USE OF SAMPLING IN BUS-LINE DATA COLLECTION

Bus lines require periodic data collection for performance evaluation and efficient operation. The potential of using statistical methods in the collection of individual bus-line data is investigated. A particular bus line was chosen as an example. By using prior, conventionally collected data of that line, a suitable sampling method and estimation technique were developed. The sampling plan was applied to data collection in June 1980. The results demonstrate that sampling (a) gives the necessary precision while permitting more efficient use of manpower and (b) allows the flexibility needed to focus on data of interest. It is concluded that, with the establishment of appropriate guidelines for its use, sampling will provide a valuable tool to bus transit.
