In the article, it is mentioned that the intelligent traffic system in Yantai City was launched in May 2011 with the goal of completing a comprehensive "one platform, seven systems" smart traffic management service by the end of 2013. This system aims to enhance urban traffic control and improve the overall transportation experience through advanced technologies such as information technology, communication, sensing, control, and computer systems.
One key component of the project is the video surveillance system, which includes 328 units—28 high-altitude cameras and 300 intersection cameras. These systems allow the command center to monitor both local and broader traffic conditions. By the end of 2013, all 300 intersection cameras were expected to be fully installed, significantly improving real-time monitoring capabilities.
The electronic police system, consisting of 103 units, is designed to capture various traffic violations such as running red lights, illegal lane changes, and more. Additionally, it supports law enforcement in tracking criminal activities and managing major traffic incidents.
A security bayonet system with 23 units was also established around the city, forming three layers of defense to ensure all vehicles entering or leaving Yantai are monitored. This system allows for detailed tracking of vehicle movements, strengthening the city's public safety network.
The traffic signal system involved updating 99 signal machines and optimizing 120 intersections. It also included 25 demonstrations of bus priority signaling, where the green light is extended when a bus approaches, helping to reduce delays for public transport.
To collect accurate traffic flow data, 49 additional sensors were added—not just at intersections but also on road sections. This approach provides more reliable data, essential for efficient traffic signal control.
The traffic guidance system features 41 display screens, including large color screens, tunnel displays, and traffic guidance panels. These help drivers make informed decisions about their routes and parking options, reducing congestion and travel time.
The mobile policing system enables officers to handle minor violations on-site using mobile terminals, streamlining the process and allowing fines to be paid immediately. Digital police stations further enhance coordination between field officers and the command center.
Overall, the intelligent transportation system represents a significant advancement in urban mobility, integrating cutting-edge technology to create a safer, more efficient, and user-friendly traffic environment. Its applications extend beyond traffic control to include passenger flow management, expressway coordination, and vehicle dispatching systems.
