Imagine being able to see the invisible pollution coming from cars, even before you smell it. That’s what researchers at the University of Birmingham are trying to do with virtual reality.
The research targets the main cause behind major health risks and chronic diseases — the pollutants on the road. These unregulated particle pollutants from road, tyres, and brakes can be harmful to the health.
VR Made Pollutant Particles Visible
In the research, detailed computational fluid dynamics models were used to simulate the release of these tiny particles from vehicles. Since these particles cannot be seen with the naked eye, the research made the general public more aware.
The VR models were tested with members of the public in Birmingham city center. “Air quality plays a key role in the health and wellbeing of society,” said the Principal Investigator Dr. Jason Stafford. He added, “Despite the electric vehicle transition, harmful emissions persist through the release of small particles from brakes, tyres and roads, into the air we breathe.”
Dr. Stafford also shared that most bus stops, pedestrian crossings, and cycle lanes are within the danger zones due to them being located near road junctions. The largest pollution dispersions were found here.
The research focused on understanding the pollution pathways and identifying those times when the exposure risk is the highest to people. Using their virtual models, these non-exhaust pollutants can be made visible.
The Bottom Line
People will be able to see the potential dangers with their own eyes and act accordingly to reduce their exposure to these particles. The research published in Royal Society Open Science journal also suggests how implementation of VR could lead to rethinking the city planning for a cleaner air environment.
In conclusion, these research outcomes show the air quality with current town and city layouts. However, redesign and navigation of urban spaces can improve this air quality, particularly where vehicle traffic is unavoidably close to pedestrians and cyclists.
