- Abstract : Mobility-as-a-Service (MaaS) is a digital platform that integrates various transport modes, offering users bundled mobility services in exchange for reduced travel costs. However, individuals often have complex travel diaries that include both planned and occasional activities, which can alter their travel plans and make it challenging to predict future travel needs. This study explores how occasional activities influence MaaS subscription preferences and mode choice behaviour. Stated preference experiments were conducted to capture potential MaaS users’ bundle selection and travel mode choice behaviour, and multiple discrete choice models were developed to account for travellers’ responses to uncertainty and loss aversion associated with occasional activities. The results show that, on average, respondents are risk-averse and exhibit diminishing sensitivity to both travel time and cost, with a stronger effect observed for travel time. As uncertainty increases, risk-averse individuals become less inclined to subscribe to MaaS bundles and more willing to pay for flexible travel options such as ride-hailing. We also observe significant heterogeneity in respondents’ risk and loss aversion attitudes, which are influenced by their socio-economic factors. Additionally, correlations between risk aversion and loss aversion were identified, with these relationships varying across both monetary and non-monetary variables.
