Methods for identifying vehicle idling

A method comprising:

• identifying, by at least one processor, a plurality of idling events for a plurality of vehicles, comprising:
• identifying each idling event of the plurality of idling events as a period of time where an engine of a respective vehicle of the plurality of vehicles is active and the respective vehicle is not in motion;
• identifying, by the at least one processor, a subset of select idling events of the plurality of idling events comprising, for each idling event of the plurality of idling events:
• determining a duration of the idling event;
• comparing data representing the idling event to acceptability criteria, the acceptability criteria including at least a first temporal threshold and a second temporal threshold higher than the first temporal threshold, where the acceptability criteria define acceptability for the idling event as at least a duration of the idling event being less than the first temporal threshold or greater than the second temporal threshold;
• and
• identifying the idling event as a select idling event if the data representing the idling event does not satisfy the acceptability criteria, when a duration of the idling event is between the first temporal threshold and the second temporal threshold;
• determining, by the at least one processor, a fuel consumption for the subset of select idling events;
• and
• output, by at least one output device, an indication based on the fuel consumption and the subset of select idling events.
