THE CALIBRATION OF THE NORMAL MARGINAL DISUTILITY MODAL SPLIT MODEL

With the present interest being shown by government in public transport, demands are being made on the transport planners for improved choice of travel mode modelling techniques. Many models in the past have merely "explained" a high proportion of the variance in the data and consequently their explanatory power is only a causal illusion. To use such models predictively, one must be confident that the invisible relationships underlying the data will continue unchanged through time; this is at best A dubious assumption. The model tested is based on utilitarian theory and can therefore be examined from both theoretical and empirical viewpoints. Until now only hand methods of calibration have been used. A statistical method of calibration using data from Australian cities as input has been developed. (A) /TRRL/
