Zhengzhou Expressway traffic big data disclosure： the speed has increased by nearly 10% in three months, and the congestion index has dropped by 8.5%.

The expressway in Zhengzhou has been "fast" recently-the reporter recently obtained a big data of expressway traffic from the Public Security Traffic Management Bureau of Zhengzhou Public Security Bureau (hereinafter referred to as "Zhengzhou Traffic Police"): since June this year, the traffic congestion index of urban expressways in the morning and evening rush hours has decreased by 8.5%, and the average speed has increased by 9.3%; The duration of morning rush hour dropped from 124 minutes to 81 minutes, and the duration of evening rush hour dropped from 93 minutes to 70 minutes.

You didn’t watch the navigation until you drove. These traffic policemen saw the evening rush hour from the morning rush hour.

Do you turn on the navigation to see the road conditions before starting the car? Like you, you are concerned about real-time road conditions, and every traffic policeman in Zhengzhou Traffic Police Traffic Command Center.

"In the morning and evening rush hours, our police force will arrive in advance to monitor the road conditions in real time." Zhang Hao, director of the Traffic Command Center, told reporters.

Zhang Hao keeps a habit of sending the information of expressway conditions to the leaders in charge at regular intervals every day before the morning and evening rush hours. On this day, Zhang Hao must understand and explain which section of Zhengzhou city is congested, why it is congested and how to solve it.

Wang Kai, head of the service management post of the Traffic Command Center, introduced that the traffic conditions are updated every 5 minutes on the display screen of the traffic command center lobby, and the latest traffic conditions are released in real time.

"Like this, the agricultural road is congested, and we immediately issue early warning information through the platform to remind car owners to bypass." Wang Kai said that the traffic situation platform of the traffic command center marked the sections of conventional urban expressways that are easily blocked on the Internet navigation service platform. In addition, when there is a serious congestion alarm, arrange a special person to issue a congestion warning on the platform at the first time to guide the owner to avoid the congested road section.

In case of morning and evening peaks, holiday trips or bad weather, the effect of this platform is more obvious.

Before the owner of the accident called the police, the traffic police arrived first.

To solve the problem of "eyesight" in finding the congestion of viaducts, how to solve the crux of the slow "foot force" in unblocking?

Zhang Hao introduced that on the basis of remote video inspection, in order to ensure the effect of congestion control, the traffic command center strengthened the integration of service and command work, and realized "early detection, early disposal and early recovery" of congestion warning.

At present, the Traffic Management Bureau of Zhengzhou Public Security Bureau and various detachments have built a two-level traffic command center. When encountering a traffic jam alarm, the traffic police detachment in the jurisdiction of the road section will immediately order the nearest police force to deal with it.

"In the event of congestion, the iron rider needs to arrive at the scene within 3 to 5 minutes and be disposed of in 15 minutes." Zhang Hao said that through the linkage between the Traffic Management Bureau and the detachment, the time for the traffic police to arrive at the scene has been reduced from nearly ten minutes to five minutes.

Zhang Hao remembers such a warning. One morning, two cars collided on the Longhai Elevated Road at the peak. When the fighters arrived at the scene, the owner didn’t care to call the police.

The data shows that since June this year, the traffic congestion index of Zhengzhou urban expressway has dropped from 1.581 to 1.446 in the morning and evening rush hours, down by 8.5%; The average speed increased from 52.131 km/h to 56.976 km/h, an increase of 9.3%; The alarm of traffic jam and traffic accident in Zhengzhou urban expressway decreased by 41.2% and 7.4%.

Set up a waiting point for wrecker during peak hours.

The expressway has a large traffic volume and high speed, and collision and rear-end collision accidents occur from time to time. Most vehicles can move by themselves, withdraw quickly and compensate quickly. When encountering an accident that cannot be moved, not only the traffic police need to arrive quickly, but also the trailer needs to clear the obstacles.

Zhang Hao said that the traffic command center has sorted out 25 high-risk traffic accident sections on urban expressways, and set up waiting points for wreckers during rush hours. If accidents or faulty vehicles are found to affect the expressway traffic, they will be towed to a place that does not affect the traffic for temporary parking, and then towed to the parking lot involved after the rush hour.

"These 25 high-risk traffic accidents have been dynamically updated." Zhang Hao said that for expressways with slow speed, the traffic command center can check the road conditions in real time, and the wrecker can change its flow at any time.

The reporter learned that since June, the morning rush hour in Zhengzhou City has dropped from 124 minutes to 81 minutes, and the evening rush hour has dropped from 93 minutes to 70 minutes. "In the past, you may have to go out to work more than an hour in advance, but now you can reduce the time by 20 to 40 minutes." Zhang Hao said that only when the expressway is "fast" will the owners spend less time on the road.

Zhengzhou traffic police also reminded the majority of car owners that it is not enough to rely solely on the efforts of the traffic police if they want the expressway to be fast and smooth. When driving, they should abide by the signs and markings, do not change lanes at will, use the turn signals correctly, drive without using mobile phones, and do not drive at "turtle speed". In case of a minor traffic accident, they should withdraw quickly and compensate quickly. (Source: Dahe Daily Yu Video)
