[0041] Please refer to figure 2 , the embodiment of the present invention provides a traffic situation prediction method, the method comprising:
[0042] Step S210: Obtain the environmental data of the selected airport at the selected time and the flight volume of the airport matching the environmental data at the selected time.
[0043] The 12 domestic flight information regions are:
[0044] Northeast China: Shenyang FIR ZYSH;
[0045] North China: Beijing Flight Information Region ZBPE;
[0046] East China: Shanghai FIR ZSHA, Taipei FIR RCAA;
[0047] South Central Region: Wuhan FIR ZHWH, Guangzhou FIR ZGZU, Hong Kong FIR VHHK, Sanya FIR ZJSY;
[0048] Southwest China: Kunming FIR ZPKM, Chengdu FIR ZUUU;
[0049] Northwest China: Lanzhou FIR ZLHW, Urumqi FIR ZWUQ.
[0050] Select the airport with the largest aviation traffic in each flight information region, and obtain the environmental data of each airport, such as through the published Meteorological Terminal Avia...

[0057] Please refer to image 3 , the embodiment of the present invention provides a traffic situation prediction method, the method comprising:
[0058] Step S210: Obtain the environmental data of the selected airport at the selected time and the flight volume of the airport matching the environmental data at the selected time.
[0059] Step S222: Obtain the airport METAR message, and obtain environmental data from the METAR message, wherein the environmental data includes visibility and wind speed.
[0060] In the METAR message published on the relevant website, there are fields representing wind and visibility.
[0061] Wind: Wind is reported in 5 digits up to 99 knots and in 6 digits above 99 knots. The first 3 digits indicate the direction the wind is blowing, and if the wind direction is changing, it is reported in VRB. The last two digits indicate the number of knots of the wind speed, or 3 digits if the wind speed exceeds 99 knots. If it is a gust, then follow the ...

[0074] Please refer to Figure 4 , the embodiment of the present invention provides a traffic situation prediction method, the method comprising:
[0075] Step S210: Obtain the environmental data of the selected airport at the selected time and the flight volume of the airport matching the environmental data at the selected time.
[0076] Step S220: According to the environmental data, obtain the weather-influenced traffic weight within the selected time period, and obtain the weather-influenced traffic index of the environmental data based on the environment data, the weather-affected traffic weight, and the calculation rule of the weather-affected traffic index.
[0077] Step S232: Using the weather-influenced-traffic index as the original variable, calculate the correlation coefficient matrix of the original variable, obtain the eigenvalue according to the correlation coefficient matrix, and extract the common factors according to the principle that the eigenvalue is greate...
