This document reviews research on intelligent traffic control systems for smart cities using computer vision. It discusses various algorithms that have been proposed for tasks like vehicle tracking, incident detection, and parking availability. It also describes some smart phone applications and projects from companies that aim to improve transportation management systems. While progress has been made, the document notes that challenges remain like dealing with different lighting conditions and weather events. It concludes that more work is still needed to better implement real-time traffic management in smart cities.
