China’s Xi’an deploys AI-based intelligent traffic management system
Chinese city Xi’an has selected Hikvision for the deployment of an intelligent traffic management system, the latter said in a release.
“Xi’an’s city walls make it impossible to increase the size of the urban area. So it was only through technology that we could allow the modern city to grow and develop,” said Lihu Ma, the Project Manager from Hikvision. “A core part of the Hikvision solution involves our AI-powered video technology.”
The Xi’an traffic police worked with experts from Hikvision, as well as urban planning experts, internet service providers and other technology companies, to design and implement an intelligent traffic management system. The construction of this system fully utilizes AI-powered video to create a traffic sensing system. “Effectively, we are building a bridge between an intelligent digital world and the physical urban transportation network in Xi’an,” said Lihu.
The intelligent traffic management system analyzes comprehensive and detailed data about the movement of traffic through the urban Xi’an area, and uses the insight gathered to make the flow of traffic more smoothly.
Xi’an traffic police have installed Hikvision’s Checkpoint Capture Cameras and Intersection Violation Capture Units as part of a monitoring system that can detect illegal vehicle behavior at intersections.
These full view ultra-high zoom cameras record vehicles making illegal maneuvers – such as running red lights, making banned turns and illegal lane changes – in real time.
Using real-time video streams from Hikvision Traffic Flow Capture Cameras, a number of road condition perception technologies, plus intelligent mobile applications, Xi’an traffic police has created a visual command and control center, coupled with an intelligent police dispatch system.
The intelligent traffic management system uses advanced machine learning capabilities to gain insight into typical congestion patterns, in order to actively identify potential traffic events before they happen. By analyzing large volumes of road condition data and information from Hikvision’s intelligent video cameras, the system can predict which intersections are most prone to congestion and when, enabling traffic police to adopt measures to avoid congestions.
The Xi’an traffic management team also employs congestion management practices to ease the flow of traffic, through the optimization of signal timing.
Using Hikvision intelligent video cameras coupled with augmented reality (AR) technology, the intelligent traffic management system analyzes traffic flow data and dynamically alters the timing of signal lights accordingly. It will monitor traffic flow, queue length and average driving speed in all directions of intersections in real-time, automatically adjusting signal timing to optimize the flow of vehicles.
The Xi’an traffic management system has now been trained with traffic data, including Hikvision video, enabling it to build multiple intelligent algorithms for managing congestion in the city.
The company noted that map-based congestion reports suggest that Xi’an’s congestion rankings have improved significantly. In fact, compared with the test results of pilot roads before the system went live, intelligent signal control alone has increased the throughput of traffic by 10%, while the average vehicle journey time is reduced by about 12%.
Also, the incident detection rate has also increased by more than 30% compared to the traditional model.
