| Outline of Final Research Achievements |
We firstly summarise the satisfaction factors by factor analysis and analyse the correlation between the satisfaction of the bus service, the recognition of the bus service and whether the bus is included in the choice set. Then, we apply a structural equation analysis to evaluate the interdependency of these factors. As a result, we reveal that the recognition of bus network affects the satisfaction of the bus service, and the satisfaction of the bus service affects whether the bus is included in the choice set.
Then, in order to evaluate the effect of heterogeneity of choice set onto transportation network, we further proposes a combined mode and route choice equilibrium model considering heterogeneity in mode choices in order to measure the influence of inherent mode preferences and cost sensitivities on network flows. As the result of case study, we find that a change in class composition affects the overall mode choice ratio without changing the network level of service.
