The smart and scalable urban traffic control system can be seen as an Internet of smart intersections (things), where each intersection is an intelligent entity equipped with an artificial intelligence (AI) brain called schedule-driven intersection control (SchIC) to optimize traffic flow, using predictive traffic flow information from neighbors.
