Smart mobility apps = smart selections? An analysis of commuters’ mobility choice

Purpose Private vehicle commuters contribute to numerous problems in cities around the world, including traffic congestion, air and noise pollution. Both theoretically and practically, it is assumed that digitalization, in particular the diffusion of smartphones, can help to mitigate these problems. However, there is a large knowledge gap on how the use of a smartphone apps influences people’s daily mobility. To offer new insights into this question, we adopt the S-D logic perspective, which assumes that app users’ mobility choices are based on evaluating the value proposition associated with each of the recommended public transport services and a private vehicle. Design/methodology/approach This study uses a choice-based conjoint analysis (CBC) to derive insights into the relevant choices of consumers of mobility services. Empirical evidence is based on a data collection comprising 634 commuters living in Germany. Findings This study reveals that sustainable transport adoption is significantly influenced by a combination of behavioral, technological, and policy-driven factors. The findings indicate that digital interventions, such as real-time travel information, promote eco-friendly mobility choices. Moreover, infrastructure investments and regulatory incentives play a crucial role in accelerating the transition toward low-emission transport. The study also highlights the disparity in accessibility and affordability of sustainable mobility solutions, emphasizing the need for inclusive policy frameworks. Overall, the research underscores the interconnectedness of technological innovation, policy measures and user behavior in achieving long-term transport sustainability objectives. Research limitations/implications This study advances the theoretical understanding of sustainable transport systems by integrating behavioral decision-making models with environmental policy frameworks. It extends literature by demonstrating how technological innovations and regulatory mechanisms shape mobility choices. The findings challenge conventional cost-benefit models by incorporating social and psychological determinants of transport behavior, emphasizing the role of digitalization in promoting sustainability. Additionally, the study contributes to transport economics by highlighting the dynamic interplay between infrastructure investments and user adoption rates. By refining sustainability assessment methodologies, the research offers a more nuanced perspective on the effectiveness of policy interventions in achieving long-term ecological and social benefits. Practical implications The study provides actionable insights for policymakers, urban planners and transport operators aiming to enhance sustainable mobility. It underscores the importance of integrating digital platforms and incentive-based policies to encourage eco-friendly travel behavior. The findings suggest that targeted subsidies and infrastructure improvements can accelerate the adoption of low-emission transport solutions. Moreover, the research highlights the necessity of user-centric design in public transportation systems to maximize efficiency and accessibility. Social implications This study highlights the societal impact of sustainable transport solutions, emphasizing their role in reducing urban congestion, improving air quality and enhancing public health. By promoting environmentally friendly mobility choices, the findings suggest a shift toward more equitable and inclusive urban transport systems, benefiting marginalized communities with better accessibility. Furthermore, the research underscores the importance of behavioral change in fostering a culture of sustainability, where digital interventions and policy measures encourage long-term adoption of green mobility. Ultimately, the study informs broader societal debates on climate action, social equity and the collective responsibility of individuals and institutions in achieving sustainability goals. Originality/value This study advances our understanding of how commuters can be motivated to use sustainable transport systems. We add new insights into the intrinsic value calculation of everyday users and show the effects of nudging. This study extends existing literature by demonstrating how technological innovations and individual preferences interact to shape mobility choices of commuters.
