Problem: People in hotels, apartment complexes and office buildings always seem to wait on elevators, regardless of the floor they are on. This is especially true in less trafficked buildings.
Concept: Smarter elevators that reduce wait time.
Details: When user opens certain doors on a given floor, the elevator is called for that floor. For the ground floor, there would be a double-sensor to differentiate between users going into the building and users exiting a building. To further prevent confusion for when two or more users pass through this double-sensor system, a timeout delay would be in place based on the average human walking speed. If the sensors go off within 1/10 second of each other, either the person is running (unlikely) or two people are approaching the sensors from opposing sides.
