A study to determine whether statistics on bus passenger boarding and alighting movements could be recorded by electro-mechanical means revealed that several systems were in various stages of development: ProData counter utilizing an infrared beam-cutting principle; Automatic Switch Company (ASCO) counter utilizing an ultrasonic sound beam-cutting principle; the Honeywell counter which is a pressure mat consisting of 2 basic subsystems (transducer mat and the electronic package); Scope counter which consists of a series of foot actuated sensors and a microprocessor which interprets the sensor outputs; Vitro counter which detects and measures the transit time of 40 KHZ acoustic pulses reflected by objects that are ascending or descending the bus steps. Details of the test program and the analysis of the data are presented. ASCO was found to overcount, and Honeywell and ProData to undercount passenger movement. The Scope counter overcounted boarding and undercounted alighting movements, Vitro undercounted both types of movement. The need is indicated for further work on reliable, low-cost passenger counters.
