[0051] like Figure 1As shown, in this embodiment, a regional flow saturation and imbalance event hierarchical warning and emergency disposal system is provided, including: a monitoring area management module, an event hierarchical warning module, an event comprehensive verification module, an event emergency plan module, an event sign-off control module, and a control effect evaluation module;

[0052] The monitoring area management module is used to obtain the early warning area where traffic needs to be monitored;

[0055] The event emergency plan module is used to formulate police traffic control measures and road traffic emergency support plans according to the type and level of the confirmed real event;

[0058] Furthermore, the event classification warning module includes an event classification unit and an event classification unit;

[0059] The event classification unit is used to classify the warning area to obtain flow saturation events and flow imbalance events;

[0060] The event classification unit is used to classify the flow saturation event and the flow imbalance event to obtain a classification result.

[0061] Specifically, based on the frequent types of cross-regional traffic incidents, regional sudden traffic incidents are divided into regional traffic saturation and traffic imbalance incidents, and each type of incident corresponds to a corresponding classification basis according to its characteristics.

[0062] A regional traffic saturation event refers to a real-time monitoring of the traffic flow and traffic operating environment of the designated regional road network, the dynamic calculation of the saturation level of the regional road network traffic, the acquisition of the real-time traffic saturation value of the regional road network based on the calculation of the regional road network traffic saturation level, the classification of the traffic saturation level, and the formation of a regional road network traffic saturation event.

[0063] A regional traffic imbalance event refers to real-time monitoring of the traffic saturation level of each road in a designated area, establishing a regional road network traffic imbalance coefficient, and evaluating the balanced distribution of traffic within the road network. When a traffic imbalance is detected on roads within the region, a traffic imbalance event is generated.

[0064] Further, the event classification unit includes a flow saturation event classification subunit and a flow imbalance event classification subunit;

[0065] The flow saturation event classification subunit is used to calculate the regional road network capacity, the regional road network saturation and the saturation of the road network capacity for the flow saturation event, and classify the flow saturation event based on the regional road network capacity and the regional road network saturation;

[0066] The flow imbalance event classification subunit is used to calculate a flow imbalance coefficient for the flow imbalance event, and classify the flow imbalance event based on the flow imbalance coefficient.

[0067] Specifically, based on the basic information such as the location of the incident, road grade, duration, etc., the incident impact level is divided into four levels based on the scope of impact, severity, attribute information, etc. Each type of regional traffic incident is divided into four levels: level 4, level 3, level 2, and level 1, representing general, relatively serious, serious, and extremely serious, respectively.

[0068] Furthermore, grading the traffic saturation event based on the regional road network capacity, the regional road network saturation and the saturation of the road network capacity includes:

[0069] The calculated regional road network capacity is:

[0070] C i =Road theoretical capacity*f,

[0071]

[0072] Among them, C represents the actual capacity of each route in the regional road network, C i It represents the actual capacity of a certain route in the regional road network, and f represents the correction coefficient of theoretical capacity.

[0078] The calculation area road network saturation is:

[0079]

[0080] Among them, F represents the regional road network flow saturation, V represents the traffic flow in and out of the monitoring area, and V i Represents the traffic flow in and out of a certain section of the monitoring area.

[0081] The regional road network saturation is calculated based on traffic congestion data:

[0082]

[0083] S(d)=∑(W i *d i )

[0084]

[0085] Among them, F represents the regional road network flow saturation, S(d) represents the congestion mileage, S(z) represents the total mileage of the road network, and W i represents the normalized congestion mileage weight, d i Represents the total mileage corresponding to a certain congestion level on a certain road section, x i Represents the congestion mileage weight.

[0086] Congestion mileage weight x i The values ​​are shown in Table 2 below:

[0087] Table 2

[0088]

[0089] Specifically, according to the above flow saturation (F) calculation results, the flow saturation events are classified as follows: (1) Level 4 flow saturation event: F < 0.4;

[0090] (2) Level 3 flow saturation event: 0.4≤F<0.6;

[0091] (3) Secondary flow saturation event: 0.6≤F<0.8;

[0092] (4) Primary flow saturation event: F ≥ 0.8.

[0093] Further, grading the flow imbalance event based on the flow imbalance coefficient includes: calculating the flow imbalance coefficient based on the flow data as:

[0094]

[0095] Where E represents the flow imbalance coefficient, Fi represents the saturation of road i, Fj represents the saturation of road j, and Fi≤Fj.

[0096] Specifically, according to the above flow imbalance coefficient (E) calculation results, the flow imbalance event classification is as follows:

[0097] (1) Level 4 flow imbalance event: E ≥ 0.8;

[0098] (2) Level 3 flow imbalance event: 0.6≤E<0.8;

[0099] (3) Secondary flow imbalance event: 0.4≤E<0.6;

[0100] (4) Level 1 flow imbalance event: E<0.4.

[0101] The regional emergency traffic incident comprehensive verification module focuses on key monitoring areas, especially provincial key sections, highways, toll stations, service areas and other areas that are prone to cross-regional large-scale congestion, gathers traffic incident information from all parties in the region, and comprehensively verifies the authenticity and severity of regional emergency traffic incidents such as regional traffic saturation and traffic imbalance. The flow chart is as follows Figure 2 shown.

[0102] The sources of regional traffic incident information include:

[0103] 1. Accidents, construction, road subsidence and other unexpected traffic incidents discovered by expressway section operating companies through reports, inspections, etc.;

[0105] 3. Traffic emergencies collected proactively by local traffic management departments through police response, video inspections, road inspections, etc.;

[0106] 4. Detect and identify sudden traffic incidents in the area through AI methods such as big data analysis of collisions and traffic changes;

[0107] 5. Severe weather warnings such as heavy rain, strong winds, heavy fog, heavy snow, slippery roads, icy roads, etc. issued by local meteorological departments;

[0108] 6. Road traffic incidents actively reported by users of Baidu, Amap, and Tencent Maps through map apps while navigating.

[0109] Through the comprehensive verification module, invalid and repeated events are filtered out, and regional event safety risks are classified and graded according to the four-level severity classification method. An AI analysis model is established, and the model structure is shown in Table 3 below. Comprehensive verification and analysis are performed based on road network basic information, road network operation data, weather data, road operation video images and other data. Through big data calculation, the verification results of the reported events are given, that is, the event type, impact level and event confidence after event verification.

[0120] Specifically, the regional emergency traffic incident acceptance control module will accept and process the relevant local traffic police units according to the scope of the regional traffic saturation and imbalance events. In combination with the actual road conditions, traffic police control measures are implemented and issued. In terms of specific means, this module can take three types of measures, including warning prompts, traffic guidance, and traffic control, and formulate and issue multi-strategy control measures such as remote warning prompts, mid-end route guidance, and near-end traffic control.
