Monitoring infrastructure facilities by means of geo-clustering

A non-transitory computer readable medium having computer-executable instructions stored thereon for performing a method for monitoring infrastructure facilities of a route network for vehicles, the vehicles generating messages about their respective operating state, the messages being transmitted with an associated time and location specification that represent an occurrence of a signaled operating state, to a land-based evaluation device, the messages are received by the land-based evaluation device, stored in a database and evaluated, wherein the method performed by the computer executable-instructions, which are stored on the non-transitory computer readable medium, comprises the following method steps of:

• reading out the messages of a predefined time period relating to at least one predefined operating state from the database;
• determining limited areas with a frequent occurrence of the predefined operating state by means of a-predefined automatic segmentation algorithm by grouping location specifications, wherein a maximum distance between locations of the occurrence of the predefined operating state is defined in dependence on the predefined operating state;
• identifying the infrastructure facilities in the limited areas having the frequent occurrence of the predefined operating state as a possible cause of the predefined operating state of the vehicles;
• outputting, on a screen, information about the infrastructure facilities which are identified as the possible cause of the predefined operating state of the vehicles;
• reading out at least one additional message which relates to the at least one predefined operating state from the database, the additional message is associated with a time that represents an occurrence of the signaled operating state, which follows a specified time period;
• using the predefined algorithm to determine whether the at least one additional message should be assigned to a limited area having frequent occurrence of the predefined operating state, and if the at least one additional message should be assigned to the limited area with the frequent occurrence of the predefined operating state;
• identifying the infrastructure facilities of the limited area having the frequent occurrence of the predefined operating state as the possible cause of the predefined operating state of the vehicles;
• and
• outputting, on the screen, at least one information item about the infrastructure facilities that are identified as the possible cause of the predefined operating state of the vehicles.
