ABSTRACT
This chapter presents a case study of a nine storey building where there are three basement parking areas. The population on floors will all reach their work destinations using the lifts, whether they arrive via the basements, or via floor G. The effect of some persons arriving directly at the G floor and not using the lifts can be considered to balance other persons travelling to the G floor from the basements, and therefore alighting at the G floor. The arrival of cars into a car park is generally limited by the number of entry ramps. The peak arrivals at the ground floor can occur in a worst case scenario at the same time as the peak arrivals from the basements. The arrivals at the three basement floors are larger than the numbers arriving at the ground floor.
