Smarter cycling, safer cycling? Acceptance of advanced cyclist assistance systems in 19 European countries

As cycling grows in popularity as a sustainable transport mode in Europe, cyclist safety has become a priority. Advanced Cyclist Assistance Systems (ACAS), inspired by Advanced Driver Assistance Systems (ADAS), offer potential safety improvements but remain underexplored. This study examines ACAS acceptance among 5,991 cyclists from 19 European countries, focusing on public perceptions and adoption drivers. Participants evaluated various ACAS types-crash prevention, visibility enhancement, environmental monitoring, and post-crash assistance-based on safety, usability, and reliability. Acceptance varied across countries, with higher rates in areas with strong cycling infrastructure. Safety and reliability were universally valued, though gender differences emerged: women prioritised safety and visibility, while men favoured usability and added features. The findings highlight the importance of infrastructure, reliable technology, and awareness efforts to promote adoption. Policymakers and developers can use these insights to tailor ACAS innovations, ultimately enhancing cycling safety and supporting the broader development of smart, cyclist-focused technologies.
