In this paper some experimental sequential models for the simulation of trip-chains are presented; the models have been calibrated on the basis of a survey made in a medium-sized town. This work is part of a research, effected by the Department of Regional Planning of the University of Calabria, to forecast travel demand and to analyze travel behavior of the transport system users (Festa et al., 2000). The travel choices of individuals have been reproduced simulating the decisional process in sequential steps, by models based on the random utility theory. The tour generation models, proposed by Festa et al. (2001), have been once again calibrated introducing a new set of variables in the systematic utility function of the alternatives of choice. Some models for the travel type choice simulation are also presented; the models have a Binomial Logit functional structure, with trip-tour and trip-chain as choice alternatives.
Nell’articolo sono riportati modelli sperimentali per la simulazione delle catene di spostamenti che riproducono la fase di generazione dei viaggi e la fase della scelta del tipo di viaggio. I modelli, di natura comportamentale, tengono conto di come le scelte di viaggio degli utenti sono influenzate dalle scelte dei componenti del nucleo familiare. Nella nota è riportata una interpretazione quantitativa dei risultati ottenuti dalle calibrazioni, che è stata effettuata tramite l’analisi degli Odds Ratio, ed una analisi di sensitività dei modelli proposti.

Abstract
In this paper some experimental sequential models for the simulation of trip-chains are presented; the models have been calibrated on the basis of a survey made in a medium-sized town. This work is part of a research, effected by the Department of Regional Planning of the University of Calabria, to forecast travel demand and to analyze travel behavior of the transport system users (Festa et al., 2000). The travel choices of individuals have been reproduced simulating the decisional process in sequential steps, by models based on the random utility theory. The tour generation models, proposed by Festa et al. (2001), have been once again calibrated introducing a new set of variables in the systematic utility function of the alternatives of choice. Some models for the travel type choice simulation are also presented; the models have a Binomial Logit functional structure, with trip-tour and trip-chain as choice alternatives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
