Video analytics based advanced elevator dispatching

A building elevator system having a plurality of elevator systems organized into an elevator group, the building elevator system comprising:

• a processor;
• a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
• detecting crowd data within an elevator lobby proximate the elevator group on a landing;
• determining a level of crowdedness in response to the crowd data;
• determining at least two elevator cars of the plurality of elevator systems are required in response to the level of crowdedness;
• dispatching an elevator car of a first elevator system of the plurality of elevator systems to the landing;
• dispatching an elevator car of a second elevator system of the plurality of elevator systems to the landing;
• and
• coordinating an arrival time of the elevator car of the first elevator system at the landing and an arrival time of the elevator car of the second elevator system at the landing.
