**Birmingham, UK** – A new study published in the *Royal Society Open Science* journal reveals that a virtual reality (VR) experience could be key to raising public awareness about the hidden dangers of non-exhaust vehicle emissions. This research, led by the University of Birmingham, focuses on particulate matter released from brakes, tires, and roads, which can contribute to major health risks and chronic diseases.
The study utilizes detailed computational fluid dynamics models to simulate the dispersion of these invisible particles. Through immersive VR experiences, the public, policymakers, and city planners can visualize the pollutants and understand how they impact urban spaces.
The VR models were tested in Birmingham city center, the UK’s second-largest city and a major contributor to PM2.5 emissions from brake and tire wear. Participants were able to experience the pollutants firsthand, revealing the dangers of areas like bus stops, pedestrian crossings, and cycle lanes, which often fall within the high-pollution zones created by braking vehicles.
Dr. Jason Stafford, the study’s lead researcher, emphasizes the importance of understanding these pollution pathways, particularly in the context of the electric vehicle transition. “Despite the shift to electric vehicles, harmful emissions persist through the release of small particles,” he explains. “Our VR models show how these pollutants are dispersed and help people understand when and where exposure risk is highest.”
The research suggests that the implementation of VR could significantly influence city planning. The study highlights the need for redesigning urban spaces to prioritize cleaner air, especially in areas where vehicle traffic is close to pedestrians and cyclists.
“This research not only exposes the air quality issues with current city layouts, but also offers potential solutions for creating safer and healthier urban environments,” says Dr. Stafford. “By making these invisible pollutants visible, we can empower people to make informed choices and encourage city planners to prioritize cleaner air in their designs.”
