Display control device, display control method, and displaycontrol program

A display control method in which a computer executes processing including:

• estimating, on the basis of a predictive distribution of an occurrence point representing a point where a call for an emergency vehicle occurs, an occurrence time at which a call occurs at the occurrence point for each of a plurality of the occurrence points;
• executing a simulation of an emergency activity in which any one of a plurality of the emergency vehicles available for dispatch is dispatched to the occurrence point at the occurrence time for each of the plurality of occurrence points on the basis of the occurrence time of each of the plurality of occurrence points as an estimation result and an operational status of each of the plurality of emergency vehicles;
• on the basis of a simulation result, extracting, from the plurality of occurrence points, an occurrence point at which a distance between the emergency vehicle available for dispatch and the occurrence point is equal to or greater than a threshold value, and calculating a risk level such that the risk level of an area to which the extracted occurrence point belongs becomes high;
• and
• controlling a display unit to display the calculated risk level.

A computer-readable non-transitory recording medium storing computer-executable program instructions that when executed by a processor cause a computer to execute a display control method comprising:

• estimating, on the basis of a predictive distribution of an occurrence point representing a point where a call for an emergency vehicle occurs, an occurrence time at which a call occurs at the occurrence point for each of a plurality of the occurrence points;
• executing a simulation of an emergency activity in which any one of a plurality of the emergency vehicles available for dispatch is dispatched to the occurrence point at the occurrence time for each of the plurality of occurrence points on the basis of the occurrence time of each of the plurality of occurrence points as an estimation result and an operational status of each of the plurality of emergency vehicles;
• on the basis of a simulation result, extracting, from the plurality of occurrence points, an occurrence point at which a distance between the emergency vehicle available for dispatch and the occurrence point is equal to or greater than a threshold value, and calculating a risk level such that the risk level of an area to which the extracted occurrence point belongs becomes high;
• and
• controlling a display unit to display the calculated risk level.
