TOKYO, May 24, 2022 - (JCN Newswire via SEAPRWire.com) - 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.

NEXCO is the first expressway operator in Japan to continuously monitor traffic conditions using these kinds of technologies. Highway operators need to monitor traffic flow and to detect incidents on expressways for traffic control. Most sensors in use today for this purpose are point sensors or cameras with a limited field of view. A large number of point sensors and/...
