Traffic assignment studies, which are instrumental in transportation plan evaluation, require an origin destination trip table as input. A method of estimating the trip table from observed link volumes within the framework of small-area assignment is described. The technique is based on solution of an optimization problem and is compatible with equilibrium traffic assignment assumptions. It thus differs significantly from previous methods based on statistical estimation. Because it avoids expensive home-interview surveys and time-consuming work with trip generation and distribution models, the method provides an attractive and cost-effective alternative analysis procedure for small and medium-sized communities. It is likely to be particularly effective in the evaluation of short-term, low-capital improvements in the transportation network. (Author)
