The growth of Haikou led traffic lights

The growth of Haikou led traffic lights:

 Since the founding of the People’s Republic of China for 70 years, especially since the establishment of the special economic zone in Hainan

Province, the urban transportation facilities in Haikou have been continuously upgraded. In 1989, Haikou City introduced 10 sets of traffic

light systems from Australia, installed in Jiefang West Road, Datong Road, Huaqiao Building, etc. intersection. The story of Haikou traffic

lights reflects the changing changes in a city.
Shortly after the heavy rain, Liu Wei, the captain of the traffic police detachment facility brigade, took the police to Jiefang West Road, Datong

Road and other places to check the traffic barriers and traffic lights at various intersections. The traffic lights in these old towns are like his old

friends.
City Traffic Police Detachment Facilities Brigade Captain Liu Wei:

In 1989, Haikou City introduced 10 sets of traffic light systems from Australia, mainly installed at Jiefang West Road, Datong Road, Huaqiao

Building and other intersections. At that time, I just joined the work and witnessed the first batch of traffic lights landing in Haikou.
After the municipal government introduced these batches of traffic lights from abroad for the first time, Liu Wei was one of the three police

officers who were responsible for maintenance. Since then, he has had an indissoluble bond with the Haikou traffic signal.
City Traffic Police Detachment Facilities Brigade Captain Liu Wei:
The early Haikou traffic lights were ordinary light bulbs, and their life span was only a few thousand hours, so the city’s traffic lights were often

bad. Like this high pole, it is the most headache. We often have several people carrying the ladder and climbing up to replace the bulb.
  After Hainan was established in the province, the intersection of traffic lights in Haikou increased with the rapid increase of the number of motor

vehicles. However, due to the lack of networking, it was necessary to adjust the release time of the traffic lights at that time, and the police had to

go to the host of each intersection to operate.
City Traffic Police Detachment Facilities Brigade Captain Liu Wei:
 At that time, we spent a lot of manpower and material resources, kept at the intersection for a long time to deploy, and the effect was not satisfactory.

Nowadays, it is intelligent networking, and our traffic lights can be adjusted in one click.
Haikou traffic lights have grown from nothing, and now have grown to more than 380, and all use LED lights, Haikou traffic police are also constantly

exploring how to use technology to serve urban traffic management. In 2004, Chen Dong, who just graduated from the police school, almost participated

in the whole process of intelligent transportation management in Haikou.
City Traffic Police Detachment Science and Technology Section Chief Chen Dong:
At that time, the traffic lights at Haikou were very simple. There was only a simple manual control method, and the traffic flow and data at the traffic lights

intersection could not be controlled.

In 2007, the Haikou Traffic Command and Control Center was completed and the traffic signal control system was put into use. In 2008, 12 roads such as

Binhai Avenue and Renmin Avenue were controlled by green waves. In 2014, the road traffic flow monitoring and early warning system was completed and

put into use; 2018 The “Haikou Traffic Brain” project began to be implemented.
City Traffic Police Detachment Science and Technology Section Chief Chen Dong:

 We have several special highlights, one is that the city’s traffic lights will realize artificial intelligence control, through artificial intelligence, through a fully

automated way to control the duration of the city’s traffic lights; the second is that we can communicate the city’s traffic conditions There is a more comprehensive

and intuitive perception; the third is a more scientific and quantitative judgment on the decision of the entire traffic management.
Chen Dong said that after the completion of the “Haikou Traffic Brain”, it can also provide more accurate and effective service guidance for the frontline police,

and improve the rapid response capability of the frontline traffic police, including the handling of police and traffic accidents.
