1038 electronic monitoring coverage in Nanjing

Recently, the citizens came to the command center of the Nanjing Traffic Management Bureau and had just entered the hall. The 160 big screens in front of them let them exclaim that they were "too spectacular." On these screens, Nanjing’s traffic conditions and the panoramic views of the city’s roads are well-viewed, and traffic policemen rely on them to direct traffic. This soon-to-be-enabled command center has also ushered in the first public members of the community because of the arrival of the citizens.

"Cloud Traffic" command system: where 1038 monitoring components are congested, where there is a traffic accident, which vehicle has been violated and the screen is clearly visible.

Shocked!

This is the first time a reader enters the lobby of the command center of Nanjing Traffic Management Bureau. One reader looked at the 160 large screens on the wall that were continuously refurbished and could not help but exclaim: "This scene is only available in large American movies!"

The 160 large screens on the command center wall monitor the traffic conditions of various roads in Nanjing in real time. Wherever there is congestion, where a traffic accident occurs, which vehicle is in violation, or which vehicle has rolled a double yellow line, it is clearly seen on these screens.

The 160 large-screen images are provided by 1,038 monitors on the road, including 493 high-definition probes covering most of Nanjing's roads. Behind the 160 large screens is a nation's most advanced "cloud traffic" command system.

Then, how did such a “smart” system have high-tech and how did it direct traffic? The fifteen modern express readers followed the traffic police and conducted a journey of exploration.

Traffic violations, all in the eyes of the traffic police do not think there is no "electronic police", you dare to illegally, in fact, your violations, traffic police can see.

Of the 15 modern express readers who came here for the visit, 8 have private cars and there are also some illegal violations. They are very curious, their traffic violations, how did the traffic police shoot?

"Actually, the electronic police do not have to be just at the intersection." The head of the command center said that the 1,038 surveillances in the main city now have the function of shooting traffic violations. Subsequently, the traffic police of the command center demonstrated that a monitor installed at the entrance of the Jiangsu Provincial Hospital was cut into the big screen. On the screen, a Nanjing license plate of the Peugeot 307 sedan was running on the non-motorized vehicle and was leaning over. Stopped. Once the monitoring probe is closer again, the number plate is clearly recorded. The traffic police immediately informed the traffic police of the brigade's command room and asked the nearby traffic police to investigate.

“Not only the intersections, but most of the road sections, we can monitor them.” The command center’s official said that some of these monitored violations will be handed over to the Traffic Police Brigade in the area, which will be punished by these traffic police brigades. There are also some illegal activities. , will be broadcast live. Now there are 52 LED screens in the main city of Nanjing. From time to time, illegal information of some vehicles will be displayed, and these are taken by these monitors.

The illegal behavior of being “lived in full” will not be punished. According to the reporter of the Modern Express, the next step is that the traffic control department will network these monitoring and illegal exposure systems so that all traffic violations will be directly exposed. After driving, do not think that there is no "electronic police", you dare to casually violate the law, in fact, all your violations, traffic police are clear to see.

The wireless police patrolled the police to deploy more scientific and timely deployment of the police force to achieve the shortest time and fastest speed and use the police force where it is most needed.

In 1038 electronic surveillance, the intersections were scanned one by one in the control of the traffic police in the command center.

“This is our wireless police patrol.” The person in charge of the command center told readers of Hyundai Express that the Nanjing traffic police patrols now adopts a combination of online and offline modes. Online, the traffic police of the brigades still ride police and drive police cars to patrol their area. On the line, these monitors are used to scan the intersections and road sections.

This wireless police patrol is conducted in 24 hours. During the on-line patrol, an accident was accidentally broadcast at the entrance of the Yixian Bridge at Longxu Middle Road. When a motor vehicle turns right, it rubs against a straight electric bicycle. The traffic volume at this intersection is very large. Soon after, the junction is blocked.

Must immediately send traffic police to groom. At this time, the police positioning system started. The monitoring screen showed that seven traffic policemen were patrolling nearby, and one of the traffic policemen was only about 100 meters away from the incident. As a result, the command center traffic police passed the radio and called the patrolling traffic police to rush to the scene. One minute later, the traffic police appeared in the video surveillance and the scene of the accident was quickly removed.

"This system will make our police deployment more scientific." The traffic police said that the deployment of the police force in a timely manner, to achieve the shortest time, the fastest speed, the police use the most needed places, the efficiency will be several times higher.

With the blacklist system, a deckcar has no place to hide and a car is monitored. Within a second, the number plate will be intercepted and compared with the vehicle registration system.

In the "cloud traffic" command system, there is also a system that also exerts its power. This is the blacklist system. "For example, like a deck car, there is almost no hiding place in Nanjing." The traffic police told the readers of Modern Express. This violation of the law, the Nanjing Traffic Control Department has been a severe blow. But before, mainly rely on the traffic police to "take a chance," only after the traffic police stop the car at the scene, the number plate is entered into the policing system, in order to compare whether it belongs to the deck car. But now, with this black list system, the deck car has no place to hide.

Originally, this blacklist system also contained a number plate recognition system. After a car is monitored and monitored within one second, the number plate is intercepted and compared with the vehicle registration system. If the number plate does not match the registered model and color, it will be blacklisted. However, some drivers deliberately choose some models and vehicles of the same color when decking. There are also ways to do this. As long as the owner of the vehicle warns that his car has been decked, the traffic police will enter the blacklist system after confirming it. Once the car is found at an intersection, it will be captured and sent to the police. Interception and investigation.

Tide signal lights, according to the flow of the current signal of the tide signal, there are 41 roads in Nanjing, 287 intersections have been installed.

Mr. Liu, a reader of Hyundai Express, had a private car. During the visit, he asked a question: “Why are the green lights at some intersections different in time?” Mr. Liu said that for example, Beijing West Road, in the morning, the green time from east to west It took more than 60 seconds, but by the evening peak, the green time from east to west was reduced by 10 seconds. At night, the green time was only 30 seconds.

The head of the command center smiled and said that this was because the signal lights had become "smart." The command center of Nanjing Traffic Management Bureau controls the intelligent signal control system. At present, in the 14 square kilometers of central city of Nanjing, the intelligent traffic signal area of ​​95 intersections has been networked and controlled, and coordinated and control of signal timing has been carried out.

"Mr. Liu said that it was actually a tidal signal." The official said that at the early morning peak of Beijing West Road, there are more cars from east to west, but there are fewer cars from west to east, so the green time from east to west is long. At one point, but at the late peak, the traffic flow is in the opposite direction. Therefore, the timing will change back. In the evening, the traffic volume is low, and it is necessary to take into account the traffic at each intersection. The green time will be shorter. At present, there are 41 roads and 287 intersections in Nanjing that have been installed with this type of tidal signal. In addition, “green wave control” has been implemented at 1,014 roads on 154 roads.

“Microwave Detection” helps owners avoid the congestion based on the principle of infrared microwaves. How many vehicles pass through and what direction they are traveling can all be detected. Coupled with a system such as a GPS system on a taxi, after integrating multiple data, the "congestion index" of the road can be measured.

Because before the Youth Olympic Games, a number of road projects in Nanjing were launched, together with the increase in motor vehicle ownership, all roads in Nanjing are now very congested.

“I drive out every day and I don’t even know if the road ahead is blocked or not, and it would be too late to get around after I was stuck in it.” Ms. Guo, a reader of Modern Express, said that if we can grasp the information on the road ahead, it would be nice.

Ms. Guo’s request is precisely what the traffic control department is currently trying to achieve. "We are building a huge intelligent traffic guidance system." The command center official said that the current induction system has already reached a certain scale. For example, in the streets of Nanjing, 52 LED induction screens have been installed, using green, yellow and red colors. Mark congestion on surrounding roads. Also told through the 114, mobile phone text messages, "@ Nanjing Road News Room", radio conditions and other ways to tell the driver, which road blocked, how to go.

However, these are not enough. The traffic control department is also currently encrypting the induction screens in the urban areas, so that drivers can take the "wrong way".

However, what readers are curious about is whether the road is blocked or not, whether it is through monitoring or not, then it is concluded? “It is not that simple.” The command center official said that video surveillance is indeed a means, but only It gives an intuitive impression, but what exactly does the road look like? How many cars pass in an hour requires another high technology.

This high-tech is "microwave detection," the person in charge explained that this type of microwave detection, based on the principle of infrared microwaves, how many vehicles pass, what is the direction of travel, all can be detected. Coupled with a system such as a GPS system on a taxi, after integrating multiple data, the "crowdness index" of the road can be measured.
