ICT-based traffic signals change their timing according to the number of vehicles. Which benefit does this illustrate?

Correct answer: Efficient resource management using real-time data

Sensors or connected systems can collect current traffic information and use it to adjust signal timing. This data-driven response can reduce unnecessary waiting, improve traffic flow, and use road capacity more efficiently. Option A correctly describes efficient resource management based on real-time data. The system does not make fixed decisions without data, remove communication, or operate merely as decorative lighting.
