Presentation

Beyond Traditional Variables: A Statistical Framework for Modeling Complex Travel Behaviors and Preferences in New Zealand

Recent studies have shown that behavioural variables, such as attitudes, serve as significant predictors of travel mode choices. However, few transport models have effectively incorporated these variables, often relying on fuzzy estimations that limit predictive accuracy. This study employs exploratory factor analysis to identify key latent constructs influencing travel behaviour and uses structural equation modelling to examine the causal relationships of various latent variables and journey experience by different travel modes.

We analyse data from New Zealand residents across varying transport modes, demographic segments, and regional differences. Key factors affecting travel experience, including safety, value for money, and ease of use, are identified. Results indicate significant regional variances. This research highlights the importance of habit formation in transport decisions and recommends infrastructure enhancements alongside interventions that foster positive travel experiences to promote sustainable mobility. Our findings provide valuable insights for developing tailored transportation strategies responsive to New Zealand's diverse traveller needs.
