Uppeak Revisited

It was once thought that the only way to efficiently service uppeak traffic was to force cars to return to the main terminal after every trip. However, there are a number of techniques (made possible by modern computer technology), which now make this oversimplification invalid. These include uppeak Subzoning (divide the building into two); uppeak Sectoring (give each lift a set of floors to serve) and Hall Call Allocation (find out where passengers want to go, before letting them into the car). A comparison is made of these three techniques and Hall Call Allocation with uppeak subzoning; using the conventional uppeak service regime as a reference.
