HANGZHOU, China, July 24, 2020 /PRNewswire=KYODO JBN/ --

- Traffic continues to grow in every major city. But how do you beat congestion

in these restricted urban spaces? In China's ancient-walled city of Xi'an,

they're adopting an intelligent traffic management system based on Hikvision

technology - and boosting traffic flow while reducing journey time.

The Chinese city of Xi'an, known as Chang'an in ancient times, was the center

of ancient oriental civilization. Thirteen dynasties spanning Chinese history

have chosen Xi'an as their capital. Today, Xi'an is not simply a part of

history: it's a high tech hub, renowned across China for its scientific

research and education, manufacturing, technology, and transportation.

The challenge: allowing a city to grow and flow within ancient walls

In spite of being a modern hub, Xi'an still retains its 'checkerboard' layout

from the Tang Dynasty, complete with its border of tall and ancient walls.

Nevertheless, while economic growth has enabled the city to develop, the walls

place great restrictions on the city's daily movement - especially to its

burgeoning traffic. Vehicles can only enter and exit through the city gates,

but with some three million vehicles in the city, the limited number of

entrances was beginning to cause serious congestion.

What's more, there are also many ancient ruins in the city, which were further

limiting the development of the urban area. Plus as of 2018, the city was home

to over 10 million people, while the number of construction projects was

steadily increasing.

Managing a growing city while protecting its history presented a serious

challenge to Xi'an. So to address this, Xi'an Urban Traffic Administration

turned to Hikvision and its intelligent cameras.

The Solution: an intelligent traffic management system from Hikvision

"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," says 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 Hikvision's core advantages in urban

transportation intelligence, employing AI-powered video to create a powerful

traffic sensing system. "Effectively, we are building a bridge between an

intelligent digital world and the physical urban transportation network in

Xi'an," explains Lihu.

The technical solution

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 in three key ways.

1. Comprehensive road traffic violation monitoring

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. What's more, the latest sonar monitoring equipment is

being used to detect illegal use of car horns in banned areas.

2. Visual integrated command and dispatching platform

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.

All data is aggregated and dynamically displayed on a large screen in the

command and control center. In the event of a traffic incident, the system

generates dispatch recommendations intelligently, according to the location and

distribution of traffic police officers throughout the city. Those closest to

an incident receive an automated message to their mobile terminals, enabling

them to arrive at the scene quickly.

More importantly, 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 put evasive measures

in place before serious issues arise.

3. Improved vehicle flow capacity with intelligent signal control

The Xi'an traffic management team also employs congestion management practices

to ease the flow of traffic, largely 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.

Benefits: Traffic throughput up by 10%, journey time down by 12%

The Xi'an traffic management system has now been trained with a wealth of

traffic data, including Hikvision video, enabling it to build multiple

intelligent algorithms for managing congestion in the city.

First of all, 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%.

What's more, driver behavior is improving, and drivers are becoming more

compliant with the rules of the road. Traffic law enforcement data reveals that

traffic offenses are generally decreasing, with traffic violations dropping by

some 30% in one short-term observation.

Additionally, thanks to the proactive traffic incident warning function, the

incident detection rate has also increased by more than 30% compared to the

traditional model. With the continuous optimization of the system algorithm,

plus ongoing installation of monitoring equipment, the accuracy of this

identification will only improve.

In the process of urbanization, tackling congestion is not only about improving

the flow of the transportation network: it's also basic governance for building

a smart city.
