Expressway Infrastructure Monitoring refers to the continuous or periodic assessment of the physical condition and operational status of highway assets, including pavement, bridges, tunnels, signage, and drainage systems. Sensor technologies such as distributed fiber-optic sensing, cameras, and vibration monitors collect data that AI systems analyze to detect structural anomalies, surface degradation, and safety risks. Applications include predictive maintenance, asset management, and real-time alerting for transportation authorities.
NEC Corporation has deployed an AI-based traffic monitoring system to Central Nippon Expressway Company Limited (NEXCO CENTRAL). The system uses fiber-optic sensing and AI technologies to visualize traffic conditions, such as the location, speed, and direction of travel, from vibrations produced by vehicle movement.
