Service guarantee three "No. 1 projects".
Accident handling, violation crackdown, epidemic prevention and control, command and dispatch ......From the road traffic police squadron to the epidemic prevention and control class, and then to the traffic police command center, the post rotation honed his ability to dedicate himself to public security, and the role change strengthened his determination to serve the people. Since joining the police, he has always remembered the glory and mission of the police uniform with a high sense of responsibility, and has written his unique navy blue story in an ordinary post.
Digital intelligence green wave, digital economy innovation for the people
The "line" in clothing, food, housing and transportation is the link between the people and the traffic policeThe "wait at most" green wave construction project, which is included in the evaluation system for optimizing the business environment, is an important part of the three "No. 1 projects" for high-quality development. Zheng Yuli's ** Police Command Center, focusing on the "pro-police" and "pro-police" work goal, uses the method of "building a green wave belt and improving traffic efficiency" to contribute its energy to the traffic management bureau's commitment to "safe, convenient and smooth", and reduce the burden on society, enterprises and the masses for smooth travel.
The construction of green wave belt is a multi-point control technology of signal lights that integrates signal control, traffic organization, data analysis and other disciplines, which can realize that when the driver drives at a given speed on the road section, he can pass through multiple intersections without stopping or stopping, and the traffic experience is better.
After Zheng Yu arrived at the command center, he conscientiously learned relevant knowledge from leaders and experts, integrated his own expertise, and refined the "Green Wave Four Threes" working method, namely "three-wheel drive, three-dimensional analysis, three types of programs, and three evaluations", and controlled the congestion with "numbers", and has built 57 green wave belt roads in Wenzhou City, covering 438 intersections, with a total mileage of 14908 km, compared with before the construction, the road traffic speed increased by 147%, which equates to 147% of the time, widely acclaimed;The effectiveness of our city's green wave control and congestion was recommended as a typical scenario of public data authorization operation practice in Zhejiang Province at the 2nd Global Digital ** Expo, and the "Green Wave Belt" construction project has begun to take shape as a "sweet potato economy".
Keep an eye on traffic and keep an eye on road conditions
In October this year, Zheng Yu found through daily observation and patrol that the traffic around commercial entities such as Wutian Old Street and New Farmers' Market in Wutian Area of Ouhai was large, the occupancy rate of real estate around Yuele Street increased, and the traffic flow of Yuele Street increased, resulting in frequent congestion at the intersection of Yuele East Street on Huimin Road.
After observation and analysis, it is preliminarily judged that the reasons for the congestion at the intersection are: first, the morning rush hour commute traffic flow is superimposed on the return traffic flow of the farmers' market, and the left turn at the west exit is saturated, resulting in congestion when entering Huimin Road;Second, there is only one left-turn lane at the west exit, and the traffic efficiency of U-turn vehicles is low, which further amplifies the congestion. The original signal control scheme, in order to ensure the basic traffic time of the east and west entrances, the optimization space of the north-south signal control scheme is extremely limited, and Huimin Road, as an important passage connecting the city ** and Ouhai Avenue elevated, has not been able to land its green wave construction.
Zheng Yu and the leaders and colleagues of the command center carefully studied, together with the order brigade and the squadron under the jurisdiction, formulated an optimization plan for "adding a new left turn lane and changing the right turn lane to a straight right lane" at the west exit of the intersection of Yuele East Street, Huimin Road, to ensure that the efficiency of east-west straight traffic is basically unchanged, and at the same time, the effect of "reducing the left turn time and improving the actual efficiency" of the west exit is realized.
Build a model to form a closed loop of evaluation and optimization
The construction of the green wave belt is a systematic work with precision, timeliness and spatiotemporal at the same time, and how to scientifically quantify its effectiveness according to dimensions is a topic that needs to be solved urgently.
Under the guidance of the leaders of the command center, Zheng Yu innovatively integrated the basic indicators such as vehicle speed, parking times, queuing length, and traffic time through mathematical formulas to form three indexes: smooth traffic index, vehicle parking index, and Gaode index, and constructed a green wave belt effect evaluation model to quantitatively evaluate the overall effect of the green wave road section according to four grades: excellent, good, pass, and fail. After the model was put into practice, the green wave stock in the urban area was optimized, and the effect of 31 green wave bands was successfully optimized.
The model also represented the Wenzhou Municipal Traffic Management Bureau and participated in the modeling competition organized by the Provincial Traffic Management Bureau and won the third prizeIt was selected as an excellent model by the Provincial Traffic Management Bureau, and recommended to participate in the preliminary round of the National Modeling Competition organized by the Traffic Management Bureau of the Ministry of Public Security.
Since Zheng Yu joined the police, he has been praised by the Municipal ** and Municipal Public Security Bureaus many times, received personal commendations three times, and made personal third-class merits once. With the pride of the people's police, he personally practiced the work belief of "holding the responsibility in hand and shouldering the responsibility". "The people's police are the light of a city, and they must shine into everyone's heart," he believes, and has been working towards this goal.
