One of the biggest improvements they made - was the ability to stop on a floor - then change direction. The first elevators had to travel the whole length of the building - either up or down - before they could reverse direction. This wasted time for people wanting to use them - as they had to wait for the elevator to return to their floor in the direction they wanted to co. Computerised controls now allow an elevator to (for example) travel up from the ground floor to - say - the 3rd floor - then go back down to the 2nd, and up again to the 5th.
