Environmental health literacy among urban cyclists: insights from a citizen science study in Ljubljana
This study evaluated environmental health literacy among 205 urban cyclists in Ljubljana, Slovenia, who participated in a two-week citizen science project using personal PM2.5 and noise sensors alongside a custom visualization platform. The researchers integrated the survey data with 10 ride-along interviews, exit field notes, and a mapping workshop with 21 participants to analyze how cyclists interact with exposure data. The intervention increased awareness of environmental stressors, especially noise, but revealed that actual route changes are constrained by safety, convenience, and existing infrastructure.
Why it matters — It demonstrates that providing personal exposure data is insufficient on its own to change commuting behavior, showing instead that individual environmental health literacy must be supported by physical infrastructure like green corridors and car-free routes to enable safer travel choices.
Caveat: The findings are based on a self-selected sample of cyclists in a single European city, which may limit generalizability to cities with different cycling cultures or infrastructure levels.
