A method of electronically generating person related price values and/or bonus values for persons waiting in a queue in front of a target point in dependency of the length of the queue of the waiting persons, characterized by the following steps: a) A detection device which comprises a device for generating images, which comprises a camera, as well as a device for analysing images, continuously detects via said camera the number of persons in the queue in front of the target point, analyses by means of said device for analysing images those images being continuously acquired by said camera with regard to the position pf each single person in said queue in relation to said target point, while it is checked through said device for analysing images by means of suitable evaluation algorithms, in which way the distance of a person waiting in the queue in front of the target point changes between successive images, in order to successively generating statements, where and in which distance the person is located to said target point, and thereof it generates person-position-data being related to said target point; b) In a computer device, person related waiting times until the reach of said target point are electronically calculated for each person from said generated person-position-data; c) In a computing device for at least a subset of the persons in said queue a person related price value in the form of a determined price and/or a person related bonus value in the form of a discount value is being calculated from the calculated waiting times, as soon as the calculated person related waiting time for a person exceeds a predefined threshold in the form of an acceptable waiting time, or on the basis of defined time intervals in relation to the calculated waiting time; d) The calculated person related price value and/or bonus value is electronically displayed and/or is electronically made available to the respective person, while a communication device is being provided at said target point, while a communication link is being established between said communication device and an electronic end terminal being associated to said person, and while by means of said communication link the calculated person related price value and/or the calculated person related bonus value is transmitted to said electronic end terminal. a) A detection device which comprises a device for generating images, which comprises a camera, as well as a device for analysing images, continuously detects via said camera the number of persons in the queue in front of the target point, analyses by means of said device for analysing images those images being continuously acquired by said camera with regard to the position pf each single person in said queue in relation to said target point, while it is checked through said device for analysing images by means of suitable evaluation algorithms, in which way the distance of a person waiting in the queue in front of the target point changes between successive images, in order to successively generating statements, where and in which distance the person is located to said target point, and thereof it generates person-position-data being related to said target point; b) In a computer device, person related waiting times until the reach of said target point are electronically calculated for each person from said generated person-position-data; c) In a computing device for at least a subset of the persons in said queue a person related price value in the form of a determined price and/or a person related bonus value in the form of a discount value is being calculated from the calculated waiting times, as soon as the calculated person related waiting time for a person exceeds a predefined threshold in the form of an acceptable waiting time, or on the basis of defined time intervals in relation to the calculated waiting time; d) The calculated person related price value and/or bonus value is electronically displayed and/or is electronically made available to the respective person, while a communication device is being provided at said target point, while a communication link is being established between said communication device and an electronic end terminal being associated to said person, and while by means of said communication link the calculated person related price value and/or the calculated person related bonus value is transmitted to said electronic end terminal.
