Embodiment Construction

[0031] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0032] Such as figure 1 As shown, the present invention discloses a calculation method of airway network node space-time flow, the specific steps are as follows:

[0033] Step 1) Obtain the radar data of the airspace where the route network node to be evaluated is located, and transfer the radar track of this airspace into a computer-readable file (.txt).

[0034] First, use the "Domestic Aviation Data Collection" manual to visit the regional control centers, approach control rooms, and tower control rooms of various airspace control activities across the country to collect data, and use C# language development on the GIS (Geographic Information System, geographic information system) platform TransCAD traffic simulation software, the traffic simulation software can realize various models and algorithms, and establish the evaluation index set and e...

Abstract

The invention discloses a calculating method of space-time flow of air route network nodes. The method comprises the steps that firstly, M-year radar data of airspace where the air route network nodes to be assessed are located are obtained, and specific information of an aircraft is analyzed; secondly, the traffic volume of time frames of the air route network nodes to be assessed in M years is determined, singular values are removed, and a function relation between the annual traffic volume and the number of flights passing in each time frame of the air route network nodes to be assessed is determined in a fitting mode; thirdly, OD flow in many years of main airports in the whole country is obtained, OD requirements of the main airports, needing to be forecast, in the whole country in the year are forecast, and annular traffic volume of the air route network nodes to be assessed is calculated in the year needing forecast ; finally, traffic volume distribution of each time frame of the air route network nodes to be assessed in the year needing forecast is calculated. The calculating method provides data support for forecast of flow of each time frame, flight conflict can be handled in advance, a traffic jam is reduced, the air route network using rate is increased, and the work amount of a controller is reduced.

Description

technical field [0001] The invention relates to the field of forecasting air traffic volume of airway network nodes, in particular to a calculation method for time-space flow of airway network nodes. Background technique [0002] The OD volume of air traffic at the originating and destination airports refers to the traffic volume between the originating and destination airports; the airway network node refers to the airway intersection, which is the intermediate node connecting the originating and destination airports in the airway network, and is also the transmission point of flight flow, which neither generates The flow does not absorb the flow, and the spatial position of the route network nodes can be designed, which has the functions of improving the utilization rate of the route, avoiding the cross-border route, and reducing the control load. [0003] With the development of civil aviation and the increase in the number of aircraft, it is easy to cause congestion on f...
