Tomei Expwy Akabuchigawabashi renewal construction

Main measures

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.

Expressway Renewal Project

Of the 2,077 km of Expressway our service area, approximately 60% of the sections exceed 30 years after opening, and are markedly deformed due to aging, increased traffic on large vehicles, the effect of deicing agents, and abnormal weather in recent years. Has become apparent.
Expressway Renewal Project aims to minimize the life cycle costs (expenses required for maintenance, from planning, design, and construction, to maintenance) of Expressway structures, preventive maintenance (maintenance methods to be performed before failures or malfunctions occur), and improve performance. This is done to keep the functioning of the Expressway network healthy over the long term by taking necessary and effective measures from a viewpoint.

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.

Expressway Use wisely

Promotion of ETC 2.0 service

“ETC2.0” Expressway In addition to paying tolls, we provide useful services for drivers, such as avoiding traffic congestion and supporting safe driving.
With the aim of upgrading road management and traffic jam information using ETC 2.0 services, we will work with related organizations on the development of safe driving support technology and charges for reducing congestion. In order to further increase usage, we will work to support the spread of ETC2.0 on-board devices.
In order to realize a favorable driving environment as a new fee policy, Expressway We will leave the station temporarily and try to refuel at a designated gas station or take a break at the nearest roadside station.

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.
