intensity is detected, the traffic intensity being a number of passengers arriving at the at least one elevator during a traffic intensity determination period, a traffic amount value is determined by comparing the traffic intensity to a maximum building population, wherein the maximum building population is a maximum number of people in a building, and the at least one elevator is controlled based on the determined traffic amount value. ## Claims ### Claim 1 A method for controlling an at least one elevator comprising detecting an arriving traffic intensity, the traffic intensity being a number of passengers arriving at the at least one elevator during a traffic intensity determination period, determining a traffic amount value by comparing the traffic intensity to a maximum building population, wherein the maximum building population is a maximum number of people in a building, and controlling the at least one elevator based on the determined traffic amount value, wherein the method further comprises. detecting persons arriving into the building from entrance floors and persons leaving the building from the entrance floors, adding the number of detected persons arriving into the building from the entrance floors to a basic building population number, subtracting the number of detected persons leaving the building from the entrance floors from the basic building population number, determining a maximum number of the basic building population number during a building population determination period as the maximum building population, and updating the maximum building population for each building population determination period. ### Claim 2 (depends on 1) The method according to claim 1, wherein the traffic amount value is a value which indicates a percentage of the detected traffic intensity to the maximum building population. ### Claim 3 (depends on 1) The method according to claim 1, wherein the traffic amount value is a traffic level which indicates a range of percentages of the detected traffic intensity to the maximum building population. ### Claim 4 (depends on 1) The method according to claim 1, wherein the maximum building population is updated by using a smoothing method. ### Claim 5 (depends on 1) The method according to claim 1, further comprising detecting the number of persons arriving into or leaving the building by using a weighting device and/or a light sensor and/or a camera based system. ### Claim 6 (depends on 1) The method according to claim 1, wherein the building population determination period is longer than the traffic intensity determination period. ### Claim 7 (depends on 1) The method according to claim 1, wherein a group of elevators is controlled, and the group of elevators is controlled based on the determined traffic amount value. ### Claim 8 A control device for controlling at least one elevator, wherein the control device comprises a controller configured to detect an arriving traffic intensity, the traffic intensity being a number of passengers arriving at the at least one elevator during a traffic intensity determination period, determine a traffic amount value by comparing the traffic intensity to a maximum building population, wherein the maximum building population is a maximum number of people in a building, and control the at least one elevator based on the determined traffic amount value, wherein the controller is further configured to detect persons arriving into the building from entrance floors and persons leaving the building from the entrance floors, add the number of detected persons arriving into the building from the entrance floors to a basic building population number, subtract the number of detected persons leaving the building from the entrance floors from the basic building population number, determine a maximum number of the basic building population number during a building population determination period as the maximum building population, and update the maximum building population for each building population determination period. ### Claim 9 (depends on 8) The control device according to claim 8, wherein the traffic amount value is a value which indicates a percentage of the detected traffic intensity to the maximum building population. ### Claim 10 (depends on 8) The control device according to claim 8, wherein the traffic amount value is a traffic level which indicates a range of percentages of the detected traffic intensity to the maximum building population. ### Claim 11 (depends on 8) The control device according to claim 8, wherein the controller is further configured to update the maximum building population by using a smoothing method. ### Claim 12 (depends on 8) The control device according to claim 8, wherein the controller is further configured to detect the number of persons arriving into or leaving the building by using a weighting device and/or a light sensor and/or a camera based system. ### Claim 13 (depends on 8) The control device according to claim 8, wherein the building population determination period is longer than the traffic intensity determination period. ### Claim 14 (depends on 8) The control device according to claim 8, wherein a group of elevators is controlled, and the group of elevators is controlled based on the determined traffic amount value. ### Claim 15 (depends on 1) A computer program product comprising code means for performing a method according to claim 1 when run on a processing means or module. ### Claim 16 (depends on 15) The computer program product according to claim 15, wherein the computer program product is embodied on a computer-readable medium, and/or the computer program product is directly loadable into the internal memory of the computer and/or transmittable via a network by means of at least one of upload, download and push procedures. ### Claim 17 (depends on 2) The method according to claim 2, wherein the traffic amount value is a traffic level which indicates a range of percentages of the detected traffic intensity to the maximum building population. ### Claim 18 (depends on 2) The method according to claim 2, further comprising detecting the number of persons arriving into or leaving the building by using a weighting device and/or a light sensor and/or a camera based system. ### Claim 19 (depends on 3) The method according to claim 3, further comprising detecting the number of persons arriving into or leaving the building by using a weighting device and/or a light sensor and/or a camera based system. ### Claim 20 (depends on 4) The method according to claim 4, further comprising detecting the number of persons arriving into or leaving the building by using a weighting device and/or a light sensor and/or a camera based system.
