Network System

Functional system

system function

(1) Multidimensional Statistics of Accident Cases

According to the data inquiry and statistics function of the six-in-one processing platform of the Ministry of Public Security, the types of inquiry and statistics of accidents include general accidents, major accidents and general mixed accidents; the data statistics can be carried out by starting and ending time and basic constraints (number of injuries, deaths, property losses); Multidimensional accident elements are used as query conditions for data statistics; the results of query statistics will be displayed in the form of data tables and graphs.

(2) Analysis of Normalized Template

According to the specific needs of traffic police accident handling departments, the system automatically generates the normal accident research and analysis report with basically fixed content format. As the basic data analysis report of routine meetings of accident management departments, the number of various accidents in the research and evaluation cycle is analyzed by analyzing the data of road traffic accidents in the jurisdiction. The template basically covers the following aspects: the number of accident data, year-to-year and ring-to-ring ratio, etc.
The basic situation of the accident:
1.1 General accident situation of the whole province (city)
Statistical Analysis of Accidents in the Year, Half Year, Quarterly and Month
1.2 Accidents in Provinces and Municipalities
According to the administrative divisions, statistical analysis of accidents in each jurisdiction
1.3 Accidents involving more than XX deaths, in which the number of deaths can be allocated as a parameter
1.4 No death toll increased or decreased more year-on-year in detachments, brigades and squadrons

2. Characteristics of accident law:
2.1 The absolute value of road traffic accidents in XX detachment area increased year-on-year (ratio), while the absolute value of road traffic accidents in XX detachment area decreased year-on-year (ratio).
Accidents occurred frequently from 2.2 X-month to X-month, and decreased significantly from X-month to X-month.
Accident concentration from 2.3 X to X
2.4 X-section accidents occur frequently, X-section fatalities occur frequently, and the absolute value (ratio) increases (decreases) year on year.
2.5 Illegal acts 1, 2, 3... Absolute value of N rising year on year (ratio)
2.6 The absolute value of different types of vehicle accidents increased year-on-year (ratio)
2.7 Driver's driving age is within XX, and the absolute value of accident increases year on year (ratio)
2.8 Under XX mode of transportation, the absolute value of accidents increased year-on-year (ratio)

(3) Analysis of Key Research and Judgment of Road Traffic Death Accidents
In-depth mining and analysis of death accidents from multiple perspectives, the contents are shown in the annex template.

(4) Early warning warning of high-incidence tendency of traffic accidents
The system automatically analyses and locates the high incidence tendency of specific accident types, and automatically traces the analysis in successive research and judgment cycles. If it finds that this type of accident continues to be in a high incidence situation, the system will issue early warning to the traffic management decision-making department in time, so as to take timely control measures.

(5) Multidimensional Intelligent Comprehensive Research and Analysis
This paper extracts massive accident case information from the accident case database of the six-in-one platform of the Ministry of Public Security, summarizes and sums up the law of accident occurrence from several key information items contained in the accident case information by applying the theory and algorithm of big data mining analysis, locates the place where the accident occurs frequently, and presents the general text conclusion to the public. Relevant leaders and accident policemen, as a strong basis for traffic management departments to make traffic management decisions, in order to gradually reduce the probability of accidents, and to warn the trend of high accident incidence in time.

Different levels of landing users (brigades, detachments, brigades, squadrons) can conduct comprehensive evaluation and analysis of traffic occurring within their jurisdiction according to their own authority. They can conduct comprehensive evaluation and analysis without specifying any conditions. They can also conduct special evaluation and analysis of key sections, time periods or types of accidents in their jurisdiction.

Road Traffic Accident Information Collection Item

Focusing on human, vehicle, road, environment, management and other factors of road traffic accidents, the basic laws, characteristics, trends, rising points and falling points of traffic accidents in the area under our jurisdiction are found from the analysis of key drivers, key vehicles, key sections, key periods, main forms and major illegal acts. Landing point, grasp the overall road traffic safety situation in the jurisdiction, dig deeply into the underlying causes of traffic accidents, and find out the hidden dangers of traffic safety. Drivers should analyze the quasi-driving type, driving age, occupation, driving skill training, traffic safety education, driver examination and traffic violations; vehicles should be analyzed from the aspects of vehicle production enterprises, vehicle types, vehicle safety technology, illegal vehicle refitting, assembly, scrapping and vehicle use. The nature, vehicle registration, vehicle inspection and other aspects are analyzed; the road aspect should be analyzed from the aspects of road administrative grade, road type, road linearity, intersection type, sign marking, construction section, traffic safety facilities; the environment aspect should be analyzed from the aspects of time, climate, lighting, sight line, traffic flow and geographical conditions. In the aspect of management, it is necessary to manage vehicles and drivers'traffic safety sources, road design, construction, opening and maintenance, pavement order management, investigation and punishment of key illegal acts, publicity and education of traffic safety, investigation and treatment of potential traffic safety hazards, etc. in accordance with the requirements of main body responsibility, supervisory responsibility and other aspects. Surface analysis.

Examples of conclusions of research and analysis are as follows:

(6) Intelligent Expert Base Assisted Suggestion Decision-making
The system has the assistant decision-making function of the intelligent expert database. There are corresponding solutions and treatment measures in the intelligent expert database for various common types of accidents. In addition, the system also has self-learning and perfection function, which can automatically track the solutions and treatment measures taken in response to the tendency of high accident incidence. According to the next research of the system. The data obtained from the periodic analysis can be used to evaluate the measures scientifically, and the optimal weight of the measures with good effect of decision-making implementation will increase in the intelligent expert database, whereas the optimal weight will decrease for the measures with poor effect of implementation. In addition, the system can also be based on the expert advice of accident handling, according to the actual situation in the region and the whole country. The advanced management concepts of the same industry can optimize the intelligent expert decision-making database at any time, so as to make the decision-making given by the expert database more intelligent, more comprehensive and closer to reality.

(7) Decision feedback evaluation mechanism
The system automatically traces every solution and treatment measures taken for the high accident tendency. The system continues to track all the high accident tendency summarized in the previous research and judgment cycle in the next research and judgment cycle. If the high accident tendency is effectively curbed in the next research and judgment cycle, it shows that the high accident incidence is aimed at the high accident incidence. Tendency control measures are effective, otherwise they are ineffective. The system will scientifically evaluate the measures based on the improved data analysis and comparison results, and update the optimal weight of the decision-making measures in intelligent expert decision-making in real time according to the effect of decision-making implementation.
