number of fatal accidents

Strengthening measures against reverse running

Expressway The reverse run of is extremely dangerous, as the ratio of fatalities and injuries is 4 times that of other accidents and 40 times that of fatal accidents.
Within our jurisdiction, about 30 reverse run cases occur annually. Expressway With the aim of "zero reverse running accidents in Japan", we will take multi-layered measures in terms of hardware and software.

Hard measures

All to prevent reverse running Expressway Road markings, rubber poles, and arrow signs were installed at the junction. In fiscal 2018, as a result of public recruitment of reverse-running countermeasure technology, we will further develop reverse-running countermeasures on the site, including technologies that are recognized as being effective by the Expert Committee.

Soft measures

In addition to calling at rest facilities, etc. under the keyword “Lostly Reverse”, we are conducting traffic safety awareness activities using mass media such as TV commercials and newspaper advertisements.

Trends in reverse run cases and reverse run accidents

Example of reverse recruitment technology

Measures for entering pedestrians and bicycles

Due to wrong roads or mistakes Expressway There are many entrances to the area, and we are promoting measures to prevent physical entry by using a signboard at the entrance of the IC, clearly indicating the direction of travel using road markings, and installing rubber poles. With this approach, Expressway Expected to prevent accidents and prevent accidents.

Resistant to disaster Expressway

At the time of a large-scale disaster Expressway One of our important roles is to secure a quick emergency transportation route using the network. In preparation for large-scale disasters and heavy snow, we are strengthening cooperation with related organizations and strengthening disaster prevention functions.

In response to the national plan for specific emergency response activities in the Nankai Trough Earthquake and the plan for specific emergency response activities in the earthquake directly under the Tokyo Metropolitan Government, Expressway In order to secure a quick emergency transportation route using the network, we have stockpiled materials and equipment for large-scale disasters. In addition, we conduct disaster prevention drills and evacuation guidance drills for the purpose of ensuring the safety of our customers.

Strengthen traffic security during heavy weather and other stormy weather

In order to avoid traffic closure due to heavy snow as much as possible, we are strengthening the snow removal system, increasing the number of surveillance cameras for early detection of stuck vehicles, and deploying rescue vehicles.
Also, advance public relations when heavy snow is expected and strengthen cooperation with related organizations, Expressway We are working to secure network functions. In light of the heavy snow events in the Hokuriku region in the winter of fiscal 2017, we will promote efforts to control large-scale vehicle retention and minimize traffic closure times.

Reform maintenance and service business operations with an eye on 10 years ahead

Capture dramatic changes in the environment, such as the development of IoT (Internet of Things), big data, artificial intelligence (AI), etc. in response to the decline in the population, an increase in aging social infrastructure, and the shortage of employees due to the increase in business volume. We will fundamentally review the current business methods and consider a new business environment through a future-oriented paradigm shift.
