THEORETICAL ASPECTS OF THE GRAVITY MODEL OF TRANSPORT PLANNING

The gravity model (for trip distribution) of the type studied by transportation planning theorists is investigated as a theoretical construct. Deficiencies in the widely accepted maximum likelihood and maximum entropy derivations of the model are pointed out. An attempt is made to establish a sound calibration procedure for the model, whilst recognising that the gravity model need not necessarily be a good descriptor of trip distribution. /Author/TRRL/
