Summary:

- The article discusses the use of virtual reality (VR) to study the interactions between pedestrians, cyclists, and air pollutants in urban environments.
- Researchers have developed a VR simulation that allows them to track the movement and exposure of participants to air pollutants, providing insights into how urban design and infrastructure can impact pedestrian and cyclist safety and exposure to harmful pollutants.
- The study aims to help urban planners and policymakers make more informed decisions about urban design and transportation policies to promote active and sustainable modes of transportation while minimizing the health risks associated with air pollution.
