This paper reports on a project that simulates the behaviour of a passenger lift in the Manchester Metropolitan University (MMU) Law School building and aims to develop effective strategies so that the average waiting time of passengers could be reduced as well as reducing the distance travelled by the lift car. Site investigation is firstly carried out to observe the behaviour of lift, and to obtain lift usage data. This project seeks to provide a more efficient and effective lift call strategy based on using WITNESS 13 simulation software. A base model representing the current installation was developed leading to a number of experiments designed to test different lift call strategies. In comparison to the base model the improvedstrategic model is able to reduce the average passenger queue waiting time by nearly 15%. Unfortantly the reduction in the queue waiting time came at the expense of marginally increasing the distance travelled by the lift cars during the peak period. Overall the the project was deemed successful opening lots of scope for further scenario testing.
