Since the installation and use of the "Zhixing Zibo" mobile phone app, Mr. Li, a citizen of the unit in Boshan and the house in Zhangdian, saved the time to get back and forth for more than half an hour. "There are intuitive voice broadcasts and image display in the app, providing road traffic prediction, speed guidance, green wave pass service, and the driving process is a lot easier."

This will benefit from the traffic police detachment of the Zibo Public Security Bureau to seize the construction opportunities of Zibo City's "Shuangzhi City", actively apply the Internet of Things, cloud computing, mobile Internet and other technologies, and take the lead in the "car road collaboration" smart transportation system nationwide. Relying on science and technology empowerment and quality services, promote urban transportation to break the "blocked" "excellent", allow drivers to "all the way green lights", improve traffic efficiency, and reduce carbon emissions.

At present, the city has realized the "vehicle and road collaboration" application scenarios at 967 light control intersections in 9 districts and counties. Boshan District has become the nation's first Internet of Things cloud control signal machine test application demonstration area. The "car and road collaboration" smart transportation system won the first prize of "Smart Public Security and Me" in the province's grass -roots technological innovation and competition contest finals.

As of late September, the system users reached 100,000. Since the system is running, the pilot optimization of the signal lights of the intersection has been greatly improved. After testing by Nankai University, the average vehicle speed increased by 28%, the traffic time was reduced by 27%, the average fuel consumption decreased by 24%, the carbon emissions decreased by 23%, and the travel cost was greatly reduced.

"Green Light Free"

At 7 o'clock in the morning, at the peak of the morning at work, the road was carried on the road in Boshan City.

"3 signal light intersections on the eastern section of the Boshan Central Road, 660 meters section, the previous traffic time is about 1 minute and 28 seconds. After setting up green waves, the traffic time is about 45 seconds, and the traffic efficiency is about 50%." Introduction.

What is green wave? "Adjust the parameters such as the signal light cycle, phase phase sequence and green letter ratio of each intersection. On the specified road, when the vehicle encounters green lights when the vehicle passes through the first cross port, drives at a certain speed, it is adjacent to the same speed. Several intersections can continue to encounter green lights to ensure smooth traffic. "Gaomingyong explained that reasonable" green waves "settings can not only enhance the linkage between road sections and sections, but also improve the quality and efficiency of the entire area.

At 11 o'clock, the traffic flow from the south to north from the south to north of the Boshan Longquan Street became a long dragon, and there was a short period of traffic jam. Li Chuanwu, the head of the traffic management department of the Boshan Traffic Police Brigade, took out his mobile phone. In the "vehicle and road collaboration" smart transportation system, the signal of the north -south phase of the intersection broke the "blocked" and "excellent", and the problem of vehicle congestion quickly relieved.

Through the Boshan Magong Temple tunnel, the National Highway 205 has a long and steep mountain road. A set of road lamp bands are installed here. The "car road collaboration" smart transportation system projected the traffic signal lights to the road in the form of road side lights. The driver only needs to observe the indicator light to enter and keep it in the green light range to pass the green wave. In the signal lighting area, the truck Liang gradually slowed down.

The east section of Boshan Central Road has achieved two -way green waves. "The Internet of Things cloud control signal machine system uses GPS+Beidou connected connected control to make the time benchmark of the Internet of Things cloud control signal consistent, and it plays a major guarantee for the realization of road green waves." Introduction to the Internet of Things cloud control signal machine.

"The" IoT Cloud Control "signal machines with vehicle road collaboration functions are installed in 64 light control intersections in Boshan District, becoming the first Internet of Things signal machine test application zone in the country." Gao Mingdong introduced, "car road collaboration" Through the "Internet of Things+Mobile Internet" technology, the smart transportation system opens up the link between people, cars, roads, and traffic signals, and implements the integrated operation of "sensory -joint -calculation -control" to effectively improve road traffic capacity.

The "green light freedom" described by everyone on the driving road has become a reality step by step under the guidance of the "car and road collaboration" smart transportation system.

Computing power empowerment

"Please help us!" Among the crowded traffic flow, a driving crowd suddenly asked the police for help, saying that there was a wounded in the car. The three fingers were mechanically hit and lost their consciousness.

Boshan Traffic Police uses the "car road collaboration" smart transportation system to open the "one -button green wave" and "one -button special service" function to open up a green life channel for the wounded. The original 40 -minute journey only delivered the patients to the patients. Patient's treatment has won valuable time.

"Controlled the entire line, the entire process of automation is not sensitive" is an important part of the "car road collaboration" smart transportation system. "Through the implementation of 'feel -couplet -calculation -control' integrated operation, when performing emergency rescue, rescue disaster relief, emergency repair and other tasks, create special service tasks through vehicle special service terminals or consoles. Information such as the end, passing the intersection, the number of vehicles (or the time for the guarantee of the signal lights and green lights), and the system will automatically complete the entire process operation of the intersection, the emergency vehicle pass, and the normal state of the normal state according to the speed of the special vehicle and the time of the intersection. To maximize the time to reduce traffic and reduce the impact on social transportation. "Wang Yongfeng, head of the facility brigade of the Traffic Police Division of the Municipal Public Security Bureau.

Smart transportation is an important part of high -quality people's livelihood. The "vehicle and road collaboration" smart transportation system is the intelligent digital infrastructure that is based on the integration of pan -access, network integration, and interconnection. The situation of road conditions automatically perceives and the traffic control dynamic adjustment has been automatically improved to effectively improve road traffic. "'Car Road Collaboration' Smart Transportation System through the installation of the Internet of Things signal machine, traffic signal data collector, to connect people, vehicles, roads, and traffic signal links. During the period of time, the speed interval of the intersection, through the "Zhixing Zibo 'mobile app voice broadcast and image display, to provide drivers with road traffic prediction, speed guidance, and green waves." Wang Yongfeng told reporters.

At the same time, with the Gaode Map as the base, relying on the "Zhixing Zibo" mobile phone app, real -time display of road traffic situation in the front of the front, the opening of the road congestion, unblocked, etc., to facilitate the driver to adjust and optimize the route in time Digital level. Focus on the smooth and balanced overall traffic and the rapid traffic of the urban arteries, accurately configure the relevant road sections and green waves at different times, determine the intersection of the starting point and end point of the road, set the signal cycle, the green wave duration, and the speed of the vehicle to achieve the one -click section of the IoT signal control section. Two -way green waves, minimize traffic delays. And focusing on solving the problem of saturation of the traffic at the peak of traffic, the police on duty should be used to remotely adjust the signal of the intersection through handheld control terminals to alleviate the problem of vehicle congestion.

"At present, the" car road collaboration "application scenario has been realized at 967 light control intersections in 9 districts and counties. 77 groups of road side light bands were installed in 5 sections of the city." Wang Yongfeng told reporters that "car road collaboration" smart transportation system Each traffic light is built into a bridge of numbers, smoothness, and convenient services.

As a traffic manager, in Wang Yongfeng's view, the progress brought by the "car road collaboration" smart transportation system will be revolutionary. In this system, the links between people, cars, traffic lights, and roads are completely opened, and each of them will become participants of the smart transportation system. Relying on the computing power, the new productivity of information computing power, data storage power, and network carrier capacity, for different data elements such as vehicle speed, location, and signal lights, concentrated algorithm processing to allow the vehicle to automatically group formation during the journey process. , To automatically generate a safe traffic solution that is adapted and actively controlled by car roads, it will effectively promote traffic management methods from traditional "human -type, experience, passive" to "human -computer interaction, data -driven, active disposal" transformation "transition" transition "transformation" transition " Essence

Perspective

At 6 pm, the new Mart road section of Zhongrun Avenue, traffic is like a tide, and people are like weaving.

"The pedestrian security guarding system on this section is being debugged in the tightness. When the system will coordinate the signal lights of the upstream and downstream intersections, the system will clarify the pedestrian, vehicle pass and the timing of the pass, avoid the conflict between pedestrians and vehicles, reduce the hidden dangers of traffic accidents, and improve in all aspects. Pass efficiency. "The relevant person in charge of the Traffic Police Division of the Municipal Public Security Bureau introduced.

The "car and road collaboration" smart transportation system is a systematic project, and the construction process has faced many problems.

Once, there were 19 brands in Zibo City's 1435 signal lamp intersections. The control system was messy and data could not be shared.

"The Traffic Police Division of the Municipal Public Security Bureau strengthened its thinking, installed the data collector of the signal machine, and set up a third -party control platform to run the operation data of different brands, different models, non -network signal machines, network signal machines, and alarm information ( The power outage, yellow flash, lack of phase, etc.) were included in the platform management, and realized centralized control 'one platform', unified management 'a network'. "Sun Jingshuang, secretary of the Party Committee and Division of the Traffic Police Division of the Municipal Public Security Bureau.

At the same time, independently developed the country's first Internet of Things cloud control signal machine, gathered integrated traffic signal data, and achieved facilities networking control and signal intelligent adjustment. The cost of signal machine construction was only 10%of the previous brand signal machines. Breakthrough.

The ultimate goal of scientific and technological innovation is to benefit the people, benefit the people, the people, and the people. In the construction and application of the "car road collaboration" smart transportation system, it has taken the initiative to shift from "government thinking" to "mass perspective" and "development position" to "user experience" to become a significant highlight.

"Farewell to congestion and having a better driving experience is the urgent needs of the general public. Green lights', enjoy the joy of acting, improve the efficiency and reduce carbon emissions. "

It is understood that on the basis of the "car road collaboration" application scenarios in 967 light control intersections in 9 districts and counties in the city, a full -coverage of the "car road collaboration" city has launched.
