A method that develops a passenger origin-destination (O-D) table for a transit line is presented. The input to the model is the boarding and a lighting counts at stations, and the output is the estimated passenger volume for each station pair. The method can make use of the analyst's knowledge of passenger volumes for selected station pairs if it is available in an approximate range. The O-D volumes are estimated to minimise the expected error by locating each estimate as close to the centre of the feasible solution space as possible;this is accomplished by a linear programming method. The estimates can be revised iteratively by incorporating the analyst's knowledge of the passenger travel pattern. Examples include the case for which only the nondirectional boarding and a lighting counts are available. (Author/publisher)
