Smart payment and mobile technologies have created opportunities for Mobility as a Service (MaaS) to become a promising urban transportation solution for future generations. In 2015, The Land Transport Authority of Singapore (LTA) launched a prototype MaaS – an Off-peak Monthly Travel Pass (OMTP). At a price of S$80, the OMTP allows subscribed commuters unlimited free trips on public transport during various off-peak windows. However, the take-up rate has yet to achieve its full potential. Studies suggest status-quo bias is an important reason for the low take-up rate. In our study, we propose examining ways to overcome the status-quo bias in the context of OMTP adoption through field experiments. Building on the findings, we will then enrich the scope of MaaS products beyond OMTP and Adult Monthly Travel Pass (AMTP) to include complementary point-to-point transit options.
