Establishing the information display mode includes: for each type of information, determining the graphic display scheme in the display mode; for each type of information displayed, a legend is given, in which graphical examples are given for each intensity, level, threshold, magnitude, etc. of that type of information.

For weather information or other regional information, areas filled with colors or gray scales or graphs or symbols display weather influence ranges, different colors or gray scales or graphs or symbols represent different weather intensity or magnitude information, and different intensities, grades or magnitudes of the same weather;

for road attribute information, traffic information, influence information of weather on traffic and other information related to the position of a traffic line, when the information on the traffic line is relatively continuous, linear or colored lines or pattern lines such as continuous curves, broken lines, single lines, double lines and the like are adopted to represent the position of the traffic line in a two-dimensional or three-dimensional space; for the situation that the information on the traffic route is discontinuous, different color patterns or different pictographic symbols are adopted to represent the corresponding positions of the two-dimensional or three-dimensional traffic route.

For example, an embodiment that includes three types of single information display modes, in areas affected by rain, fills with color. Different colors, representing different rainfall weather intensities or levels; on a road section with influence of rainfall weather on traffic safety (traffic incident), filling the position of the road section with a color line different from the weather, wherein lines with different colors represent different degrees of influence of the weather on the traffic incident; and in the section with water accumulation tendency, marking the section position with a pictographic symbol of a water wave to indicate that the section is the section with water accumulation tendency.

As shown in figure 5 of the drawings,

according to step S100, the designated traffic route is a flight route of an aircraft in a three-dimensional space, and weather and traffic information in a three-dimensional space area where the traffic route is located is acquired.

According to step S200, the weather traffic status information determined according to the association model is three-dimensional, four types, single information, and multi-level, and includes: line attribute information (road section characteristic information on a flight line), weather information (weather type), traffic information (information on an occupied route of another aircraft), and weather influence information (influence degree of weather on flight) on the route flight.

According to step S310, a preset information display mode is established according to the contents and levels of the four kinds of information displayed. The method comprises the following steps: weather type information (including four specific weather types) is displayed by using a region filling pattern method, and a legend of the four weather types (rainfall, turbulence, icing and cloud mist) is established; a kind of line characteristic information (including four road section characteristics), display with the pictograph symbol in the position of the characteristic road section, set up four kinds of road section characteristic legends (bump road section, easy-to-freeze road section, cloudy fog road section); an illustration of the effect of weather on the flight of an aircraft on a line is established with four levels of effect (normal, light, large) using different lines to represent the degree of weather effect at the affected line or segment.

The influence of weather on traffic is marked on the flight routes, so that the flight routes marked by different line types are designated as the designated flight routes.

For example, the area where a certain color or gray scale or pattern is located represents the area affected by the corresponding influence magnitude or degree coefficient or danger level. The color or gray scale or pattern of the map itself should be significantly different from the color or gray scale or pattern that shows the weather traffic status information.

Alternatively, multiple sets of legends with significantly distinguishable features may be designed to display multiple weather messages simultaneously in the same area. The method for displaying traffic events comprises designing different pictographic symbols, and expressing a traffic factor or a certain characteristic of the traffic factor by using one pictographic symbol; pictographic symbols or symbol strings representing a certain traffic factor or a certain characteristic of the traffic factor are displayed at the corresponding traffic facility or road segment position. In addition, these pictographic symbols or symbol strings may be superimposed on traffic routes or on color curves that show the effect of weather on traffic events.

The graph represents the threshold range of rainfall values for the region in different colored regions.

And (3) displaying flood control places and flood control road sections on the railway line: and marking the pictographic symbol or symbol string representing the flood control site or the road section of the railway flood control site at the position of the flood control site or the flood control road section of the railway. Based on a GIS map, the four types of information are displayed in the area of the railway traffic line, for example, in a red coil area, the weather magnitude is light green, but the influence level of weather on water damage of each road section is whether, green, blue and yellow.

Optionally, for each of the four types of information, the number of display information may be increased, and after the number of information is increased, a preset information display mode needs to be re-established according to all the increased information contents to be displayed and the level of each type of information, and the information is displayed together based on the map. Such as: influence information of increasing the maximum wind speed for 1 hour includes: wind speed rating, area of influence, etc.; the influence information of the maximum wind speed increased by 1 hour on the railway travelling crane comprises the following steps: influence levels and wind speed threshold values and safety measures corresponding to the levels; and the position of a large air port of a railway line, the position information of a key windproof road section and the like are increased.

In addition, the precise magnitude of the four types of information can be displayed based on the position of the mouse. A mouse is hovered over or clicks on a particular line, giving a magnitude number accordingly. For a certain road section, according to the traffic weather correlation model, when the rainfall is 30.1-50.0mm/h (millimeter per hour), the influence level on the traffic safety is 2, and when the rainfall is 50.1-60.0mm/h, the influence level on the traffic safety is 3. When the rainfall is 48mm/h, the displayed content can be as follows: the influence level is 2, and the rainfall magnitude is heavy rain. When the road section needs to be specially and more finely decided, a mouse is clicked, and accurate rainfall 48mm/h and fine real-time road section information can be displayed: there is a certain risk. If the safety is needed more safely and safely according to the actual situation, the safety coping level can be improved to 3 levels, and simultaneously, the visual prompt is carried out by displaying corresponding striking colors.
