In a recent visit to the command center of the Nanjing Traffic Management Bureau, citizens were amazed by the high-tech and real-time monitoring systems in place. As they entered the large hall, they were greeted by 160 massive screens that displayed live footage of the city's traffic conditions. The panoramic views of roads and intersections allowed traffic officers to monitor and manage traffic efficiently. This advanced system has now opened its doors to the public for the first time, offering a glimpse into the future of smart urban mobility.
The "Cloud Traffic" command system is equipped with 1,038 surveillance cameras across the city, including 493 high-definition ones that cover most of Nanjing’s main roads. These cameras not only detect traffic congestion but also capture violations such as illegal parking, running red lights, or crossing double yellow lines. All this information is displayed on the large screens, giving traffic police an immediate overview of the city's road network.
One visitor, a reader from Modern Express, was stunned by the high-tech environment. “This scene looks like something out of an American movie,†he said, marveling at the real-time updates and seamless integration of technology. The system allows traffic officers to quickly identify and respond to incidents, ensuring smoother traffic flow and improved safety.
The command center also uses a "blacklist" system to track vehicles involved in repeated violations. Once a vehicle is flagged, it becomes nearly impossible to hide. The system can instantly compare license plates against the registration database, making it easier to catch unregistered or modified cars.
In addition to video surveillance, the city employs microwave detection technology to measure traffic flow. This system, combined with GPS data from taxis, helps calculate the "congestion index" of roads. It provides more accurate insights than traditional methods, enabling better decision-making for traffic management.
Nanjing has also implemented intelligent traffic signals known as "tide signals," which adjust green light durations based on real-time traffic patterns. For example, on Beijing West Road, the green light duration changes throughout the day to accommodate varying traffic flows. This adaptive system helps reduce congestion and improve overall traffic efficiency.
To further assist drivers, the city has installed 52 LED guidance screens that display real-time traffic conditions using color-coded indicators. Drivers can also receive updates through mobile messages, social media, radio, and other platforms. Plans are underway to expand this system and provide even more detailed navigation assistance.
Overall, Nanjing is transforming its traffic management system into a highly intelligent and responsive network. With real-time monitoring, advanced analytics, and efficient coordination, the city is setting a new standard for smart transportation. Whether through surveillance, signal control, or data-driven insights, the goal remains the same: to make commuting safer, faster, and more predictable for everyone.
