In the article, it's highlighted that the intelligent transportation system is a comprehensive application of advanced technologies such as information technology, communication systems, sensing devices, control mechanisms, and computer processing. This system plays a crucial role in managing traffic across various areas, offering real-time, accurate, and efficient solutions for urban mobility. As part of its development, Yantai City launched an intelligent road traffic management service system project in May 2011, with the goal of completing the “one platform, seven systems†smart traffic system by the end of 2013.
One of the key components of this system is the video surveillance network. A total of 328 surveillance units are planned, including 28 high-altitude cameras installed on tall buildings to provide a broader view of city traffic. So far, 100 intersection cameras have been installed, with the remaining 228 expected to be completed by the end of 2013. These systems help monitor traffic flow and identify congestion points in real time.
Another important element is the electronic police system, which includes 103 units designed to detect violations like running red lights, illegal lane changes, and speeding. In addition to monitoring traffic, these systems also support public safety by assisting in criminal investigations and accident tracking.
The security bayonet system consists of 23 checkpoints strategically placed around the city to monitor all vehicles entering and exiting. According to Wang Hongbin from the Yantai Public Security Bureau, this system records vehicle movements and allows authorities to track their routes, enhancing overall security.
The traffic signal system has been upgraded with 99 new signal machines and 120 networked detection systems. It also includes bus priority features, where the green light is extended when a bus approaches, ensuring smoother transit for public transport users.
To improve traffic data accuracy, a traffic flow collection system is being implemented, adding 49 sensors on both intersections and road segments. This provides more reliable data for better traffic control and planning.
The traffic guidance system includes 41 digital signs, helping drivers choose optimal routes based on current conditions. With the introduction of parking space indicators, drivers can now find available spots more easily, reducing unnecessary travel and congestion.
Additionally, a mobile policing system enables officers to handle minor violations on-site using portable terminals. This reduces the need for drivers to visit traffic centers, making the process more efficient.
Overall, the intelligent transportation system represents a major step forward in urban mobility, integrating cutting-edge technology to enhance safety, efficiency, and convenience for city residents.
