With climate change, weather has emerged as an important health issue. While various studies demonstrate profound effects of weather on walking and cycling, limited attention has been paid to subjective weather experiences and the psychological mechanisms that may (partially) underlie these effects. This project integrates theoretical insights on thermal comfort, and weather and emotional experiences in the context of physical active travel behaviour. To that purpose an unique panel travel diary data for 945 Greater Rotterdam respondents (The Netherlands) has been used.
