Definitions
- the present invention relates to the determination of the complexity of handling air traffic control situations on sectors by operators, for example air traffic controllers.
- the present invention also relates to the definition of air sectors, and the assignment of these sectors to operators.
- air traffic control systems The purpose of air traffic control systems is to make the execution of flights safer, faster and more efficient. They make it possible to prevent collisions between aircraft, or dangerous situations between an aircraft and its environment (weather, terrain, etc.). They thus make it possible, by synchronizing as finely as possible the movement of aircraft, to ensure safe air traffic, but also allow aircraft to respect the scheduled flight times, and to adopt trajectories as economical as possible. possible in fuel.
- air traffic controllers receive a set of information relating to the airspace: position and predicted trajectories of aircraft, the weather, etc.
- the controllers can also communicate, via written messages or oral communications, with the pilots of the aircraft in order to retrieve additional information, if necessary, and give them instructions adapted to the situation, to guarantee the safety of air traffic, while ensuring the best possible quality of service for transport users air.
- air traffic controllers can communicate to pilots the opportune moment to land or take off from an airport, or conversely instruct them to defer their approach if an airstrip is used by aircraft on time initially. planned.
- the quality of the work of air traffic controllers is therefore essential, to guarantee both the safety and the efficiency of air traffic.
- the work of air traffic controllers is organized by geographic sectors.
- the complexity of the work to be done in an area varies depending on a number of factors, the most important of which is the complexity of the traffic: an air traffic controller will only be able to efficiently handle a limited number of flights simultaneously.
- a varying number of controllers can be assigned to each sector, so that each controller only deals with a situation of sufficiently low complexity (for example, involving a number of flights, limited trajectory conflicts, where applicable in relation to environmental characteristics such as the weather for example) to perform the job properly.
- July 2018 defines analytical functions to calculate an index of ATC complexity on an air sector according to a set of indicators impacting the complexity of handling an air situation: number of aerodrome, area of a sector, number of surrounding sectors, number of altitudes used, average speed of aircraft, number of incoming flights, number of outgoing flights, number of conflicting aircraft, average convergence angle for conflicts, traffic density, etc. These indicators can be combined within complex functions.
- the definition of analytical functions of complexity has given rise to numerous publications such as Laudeman, IV, Shelden, SG, Branstrom, R., & Brasil, CL (1998). Dynamic density: An air traffic management metric, Netjasov, F., Janic, M., & Tosic, V. (2011).
- analytical functions have several disadvantages.
- analytical functions are extremely complex, and their execution time varies depending on input parameters, including the number and complexity of aircraft paths over a sector. For particularly large sectors, the computation time can thus become very long, of the order of several seconds.
- the analytical functions calculated on CPU thus do not guarantee a fixed and low response time for the evaluation of the complexity of a sector. In the case of complex sectors, they do not guarantee a sufficiently low execution time to dynamically assign controllers according to the evolution of air traffic.
- the invention relates to a computer-implemented method comprising: obtaining an ATC situation defined by a sector and a period of time, and a set of input parameters comprising, for the sector and the period of time, the trajectories of aircraft crossing the sector, said trajectories being defined by a set of trajectory parameters comprising at least the positions of the aircraft; the calculation, for each of the aircraft trajectories, of trajectory parameters at a set of identical time steps for all the trajectories; the formation of a matrix comprising, for each possible pair of trajectories, the parameters of the trajectories of the couple at said time steps; the application to said matrices of a transformation having the property of concentrating energy by component; the calculation of energy by component; calculating a complexity index of the ATC situation, based on a level of energy concentration by component.
- said calculation, for each of the aircraft trajectories, of the positions of the aircraft at the set of time steps consists in interpolating the positions of the aircraft on the trajectories.
- each row of the matrix represents a pair of trajectories; the columns of the matrix represent respectively, in successive time steps, the values of each of the parameters of the trajectories, for the first and then for the second trajectory of the pair.
- the level of concentration of energy per component is equal to the minimum number of components concentrating an energy greater than or equal to a predefined ratio of the total energy.
- the energy level per component is defined by the index of the last component for which a derivative of the overall energy level of the components is greater than or equal to a predefined threshold.
- the invention also relates to a computer program product comprising program code instructions for the execution of the steps of a method according to one of the embodiments of the invention when said program is executed. on a computer.
- the invention also relates to a system comprising: at least one input port capable of receiving, for a current ATC situation defined by a current sector and a period of time, a set of parameters comprising, for the sector current, the trajectories of aircraft crossing the sector; at least one computing unit configured to perform a method according to one of the embodiments of the invention for computing a complexity index of the ATC situation.
- At least one calculation unit is configured to dynamically redefine the sectors of an airspace, from the complexity indices of the ATC situation calculated by said method.
- the at least one computing unit is configured to solve a constrained optimization problem, aimed at minimizing the total number of sectors in an airspace, while ensuring that the ATC complexity index calculated for each sector and period of time is less than a predefined complexity.

- FIG. 7a an example of calculating the complexity of a first ATC situation, in a set of embodiments of the invention.
- FIG. 1 represents an example of an air traffic control system, in which the invention can be implemented.
- the air traffic control system shown in FIG. 1 comprises a control tower 110, equipped with a radar 111 making it possible to locate the aircraft 120, 121 flying in a given sector.
- the control tower 110 can communicate with the aircraft, for example via a radio link, in order to give information and instructions to the aircraft, but also to receive information and requests from the aircraft.
- the control tower can receive data from external providers, such as a weather server 130.
- an air traffic controller can provide indications and instructions to the pilots of the aircraft from there. a set of data comprising the planned trajectories of aircraft in its sector, interactions with the pilots, and environmental data such as weather forecasts.
- FIG. 1 The system of Figure 1 is given by way of non-limiting example only, and the invention can be implemented in many systems for air traffic control, such as ATC or ATFM systems.
- FIG. 2 represents a set of sectors in which the invention can be implemented.
- Airspace is said to be controlled when aircraft maneuvers are subject to clearance, that is to say authorization by an air traffic controller.
- Figure 2 represents the airspace controlled in France.
- the French metropolitan territory is controlled by five control centers each controlling an FIR:
- the Reims center manages the FIR LFEE
- the Marseille center manages the FIR LFMM
- the Brest center manages the FIR LFRR.
- the FIRs cover airspace in France up to 19,500 feet; beyond that extends a UIR managed by the 5 control centers. These regions are in turn divided into control sectors, such as the so-called Regional Control Center (CCR) sectors, or ACC in English. Each of the sectors is permanently crossed by a certain number of aircraft. As explained above, the complexity of handling air traffic in a sector varies depending on the number of aircraft in this sector, but also other characteristics such as weather, or traffic density. So that the controllers can carry out their checks in good conditions, the number of controllers assigned to a sector can be modulated according to the complexity of its processing. The shape and size of the sectors can also be adapted.
- CCR Regional Control Center
- FIG. 3 represents a system for calculating the complexity of processing an ATC situation, in a set of embodiments of the invention.
- the system 300 may for example be an ATM, ATC or ATFM system, allowing air traffic controllers to control the air situation in a given sector.
- the system 300 is a calculation system. According to a set of embodiments of the invention, the system 300 may be a single computing device such as a computer, a server, or any other system capable of performing computer calculations. System 300 can also include a plurality of computing devices. For example, system 300 can be a server farm with multiple compute servers.
- the system 300 thus comprises at least one computing unit 310.
- the at least one computing unit 310 can be any type of computing unit capable of performing computer calculations.
- the computing unit may be a processor configured with machine instructions, a microprocessor, an integrated circuit, a microcontroller, a programmable logic circuit, or any other computing unit capable of being programmed to perform computing operations.
- the system 300 comprises at least one input port 320 capable of receiving a set of parameters relating to a current air situation in a sector.
- the input parameter set includes the trajectories 321 of aircraft passing through the sector. According to different embodiments, these trajectories can include instantaneous trajectories and / or predicted trajectories.
- meteorological information may for example consist of an indication that a given event (storm, thunderstorm, etc.) is taking place.
- a "storm" event can be defined when the parameters of the weather messages related to a storm exceed a predefined threshold.
- the input parameters can be received in different ways.
- aircraft trajectories can be received by radio communication with aircraft, through radar measurements, etc.
- Weather information can be received, for example, through measurements from a weather radar, by subscription to a weather service.
- At least one port 320 can be of different types: internet connection, radio link, etc.
- the invention is not restricted to one type of input port, and those skilled in the art will be able to tailor the reception of the input parameters to the available input channels.
- the different input parameters can be received on a single port, or several ports, of the same type or of different types.
- the trajectories of aircraft 321 can be received by radio link, and meteorological information by an Internet connection.
- trajectories of aircraft 321 can be expressed in different ways.
- trajectories can be expressed as 4D trajectories, with waypoints defined by latitude, longitude, and FL and time of way.
- the trajectories can also include, for each waypoint, an associated heading.
- a trajectory can also be associated with an aircraft type and / or a callsign (name of a given aircraft).
- These parameters correspond to real situations occurring in sectors at the periods of time considered. They thus define, for an ATC situation defined by a given torque (sector, period of time), the input parameters representative of the processing complexity of the sector.
- these parameters include the trajectories of aircraft which have crossed the sector.
- the at least one calculation unit 310 is also configured to calculate, from the input parameters, an ATC complexity index of the current situation.
- At least one calculation unit 310 is configured to execute the steps of a method according to the invention, such as for example the method 400 described with reference to FIG. 4.
- the system 300 can use it in various ways. For example, he can display it to at least one operator, for example an air traffic controller, by means of at least one screen 330. This allows the operator to verify that the number of air traffic controllers assigned to a situation / a given sector is adequate according to the complexity of these. It can also raise an alert, either if the ATC complexity of a situation is too great compared to the number of controllers assigned to its handling, or it is too low, in which case too many air traffic controllers are mobilized for this situation. .
- an air traffic controller for example an air traffic controller
- At least one computing unit 310 is configured to dynamically redefine the shape and size of the sectors, in order to form as few sectors as possible, while by ensuring that the ATC complexity of each sector is below a predefined threshold.
- This complexity threshold can for example be a threshold above which the sector becomes too complex to be processed by an air traffic controller.
- the ATC complexity of a situation represented by a sector can be calculated. This therefore makes it possible to solve a constrained optimization problem, recalculating at each iteration the complexity for each sector and period of time. This thus allows a dynamic allocation of the air sectors. For example, the sectorization of airspace can be redefined in one-hour periods.
- Complexity calculations can also be used to train a machine learning engine capable of automatically determining the complexity of an ATC situation.
- a machine learning engine capable of automatically determining the complexity of an ATC situation.
- the complexity calculation according to the invention can be used as the complexity to be predicted in this context.
- FIG. 4 represents a computer-implemented method for calculating the complexity of processing an ATC situation, in a set of embodiments of the invention.
- the method 400 can for example be implemented by the system 300, and all the embodiments discussed with reference to FIG. 3 are applicable to the method 400.
- the method 400 comprises a first step 410 of obtaining an ATC situation 340 defined by a sector and a period of time, and of a set of input parameters comprising, for the sector and the period of time , the trajectories of aircraft 321 crossing the sector.
- the trajectories of the aircraft are defined by a set of trajectory parameters comprising at least the positions of the aircraft. In a set of embodiments of the invention, they may also include other parameters such as horizontal and vertical velocities, temperature, etc.
- Input parameters can also include items other than aircraft paths, such as weather information.
- This step 410 may consist, according to various embodiments of the invention, in receiving, in real time, the description of a current ATC situation (sector, period of time, trajectory of aircraft crossing the sector) d 'an air traffic control system. It can also consist in obtaining the description of a past situation, for example by extracting this information from a database of past situations.
- the method 400 comprises a second step 420 of calculating, for each of the aircraft trajectories, the trajectory parameters at a set of identical time steps for all the trajectories.
- This step consists in determining, for a set of given time steps, the parameters of each aircraft at the time step. Indeed, the trajectories can be initially described by parameters at variable times for each aircraft. This step 420 therefore makes it possible to obtain the parameters of the aircraft, at the same time steps for all the aircraft. For example, this makes it possible to compare the positions of the aircraft at identical time steps, and therefore to better identify potential trajectory conflicts.
- the time steps can be obtained in different ways.
- the duration of the ATC situation can be sampled by regular time steps, either according to a target duration of the time steps (the duration of the time steps is then predefined, but not the number of time steps) , or by dividing the duration of the situation by a given number of time steps (the number of time steps is then predefined, but not the duration of the time steps).
- FIG. 5 represents an example of calculating the positions of aircraft trajectories according to a set of common time steps, in a set of embodiments of the invention.
- the graph 5000 represents three raw trajectories 5010, 5020 and 5030.
- the trajectories are represented in two dimensions, and the time associated with each of the positions defining the trajectory is represented on the time axis 5040.
- the positions defining the trajectory are represented by circles, and a thin line starting from the circle indicates the associated time on the time axis 5040.
- the invention is applicable to 3d trajectories associated with time information (or 4D trajectory, the positions of the aircraft being able to be defined by a latitude, a longitude, an altitude, and a temporal information).
- the trajectory 5010 is defined by the points 5011, 5012 and 5013, respectively associated with the times tson, tsoi2 and tsoi3.
- the graph 5000 shows that the times associated with the positions on the trajectories 5020 and 5030 are not the times. same.
- the position 5021 of the trajectory 5020 is associated with the time Î5021 which is different, although close, from the time tson . This difference between the times at which the positions of the aircraft are provided for the different trajectories makes it more difficult to characterize the position conflicts between aircraft.
- Step 420 therefore consists in modifying the representation of the trajectories, into a set of positions temporally aligned over the same time steps.
- the graph 5100 represents these trajectories 5110, 5120 and 5130 aligned in time, corresponding respectively to the trajectories 5010; 5020 and 5030.
- the time axis 5140 is identical to the time axis 5040.
- the trajectories 5110, 5120 and 5130 are each defined by the same number of positions aligned on the same time steps, in this case the steps time tsioi, tsio2, tsio3, tsio4, tsios and tsio6.
- the path 5110 is now defined by the positions 5111, 5112, 5113, 5114, 5115 and 5116 aligned on the time steps t 5i0i, t 5i o 2 , t 5i o 3 , t 5i o 4 ,
- the positions of the trajectories 5110, 5120 and 5130 can be obtained from those of the trajectories 5010, 5020 and 5030, in different ways. For example by interpolation of the trajectory with respect to the known positions on the trajectories 5010, 5020 and 5030. This interpolation can be carried out in different ways, for example via linear interpolation, or B-splines.
- positions 5111 and 5121 directly provide information on the relative proximity of aircraft on trajectories 5110 and 5120, because they are aligned on the same time step ts-io-i, which was not the case for positions 5011 and 5021.
- other parameters of the trajectories are known, in addition to the positions on the raw trajectories 5010, 5020, and 5030, and determined (for example interpolated) at the times t 5i0i , t 5i o 2 , t 5i03 , t 5i o 4 , tsios and Î5106 for trajectories 5110, 5120 and 51030.
- this may be the case for the horizontal and vertical speeds of aircraft, their heading, or even the temperature. exterior.
- These parameters can, for example, help to obtain a better estimate of the trajectories at different times, and therefore to obtain a better estimate of the conflicts.
- Other parameters can be calculated directly on the positions of the temporally aligned trajectories 5110, 5120 and 5130. This is for example the number of conflicts, the distance or even the minimum separation between two aircraft.
- the method 400 comprises a third step 430 of forming a matrix comprising, for each possible pair of trajectories, the parameters of the trajectories of the torque at said time steps.
- This step consists in inserting into a matrix, for each of the pairs, the parameters at the same time steps.
- each trajectory forms N-1 pairs, with the N-1 other trajectories respectively, and the total number of pairs is equal to N * (N-1) / 2.
- the parameters of the two trajectories of the couple are noted, for each of the time steps.
- each parameter of a trajectory will be noted N-1 times (for each of the N-1 pairs that the trajectory forms) in the matrix.
- FIG. 6 represents an example of a matrix of parameters by pair of trajectories, according to a set of embodiments of the invention.
- the matrix 600 represents the parameters of the trajectories at time steps, organized by pairs of trajectories.
- N trajectories are present on the sector, denoted A1, A2, ... AN.
- the trajectory parameters only include position parameters: longitude, latitude, altitude (in the form of an FL - Flight Level), for each time step.
- the number of time steps is equal to p. Only the positions being taken into account, these different time steps / positions are noted Pos1, Pos2 ... Posp.
- Each line corresponds to a pair of trajectories.
- the lines 610, 611, 612 correspond respectively to the pairs of trajectories (A1, A2), (A1, A3), and (AN-1, AN).
- the columns are grouped by successive time steps / positions. For each of the successive time steps / position, the columns represent successively the latitude of the point at the time step for the first then the second trajectory of the couple, the longitude of the point at the time step for the first then the second trajectory of the couple then the flight level of the point at the time step for the first then the second trajectory of the couple.
- the columns represent successively the latitude of the point at the time step for the first then the second trajectory of the couple, the longitude of the point at the time step for the first then the second trajectory of the couple then the flight level of the point at the time step for the first then the second trajectory of the couple.
- - cell 630 located on first column 620 and first line 610, represents the value of the latitude of the first trajectory A1 of the first pair (A1, A2) at the first time step p1;
- - Cell 631 located on second column 621 and first line 610, represents the value of the latitude of the second trajectory A2 of the first pair (A1, A2) at the first time step p1;
- the cell located in the first column 620 and the second row 611, represents the value of the latitude of the first trajectory A1 of the second couple (A1, A3) at the first time step p1. Its value is therefore equal to that of cell 630;
- - cell 633 located in the last column corresponding to the second time / position step, and the last row 612, represents the flight level value of the second trajectory AN of the second pair (AN-1, AN) at the second step time p2.
- Figure 6 is provided by way of example only of a matrix of parameters according to the invention. However, other representations are possible.
- the order of the parameters or pairs of trajectories can be modified (for example, we could have the columns representing the longitude before those representing the latitude, and the pairs of trajectories can be interchanged). More generally, other parameters than the trajectory (horizontal speed, vertical speed, heading %) can be used, and the matrix can be defined so that:
- each row of the matrix represents a pair of trajectories
- the columns of the matrix represent respectively, by successive time steps, the values of each of the parameters of the trajectories, for the first and then for the second trajectory of the pair.
- a matrix such as matrix 600 comprises in a single matrix all the information relating to an airline sector.
- the parameters of the aircraft for each pair of trajectories and each time step are concatenated into a single vector, of dimension 6 (when 3 parameters latitude, longitude altitude are taken into account. count, or more generally twice the number of parameters).
- the matrix is a tensor, of dimensions N (N-1) / 2, p, and 6 (when 3 parameters latitude, longitude altitude are taken into account, or more generally 2 times the number of parameters) .
- the representation of the matrix can be adapted.
- the rows and columns could be reversed - we would then have one column per couple of trajectory, and one line per parameter of a trajectory of a couple at a time step.
- the method 400 comprises a fourth step 440 of applying to the matrix a transformation having the property of concentrating energy by component.
- This transformation can for example be an analysis by principal component (PCA in French, or PCA in English), or an analysis by independent component (ACI in French or ICA in English).
- PCA principal component
- ACI analysis by independent component
- IVA Independent Vector Analysis in English, or Independent Vector Analysis (AVI) in French).
- An IVA is described in particular by D. Lahat, T. Adali and C. Jutten, “Multimodal data fusion: An overview of methods, challenges, and prospects," Proc. IEEE, vol. 103, no. 9, pp. 1449-1477, Sep. 2015, and is particularly indicated when the matrix is in the form of a tensor.
- the method 400 then comprises a fifth step 450 for calculating the energy by component.
- This step consists in calculating for each of the components of the transformed matrix, an energy value.
- the energy of a component can for example be calculated as the sum of the squares of the elements of the component.
- the method 460 then comprises a sixth step of calculating a complexity index of the ATC situation, as a function of a level of concentration of energy by component.
- This step consists in determining to what point the energy is concentrated on the first components, and to deduce therefrom the complexity of the situation.
- the energy is very concentrated on a few components, this means that all the information contained in the interactions between the pairs of trajectories can be summarized on a small number of dimensions, which indicates a low complexity of the situation. For example, if many trajectories are parallel, the information can be summarized in few dimensions, and the complexity of handling the ATC situation is low.
- the energy is not very concentrated, and distributed over many components, this means that the interactions between the trajectories require many dimensions to be correctly represented, which suggests many trajectory conflicts, and a high complexity of the trajectories. the ATC situation.
- the components can be sorted in order of increasing energy.
- the level of energy concentration is defined by a number K of principal components, which concentrate a ratio of the total energy of the components greater than or equal to a threshold predefined P_K.
- the level of energy concentration can be defined by the number of components concentrating 99% of the total energy of the components.
- the index can be obtained in various ways. For example, it may simply be the number of components required to exceed the predefined energy threshold P_K.
- FIGS. 7a and 7b represent two examples of calculating the complexity, respectively of a first and of a second ATC situation, in a set of embodiments of the invention.
- the energy level per component is defined by the index of the last component for which a derivative of the overall energy level of the components is greater than or equal to one. predefined threshold.
- a derivative of the overall energy level of the components is greater than or equal to one. predefined threshold.
- the complexity of handling the ATC situation is thus defined by the following formula:
- - k is the index of the last component bringing a lot of energy, i.e. the component with k the largest such as the derivative of the total energy of the components, represented by E ck - E c fc _i ) is greater than or equal to a predefined threshold;
- - k max is the index of the component for which the sum of the energies is greater than or equal to a predefined threshold of the total energy.
- This calculation therefore makes it possible to determine the complexity of the ATC situation, as a function of the number of components providing a significant contribution to the total energy. It therefore allows a very reliable estimate of the complexity of handling the situation.
- the derivative can be a central derivative, and not a derivative on the right, the formula then becomes:
- FIG. 7a represents a first application of this calculation, to a first ATC situation.
- Label 710a provides a synthetic representation of this situation, in which the trajectories of the aircraft are represented in 2D in the space of the air sector. This first situation is relatively uncomplicated, because many trajectories are substantially parallel.
- Graph 720a represents the cumulative percentage of total energy by principal component index. The horizontal axis represents the index of the current component, and the vertical axis represents the cumulative energy of the components, from the first component to the current component, as a percentage of the total. For example, point 721a means that the 1 st component alone concentrates 30% of the total energy, point 722a that the first two components together concentrate a little less than 50% of the total energy, etc.
- the inflection point at which the derivative of the total energy is below the threshold corresponds to the point 723a, and thus the 3rd component. This means that the components from the 4 th contribute little to the total energy.
- the index k max from which almost all of the energy is concentrated corresponds to the 11th component 724a.
- FIG. 7b represents a second application of this calculation, to a second ATC situation.
- the sticker 710b represents the 2D trajectories of the aircraft in this situation, on the same principle as the sticker 710a.
- This second situation although comprising a number of trajectories identical to that of the first situation, is more complex, because the trajectories intersect much more frequently.
- Label 720b represents the change in total energy, by principal component, on the same model as label 710b.
- the inflection point at which the derivative of the total energy is less than the predefined threshold is obtained at point 721 b corresponding to the 8 th component, and the index k max from which the almost all of the energy is concentrated corresponds to the 13th component 722b.
- 8 components therefore contribute a great deal to the total energy, and the calculated complexity index is equal to 0.81686, and is therefore greater than that of the first situation.
- the method 400 includes many advantages.
- each of the steps of method 400 can be carried out by relatively simple calculations, and in a deterministic manner. Method 400 can therefore be executed in a limited time, on limited computational capacities.
- the overall algorithmic complexity of method 400 is low compared to known methods for determining the complexity of handling an ATC situation.
- the method 400 thus makes it possible to redefine ATC sectors in real time in order to adapt the workload of the air traffic controllers.
- Method 400 is therefore likely to be certified.
