At the International Conference of Environmental Psychology (ICEP 2023) in Aarhus (Denmark), Anna Helfers and Lea Fouckhardt from the EMILIA project in the Department of Transportation Planning and Systems (Prof. Dr. Carsten Sommer) presented a field experiment on the influence of ventilation visualization on passengers' risk perception and well-being during the pandemic.

The results show that passengers' risk perception in the vehicle was mainly determined by vehicle occupancy and personal baseline attitudes towards COVID-19, while passengers' well-being was determined by comfort, salience of fresh air, and other passengers' mask compliance. Ventilation visualization had no effect on risk perception and well-being. Implications for communication efforts in the creeping pandemic were discussed.
