Lift Passenger Traffic Patterns: Applications, Current Knowledge, and Measurement

In order to calculate the performance of a new or refurbished lift installation we need to estimate likely passenger traffic patterns. These traffic patterns are also recognised by the lifts’ traffic control system which adjusts the dispatcher algorithm accordingly. In this paper the authors summarise current, published knowledge of lift passenger traffic patterns and review these against actual survey results. Having identified a need to improve our knowledge of passenger traffic patterns, various means of collecting data are discussed including: manual surveys, computer vision techniques, infra-red counters, and analysis based on data logged by lift traffic control systems or traffic analysers.
