Modelling Mode Choice in Passenger Transport with Integrated Hierarchical Information Integration

In this paper, the HII-I approach is applied to model the mode choice between a regional train, a (hypothetical) regional bus and a car (only available for car users). Test results show that process equality is given when analysing only the data of the bi-modal sub-experiments whereas the assumption of process equality is rejected for data of the tri-modal sub-experiments, where differences in error variances between the sub-experiments are found. This empirical finding suggests that it is possible to construct separate sub-experiments while arriving at a single concatenated model.
