Traffic is the main artery of a city and an important part of the construction of a new smart city.Intelligent road traffic management is not only a new way of urban modernization governance, but also an effective way to adhere to science and technology to police and combat effectiveness.As of Last November, the number of motor vehicles in The city exceeded 3.5 million, with more than 4.1 million drivers, ranking first in the province.In the face of the increasing number of motor vehicles and drivers, it is a test of urban governance level and innovation ability to realize “people enjoy their travel and goods enjoy their flow”.Traffic police are checking the city’s road traffic green wave coordination.(Source: Qingdao Daily) From the “big” point of view, the “14th Five-year” Comprehensive Transportation Development Plan of Qingdao “proposed to build a sustainable development of smart green transportation city.Based on the deep integration of industries, universities and research institutes and technological innovation, the Internet of Things, the Internet, cloud computing, big data analysis and other information and communication technologies are utilized to achieve more comprehensive perception, wider connectivity, more efficient collaboration and faster response at all stages of transportation planning, design, construction, operation and management.The concept of ecological protection and sustainable development will be integrated into the whole process of transport development, and we will promote the construction of a first-class and beautiful home where blue and green are closely linked and mountains, seas and cities are integrated.Start from the “small”, to “intelligent” to empower road traffic management, is the integration of the optimization of each road traffic organization, the strengthening of the standard management of each parking lot, the perfection of each piece of traffic guidance screen accurate prompt…So that people can feel more sense of gain, happiness and security in commuting, school, shopping and travel, so as to improve the quality of urban travel.In the traffic command center of the traffic police detachment of the Municipal Public Security Bureau, the staff showed the post deployment of the expressway dynamic service management system to the reporter.The screen, like a minesweeper game, is divided into grids, with flags in the middle representing the deployment of the police.The vertical section of the table is the expressway section, and the horizontal section is the time axis. Some grids are filled with red, orange and yellow, representing high-risk section, medium-risk section and low-risk section respectively.”Before, we deployed police forces based on experience in the field, but now the data speaks for itself.”Yang Jihui, deputy director of the traffic command center of the Traffic police Detachment of the Municipal Public Security Bureau, said that taking high-risk sections as an example, if a high-speed section has three traffic accidents in a year or one accident in the same period of the previous year, if either of the two meet, then the section will be judged as high-risk.”The high-risk sections may be related to the road conditions themselves, or they may be influenced by external factors such as specific weather conditions at a particular time.”Yang jihui further explained.To do a good job in road traffic management, we should not only effectively prevent traffic safety risks, but also continuously improve the ability to deal with accidents.In urban roads, traffic jams caused by small scratches are common, and the speed of accident disposal will directly affect the operation of road traffic.Qingdao traffic police, on the one hand, guided both parties to handle minor road traffic accidents quickly and independently by using the App “Traffic Management 12123”, on the other hand, adopted the flat management mode to quickly respond to police.”Taking Shinan, Shibei, Licang and High-tech Zone, which are directly under the detachment, as examples, they are divided into 50 police districts and 124 grids. Once the staff receives an accident alarm, they can directly inform the civil auxiliary police of the corresponding grid to take quick treatment at the scene.”Yang jihui said the speed of responding to police on urban roads is usually less than eight minutes.It is understood that at present, the city fully implement the road traffic safety management “double road long system” system.In area (city) government level, the total area (city) level road length, branch length and town (street), the village (community) level 4 road long long “ZongZhi road system” system, inside the public security organs, the “all the way to a long, more than a p pluripotent, alarm linkage, rapid response” level 4 “road of police” system, further clear road long responsibility at all levels, compaction compaction responsibility chain,We will continue to promote high-quality development of road traffic safety.At the same time, Qingdao traffic police have implemented the all-time and all-area intelligent police service covering the city’s urban roads, expressways, and national and provincial roads, and achieved a comparable and verifiable work effectiveness of all grass-roots traffic police squadrons and police officers to improve road control efficiency and actual combat ability.In addition, in accordance with the working principle of “normal cooperation, resource sharing, regional linkage, mutual benefit and win-win”, we took the initiative to establish and improve the integration mechanism of high-speed police cooperation in the five cities of Jiaodong with the five provincial Traffic Management teams and the high-speed detachment of Yantai, Weihai, Weifang and Rizhao, thus escorting the integrated development of Jiaodong economic circle.In 2021, Qingdao traffic police will make overall plans to deal with traffic jams and disorderly spots, carry out special studies on key areas such as transportation hubs, farmers’ markets, business districts and hospitals, and put forward and promote the implementation of comprehensive treatment.To carry out in-depth special rectification of prominent problems in parking management, continuously optimize traffic organization, accurately monitor and guide traffic flow, automatically adjust traffic signal timing, and further improve road traffic efficiency.”Taking fushun Road Vegetable and non-food wholesale market in Shibei District as an example, a parking lot is built on the top floor of the market, but some stall owners still park on the roadside to facilitate unloading, which not only forms a traffic safety hazard, but also affects the road efficiency.”Shibei traffic police introduced, in view of this stubborn disease, police to the market surrounding Tongyu road as a pilot, on both sides of the road to draw a yellow stop line, to remind drivers to stop, and through video monitoring to park more than two minutes of vehicles for automatic capture.At the same time, based on the periodic single point optimization of multi-target radar, through collecting and analyzing the traffic flow data of the intersection of Shandong Road fushun Road, the corresponding intersection signal scheme is calculated.After the implementation of the optimization scheme, the green loss time of the intersection is reduced by 71.9%, the traffic efficiency is increased by 7%, and the corresponding green loss time of the average cycle of flat peak is less than 1 second.In addition, the Qingdao traffic police will also school surrounding traffic regulation as a crucial point, using big data analysis, “a school policy, adjust measures to local conditions puts forward the mistake ShangFangXue, set the transport channel, vehicle parking time limit or stop or go, developing new ShangFangXue busing students, campus police” home “joint to carry out the series of measures such as traffic safety.According to reports, in 2021, Qingdao traffic police combined with the people’s livelihood police hotline to reflect the problem, scientific analysis of the city’s old urban areas, schools, hospitals and other 83 hot spots prone to congestion, targeted to determine 109 key control roads, 18 key commercial blocks and construction sections of the implementation of fine traffic organization.The report of 122 congestion around 87 primary and secondary schools dropped by 6.6%.Fine traffic organization has been carried out on more than 160 roads and 600 intersections, and “micro-circulation” traffic flow has been adjusted in 162 old open residential areas.At the same time, the potential parking resources are explored in depth, the in-road berths are continuously optimized, and 35,000 shared berths and off-road berths are added.”Point, line, face” comprehensive ShiCe, increase the efficiency of the management at present, the city has established “the traffic organization optimization and combined closely with the traffic signal tuning” mode of specialization, founded “strategy recommendation, scheme automatically generated automatically, and automatically optimize effects” of intelligent signal control mechanism, formed in covering more than 1000 city intersection traffic signal timing intelligent optimization system.”We are now improving governance effectiveness through ‘point, line and plane’ control strategies.”Cheng Hao deputy director of the municipal public security bureau traffic police detachment traffic command center, shandong road sections of the road, for example, using big data analysis, in the shandong yenji road intersection to implement variable lane, lane tidal, when area comprehensive traffic organization optimization measures, such as overall traffic intersection efficiency increased by 11.47%, late peak of shandong lunan imported vehicle queue dissipation time shortened 20 minutes;After the implementation of the control of main and auxiliary roads at the intersection of Shandong Road and Dunhua Road, the traffic capacity at the east and west entrances of Dunhua Road is improved, the traffic efficiency at the intersection peak hour is increased by 10.21%, and the length of queue on the bridge is shortened by 42%.Let travel more “wisdom”, but also reflected in all aspects of traffic management work.At present, Qingdao is also accelerating the construction of the project of “one parking lot in the whole city”, coordinating and integrating parking resources in the whole city, realizing real-time intelligent induction and shared use, and striving to create a new pattern of “one parking network” in Qingdao city.”From information to intelligence to intelligence, ‘science and technology to police’ on the one hand is to solve the current situation of insufficient police on the road, on the other hand is to make good use of the power of science and technology in hand, with a more accurate and efficient way to do a good job in traffic management.”City public security Bureau traffic police detachment deputy detachment leader Yan Bing said.With the development of The Times, people pay more and more attention to the smooth feeling and comfort in the process of travel.In the face of the increasing number of motor vehicles and the limited space of urban roads, how to solve the problem of traffic congestion and other “urban diseases” is a test of a city’s governance level and management ability.With the continuous iteration and application of all kinds of information technology, digitalization has become an important means to improve the ability of urban governance.As one of the most widely used scenarios of smart city, intelligent transportation carries people’s expectation for future transportation.At present, Qingdao’s traffic management work is changing from passive problem solving to active prediction, guidance and precise policy making.But this is only a small step towards smart transport.In the future, how to maximize the use of urban road resources, effectively reduce traffic congestion, and timely provide travel services requires more “smart” forces, more application scenarios, more responses to “soft demand” and forward-looking layout.Qingdao Daily/Sea
