Identifying Consumer Segments for Advanced Driver Assistance Systems (ADAS): A Cluster Analysis of Driver Behavior and Preferences

Publication Name: Future Transportation

Publication Date: 2025-12-01

Volume: 5

Issue: 4

Page Range: Unknown

Description:

The rapid advancement of Advanced Driver Assistance Systems (ADAS) is reshaping the future of mobility by offering potential improvements in safety, efficiency, and driving experience, yet consumer acceptance remains uneven across regions. This study addresses the gap in knowledge and trust by examining how Hungarian drivers, as part of the Central and Eastern European context, perceive and adopt ADAS technologies. To achieve this, we conducted two expert in-depth interviews to refine the research instrument, followed by an online survey of 179 drivers. Using k-means cluster analysis, we identified three distinct consumer segments: Conservative Controllers, who demonstrate low levels of trust and willingness to adopt ADAS; Cautious Adopters, who weigh costs and benefits carefully; and Pragmatic Innovators, who are open to experimentation and display the highest acceptance and willingness to pay. The results reveal that awareness and familiarity strongly influence acceptance, highlighting the role of consumer education and transparent communication in shaping adoption. The findings suggest that manufacturers, driving schools, and policymakers can accelerate the diffusion of ADAS by developing targeted strategies tailored to different consumer groups. Strengthening knowledge and trust in these systems will not only support their market success but also contribute to safer, more sustainable transportation.

User Acceptance of Advanced Driver Assistance Systems (ADAS) and Their Implications for Urban Mobility: Evidence from Focus Groups in Hungary

Publication Name: Urban Science

Publication Date: 2026-05-01

Volume: 10

Issue: 5

Page Range: Unknown

Description:

Advanced Driver Assistance Systems (ADAS) are increasingly shaping urban mobility and road safety, yet their benefits depend not only on technical performance, but also on driver acceptance. This study examines how Hungarian drivers perceive and evaluate key ADAS functions, Adaptive Cruise Control (ACC), Lane Keeping/Centering Assist (LKA/LCA), and Forward Cross Traffic Alert (FCTA), in urban driving contexts. The research is based on qualitative focus group discussions conducted in Győr, Hungary, involving drivers aged 20–50 from different age cohorts. Data were analyzed using thematic analysis. The findings show that the acceptance of ADAS is strongly context-dependent and function specific. ACC was perceived primarily as a comfort-enhancing tool, especially on longer or more monotonous routes, while LCA was often regarded intrusive and less reliable in urban conditions due to poor road markings, potholes, and frequent stop-and-go situations. On the contrary, blind spot and cross-traffic-related functions were evaluated more positively due to their direct safety benefits. Trust, perceived risk, and control emerged as key dimensions of acceptance, with many participants emphasising the importance of warning-based support rather than a strong autonomous intervention. In general, the study concludes that urban acceptance of ADAS is shaped by the interaction of infrastructure conditions, perceived usefulness, and driver trust, highlighting the need for more transparent, context sensitive, and user-centered system design in support of safer urban mobility.

Infrastructure-led urban development does not have to come at the expense of environmental sustainability: Evidence from South Korea

Publication Name: Cities

Publication Date: 2026-10-01

Volume: 177

Page Range: Unknown

Description:

This study examines the interplay between large-scale rail infrastructure expansion and long-term vegetation dynamics in the Seoul Metropolitan Area, highlighting how integrated urban planning can mitigate or even reverse environmental degradation typically associated with rapid urbanization. Uniquely, Korea's new towns have been systematically developed as transit-oriented districts to alleviate the hyper-concentration of population in Seoul, resulting in a context where railway construction and urban growth are tightly coupled. Contrary to the prevalent narrative of inevitable green space loss, the spatial analysis reveals that several newly developed districts, designed with explicit ecological considerations, demonstrate stable or even increasing vegetation indices over the study period. By employing a combined Geographically and Temporally Weighted Regression framework, we identify localized trajectories where synchronized transit investments and proactive green urbanism policies have yielded net ecological gains. These findings position Korea's policy-driven urban model as an instructive case study for reconciling infrastructure development with ecological resilience, underscoring the critical importance of integrating environmental objectives into transportation and land-use planning.
