On October 28, the traffic police detachment of Nanchong City, Sichuan Province, invited the mainstream media of the central provinces and cities to experience the coordination effect of the green wave of 21 main roads in the city, and released the operation of the intelligent traffic signal control center. Liu Hongguo, member of the Party Committee of the Nanchong Municipal Public Security Bureau and head of the Municipal Traffic Police Detachment, Xiong Bing, deputy head of the detachment, and the heads of the Publicity Network Section, the Traffic Order Section and the directly subordinate brigades participated in the experience and attended the press conference.
Liu Hongguo led the team to Baituba Road, Yudai Road, Binjiang South Road, Jiangdong Avenue, Dongshun Road, Huandu Avenue, North Trunk Road and other urban main roads to investigate and experience the coordination effect of green waves. During the experience, the author found that after the installation of the Green Wave Belt, the entire yudai road was 3.6 kilometers, and the traffic time before optimization was 9 minutes and 23 seconds, and after optimization, it was 5 minutes and 17 seconds, and the traffic time was reduced by about 45%. The entire section of Binjiang South Road is 2.1km, the traffic time before optimization is 5 minutes and 30 seconds, and after optimization, it is 2 minutes and 35 seconds, the traffic time is reduced by about 53%, the number of stops is reduced from 3 to 0, and the average speed is increased from 45km/h to 60km/h. According to reports, at present, Nanchong City has completed the implementation of two-way green wave belt coordination control on 21 main roads such as Yudai Road, Binjiang Road, Duwei Road, Jiangdong Avenue, Mashi paving road, Huandu Avenue, and Xihe South Road.
Subsequently, everyone returned to the intelligent traffic signal control center of the municipal traffic police detachment to visit and understand. As the operating unit of the center, Hu Gang, the person in charge of the southwest area, introduced the functional positioning, construction objectives, operation mode, work module and preliminary results of the control center to everyone.
According to reports, the traffic signal control center takes signal timing optimization as the core, covering a series of work related to urban road congestion mitigation and smoothness, such as traffic signal optimization, traffic operation evaluation, big data analysis, traffic public opinion processing, etc.; positioned as the "brain" and core management agency of urban traffic congestion, there are four functional positioning such as traffic signal operation management agency, traffic signal control technology research center, multi-source traffic data processing and application center, and traffic optimization multi-department coordination agency.
At the press conference, Liu Hongguo pointed out that in order to improve the quality of citizens' travel, improve the efficiency of traffic, ensure urban traffic safety and gradually realize the wisdom, intelligence and efficiency of management, and realize the unified management, fine control and professional protection of urban traffic signals. The Nanchong Municipal Party Committee and Municipal Government and the Municipal Public Security Bureau attach great importance to and vigorously promote the intelligent, professional and refined development of transportation. In accordance with the spirit of the "Guiding Opinions on Further Strengthening the Application of Urban Road Traffic Signal Control" issued by the Traffic Management Bureau of the Ministry of Public Security, through extensive consultation in the industry and drawing on the experience of advanced cities in China, the Municipal Traffic Police Detachment introduced a professional team for traffic signal control in the form of public bidding in April this year, and jointly established the first "smart traffic signal control center" in the province.
At present, the city's "smart traffic signal control center" has achieved certain results in the main urban area to alleviate congestion and ensure smooth work, but there are still some problems and shortcomings in the actual work, but there are still urban signal lights that have not yet reached full coverage, and the overall effect is not obvious; the signal lights are not uniform in planning, construction and management, and nearly 200 signal machines cannot achieve networked joint control due to hardware functions; the distribution of lanes is unreasonable, the marking lines are not perfect, and the traffic light settings are not standardized In a few places, there are still unreasonable regional traffic organizations, mismatched traffic flow and road carrying capacity, and the deep-seated problems that restrict the in-depth promotion of traffic management work, such as congestion, cannot be completely solved through the optimization of signal lights. Liu Hongguo introduced.
In the next step, the municipal detachment will continue to expand the scope of signal light service intersections, gradually replace signal machines that do not meet the specifications, realize the networked joint control of all urban signal lights, further enhance the refined intelligence level of urban road traffic signal control applications, and continuously improve the traffic signal control application management work mechanism. At the same time, based on the characteristics of local traffic laws, in-depth study of commercial concentration areas, regional connection roads, important bridges and tunnels, key intersections and other key areas prone to congestion, scientifically formulate the overall strategy of congestion control, to alleviate congestion in urban areas to the greatest extent, and create a safe, orderly, smooth and civilized road traffic environment for the people to travel.
It is reported that the number of motor vehicles in the three districts under the jurisdiction of Nanchong City has reached more than 450,000, more than 700,000 motor vehicle drivers, and there are 357 groups of traffic lights in the urban area. Since the operation of the "Smart Traffic Signal Control Center", 155 networked joint control signal light intersections have been optimized, and the timing of signal lights at 216 important intersections has been optimized, and green wave coordinated control has been implemented on 21 main roads in the urban area. Combined with the analysis of the third-party big data platform, it is learned that the traffic congestion index in the main urban area has dropped by 3.8% compared with the same period last year, the average road traffic time has dropped by 27.3%, the delay index has decreased by 23.8%, the average daily peak congestion time has been shortened by about 20 minutes, and the average speed of the road implementing green wave coordinated control has increased by about 14.5%.
Since the beginning of this year, the city's public security traffic police department has focused on the goal of "safe traffic and smooth Nanchong" and has gone all out to grasp various traffic management work. In terms of accident prevention, we will continue to deepen the six major improvement actions of "reducing the amount and controlling the large", the number of traffic accident deaths will drop by 15.17%, the accident of 2 people will drop by 30%, and the "zero occurrence" of larger accidents will drop by 100%. In terms of special operations, a total of 4632 cases of drunk driving, 824 cases of drunk driving, 6201 cases of overloading of trucks, 2730 cases of overcrowding of passenger cars, and 3623 cases of speeding of passenger cars were investigated and punished. In terms of vehicle management services, the Ministry of Public Security's "I do practical things for the masses" public security traffic management 12 facilitation measures, the implementation of Nanchong public security traffic management "I do practical things for the masses" 6 measures, the completion and operation of the province's first 24-hour intelligent vehicle management service hall and 11 city and county vehicle management offices 11 "No. 1 window".
At the same time, combined with the actual situation, by creating the operation and management mode of "1 centralized operation + 5 management elements + N support service platforms", the intelligent, refined and professional level of urban road traffic signal control applications in Nanchong will be further improved, so as to escort the safe and smooth travel of the general public.
At the press conference, the leaders of the Municipal Traffic Police Detachment and the directly subordinate brigades at all levels interacted with the news media present and answered the questions of the media in detail. (Editor-in-charge: Peng Jianqiang)
