Smart maintenance highway (SMH)

Expressway infrastructure managed by NEXCO EAST Group is aging year by year, and it is expected that the deterioration of road structures will increase at an accelerating rate in the future.
Furthermore, as a social issue, the working-age population has already begun to decline, and the generational change in engineers is rapidly progressing, making securing the quality and quantity of maintenance engineers a major issue within the company.
On the other hand, advances in technologies such as ICT, robotics, and AI are remarkable day by day, and the active use of these technologies is being considered in various industries.
At such "points of change" both internally and externally, we will continue to pursue safety and security, which is our group's mission, by promoting the SMH project, which aims to best match engineers and ICT, etc., as a solution to overcome issues. Masu.
