Technology development efforts
NEXCO CENTRAL is promoting technological development as a group in collaboration with various companies and universities in order to provide a safe, secure and comfortable Expressway space.
Building technology to prioritize safety above all else
We are developing technology to provide a safe, secure and comfortable Expressway space.
Development of non-destructive inspection technology for cable-stayed bridges
We are developing a technology to detect rust on water and steel materials inside by using a neutron beam for places where it is difficult to inspect cables such as cable-stayed bridges. In this way, we aim to carry out inspections and surveys efficiently.
Development of pavement repair method by deep improvement
Due to the Large application of high-performance pavement (drainage pavement), the damage to the pavement tends to deepen. As a result, the lower road base (the lower layer of the pavement) is becoming weaker in various places.
We are aiming to establish a technology to efficiently repair the weakened lower road base by injecting cement milk etc. from the road surface.
Development of tunnel lining regeneration method
We are developing construction methods and materials that regenerate the lining function with new concrete by removing part of the old lining concrete of the tunnel. This aims to reduce maintenance work in winter by improving the load-bearing performance of aging lining concrete and reducing water leakage into the tunnel.
Building technology to enhance and evolve Expressway
We are developing technologies to enhance the functions and evolve of Expressway.
Anomaly detection by AI image processing of CCTV camera images
AI analysis of images from swivel / zoom cameras installed on Expressway automatically detects the occurrence of accidents and traffic jams, and realizes advanced maintenance by detecting abnormal situations at an early stage. I am aiming.
Construction of technology that realizes new value creation that adapts to environmental changes such as digitization (DX) and decarbonization
We are developing technologies with an eye on future changes, such as the utilization of digital technology and the realization of a carbon-free society.
Autonomous driving support by road-to-vehicle coordination system
By transmitting information such as accidents and traffic jams that cannot be detected by the automobile to the autonomous driving vehicle faster and more accurately, it is possible to change routes and avoid collisions. We are aiming to promptly collect the information necessary for that purpose and provide it to the following vehicles, as well as centrally grasp it at the road control center and realize autonomous driving support.
Initiatives to introduce environmentally friendly concrete
Concrete materials, which are often used in the Expressway business, generate a large amount of CO2 in the cement manufacturing process. We are making efforts toward the introduction of environment-friendly concrete that leads to decarbonization.
Technology development for autonomous driving of snowplows
Due to the aging of the population and the decline in the working population, a shortage of workers has become apparent due to the aging of the population and a decline in the working population, so we are developing technology for automated driving.
