Abstract
A MODIFICATION TO THE TRANSPORTATION PROBLEM THAT TAKES ACCOUNT OF SUB-OPTIMALITY HAS PREVIOUSLY BEEN RARELY AND INCAUTIOUSLY APPLIED. A METHOD OF IMPLEMENTING THE MODIFICATION BY ITERATION IS OUTLINED THAT MINIMIZES AN APPROPRIATE GOODNESS-OF-FIT STATISTIC. THE MODEL IS THEN APPLIED, USING THIS METHOD, TO FREIGHT FLOW DATA IN BRITAIN. A FREIGHT FLOW MATRIX IS PREDICTED THAT IS SUPERIOR TO A TRANSPORTATION PROBLEM PREDICTION AND BEHAVIOURAL AND ECONOMIC IMPLICATIONS ARE DERIVED TO DEMONSTRATE THE INSIGHTS THAT THE TECHNIQUE CAN YIELD.(Author/publisher).
