説明
In recent years a large number of models have been developed to make up the actual OD matrix more precise from traffic counts. An important aspect of the model is the precision of the estimated OD matrix. Because traffic counts are generally not enough to identify the actual OD matrix, it is necessary to evaluate the accuracy of the estimated one. This paper presents some theoretical investigations into the reliability of the estimated OD matrix employing the concept of Maximum Possible Relative Error (MPRE). It is shown that the MPRE can be formulated as a simple quadratic programming problem. The proposed MPRE shows the upper bound for the real relative error and plays an important role in the reliability evaluation of the estimated OD matrix.
