A key issue in transport provision is how to determine where investment in a network’s service can be most effective, given a budget that does not allow all the investments desired. Methodologically this can also be an issue, as often there are a myriad of options available - too many for the customer to easily trade-off, and too many for traditional approaches such as conjoint analysis. Using both a non-parametric approach and the indices approach advocated by Swanson, Ampt and Jones (1997), 600 rail passengers are examined across 15 alternative scenarios, to derive customer preferences for proposed changes to the Auckland Rail network through evaluation of their affect (liking) for the scenarios and likely resultant behaviour. Fisher’s (1974) environmental quality scale is used to assess customer affect. (a) For the covering entry of this conference, please see ITRD abstract no. E211825.
