Spatio-temporal key performance indicators

A method implemented by an information handling system that includes a memory and a processor, the method comprising:

• defining a plurality of geographic areas respectively corresponding to geographic portions of a city environment;
• for each geographic area of the plurality of geographic areas, receiving a user selection of one or more sensors, selected from a plurality of sensors, wherein the plurality of sensors comprises one or more permanent sensors and one or more temporary sensors, and wherein the plurality of sensors further comprises one or more cameras and one or more noise detection sensors;
• for each geographic area of the plurality of geographic areas, tracking a plurality of metrics, wherein the tracking is performed at a plurality of times, and wherein the metrics are obtained from the one or more selected sensors that perform the tracking in near-real-time;
• for each geographic area of the plurality of geographic areas, determining, by the processor, a spatio-temporal key performance indicator crowd density value (S-T KPI CDV) corresponding to the geographic area at each of the plurality of times;
• for each geographic area of the plurality of geographic areas, calculating, by the processor, a crowd density projection value for the geographic area based, at least in part, upon the S-T KPI CDVs for the geographic area, with the crowd density projection value reflecting a predicted crowd density for a future time occurring subsequent to the plurality of times;
• and
• in response to determining that a first crowd density projection value for a first geographic area exceeds a first predetermined threshold value, alerting a device of a law enforcement official.
