NESTED LOGIT TRAVEL DEMAND MODELS FOR MORE THAN TWO ALTERNATIVES IN URBAN CORRIDORS

The nested logit model (nl) is a generalisation of the simple or multinomial logit (mnl) model that copes with the "independence from irrelevants alternatives" problem of the latter. Being a generalisation, however, means that it is more difficult and expensive to calibrate and use. This paper uses data for the Garforth-Leeds corridor in west Yorkshire (1975 based) and for the Las Condes-CBD corridor in Santiago, Chile (1981 based) to calibrate mnl and nested logit models for these two different environments, in order to analyse and evaluate the justification of the use of more general specifications as the nl. The problem of structural specification of nl models in practice is also addressed. For the British case a comparison is also made of aggregate and disaggregate n. specifications. (Author/TRRL)
