A Stated Preference Experiments for Mobility-as-a-Service Plans

As the Mobility as a Service (MaaS) concept gains wider acceptance, there is increased demand for understanding more about MaaS subscription plans. This paper presents the design of a stated preference (SP) experiment that captures the complex decision making process of purchasing MaaS products. It uses a prompted recall smartphone based travel survey tool that is expanded by a SP experiment regarding MaaS plan choices. Respondents are presented with repeated choices between four hypothetical MaaS plans out of which three are fixed plans and one is a menu option. This approach allows for testing people's preferences and willingness to pay for flexibility. The attributes of the plans include transport modes and amounts, mode specific features (e.g. 10-minute taxi guarantee), transferability (meaning how much of left over mode-attributes can be transferred to the next month), special prizes (e.g. a free dinner for two) and the price of the plan.
