The integration of micromobility and public transport has become essential for addressing urban mobility challenges and reducing environmental impacts. Different forms of incentives are widely recognized as effective tools for engaging new users and encouraging the adoption of sustainable transportation modes in urban areas. However, the effectiveness of incentives varies depending on the mode of transport and the context of application, necessitating further investigation, especially when combining multiple transport modes. This research explores the factors that influence users’ intentions to adopt public transport integrated with micromobility services by providing incentives. Specifically, it examines user preferences for travel purposes, acceptable travel times, and the types and mechanisms of incentives that encourage their participation. Survey responses from 301 participants in Thessaloniki, Greece are collected to understand factors affecting users’ decision to adopt micromobility and public transport in a real-world urban setting. The data are analyzed using descriptive statistics to identify key trends, and an ordinal logistic regression model is developed to evaluate the influence of demographics, travel behaviors, and incentive structures on user adoption. The findings provide insights into the design of tailored incentives and reward mechanisms to promote sustainable mobility. Furthermore, the results have the potential to contribute to the development of mobile applications that enhance accessibility and engagement for all users. These insights aim to support policies and initiatives to support environmentally friendly and cost-effective transportation systems, driving a transition to sustainable urban mobility practices.
