Abstract: The use of mainframe, mini and microcomputers has become widespread among transportation engineers and planners as a means of improving the comprehensiveness and accuracy of data analysis while reducing the costs and the time delays involved with the processing of data. In recent years, there has been increasing attention given to the need for improved data-collection techniques to complement automated, data processing capabilities. As a result, equipment has been designed and manufactured which automatically collects or records source data. One of the earliest automated data collection (ADC) devices includes the pneumatic tube traffic counter. More recent examples of electronic collectors include automated fare boxes, pass readers, fuel-metering devices, vehicle-monitoring devices, passenger counters, light pens, touch screens, bar-code readers and lap-size, battery operated portable computers.
