A CircEUlar member of the UOXF team was invited to share insights on the direct and indirect footprint of digitalisation and participated in a panel discussion on planning urban transport infrastructure to accommodate autonomous mobility systems. This event, organised by the University of Seoul and the Korea Science and Technology Centre, took place from 2-5 December 2024 in Seoul and Incheon, South Korea. The panel featured speakers from various countries, including representatives from Europe, such as the UK and Germany.
The event primarily focused on the application of digital technology in transportation and how such advancements contribute to improved urban development, particularly from a social perspective. Topics included enhancements in quality of life and safety, with a few studies covered as well as economic feasibility assessments (e.g., for MaaS) and environmental implications. The UOXF team provided insights into the broader system boundary of digitalisation, particularly from an energy and environmental perspective. The discussion addressed the impact of infrastructure developments required for implementing autonomous mobility systems and other digital applications, as well as the indirect effects of various digital applications in the transportation sector. The ultimate aim was to identify potential countermeasures to align with net-zero and circular economy targets.
One of the most discussed digital applications in transportation at this conference was autonomous vehicles and real-time communication between vehicles at junctions, potentially eliminating the need for traffic lights. Additionally, there were forward-thinking discussions on redefining vehicles beyond their traditional function; future vehicles could serve as mobile offices or even living spaces, allowing people to work while commuting. This multi-functional approach aligns with circular economy strategies, though its practical implementation remains distant, and the overall environmental impacts are not yet well understood.
The conference also showcased impressive research and development efforts, including various prototypes of autonomous vehicles. However, a critical issue discussed was whether these advancements would evolve as intended. For instance, while autonomous vehicles were expected to improve public transportation by enhancing frequency and safety, particularly during night shifts, and aiding elderly or disabled individuals, current trends indicate a different trajectory. At present, autonomous technology is primarily being integrated into private vehicles, often by younger users. In many cases, this leads to increased travel distances and a shift away from active transportation modes. As summarised by Charlie et al. (2024), the impact on energy use varies significantly, ranging from a reduction of 45% to an increase of 60%.
A key takeaway from discussions was the need for more studies with transparent assumptions and assessment frameworks to evaluate the indirect impacts of digital applications. Participants were surprised by the wide range of reported effects, particularly the indirect effects (e.g., perverse substitution, induced demand) that could offset the intended benefits of the digital technology they developed for the transportation sector and urban development. A deeper understanding is essential to prevent unintended environmental consequences of digitalisation, highlighting the importance of policy interventions in guiding the responsible development and adoption of digital technologies.
Given the increasing role of digitalisation in shaping daily life, its influence on societal transformation toward a net-zero emissions circular economy must be carefully considered.
