Imperial researchers have designed a unique curved barrier which can protect people from the damaging effects of air pollution.<\/p>\n

With air pollution becoming an increasingly dangerous global health challenge, researchers are constantly working on innovating novel solutions to tackle these 21st century problems. At Imperial College London, researchers are using airflow modeling techniques to study the effects of unique roadside structures to deflect particulates away from pedestrians.<\/p>\n

The health concerns arising from lower air quality are more significant amongst lower income communities which are more likely to be situated near heavily traffic-laden thoroughfares. Similarly, children are both more vulnerable to and more readily exposed to air pollution simply due to their proximity to the ground, where heavier pollutants settle over time. Real-time data on air pollution in London and south east England can be found on London Air, a tool run by the London Air Quality Network at Imperial.<\/p>\n

Dr. Tilly Collins, from Imperial’s Center for Environmental Policy, found this issue particularly worrying, especially after noticing the severe pollution in the air while watching her child playing netball in a school playground alongside a busy London A-road.<\/p>\n

“I thought to myself, what could be done? And done now? So, I started researching the effect of walls along roads,” Dr. Collins said. “It became evident that along the pedestrian side of these roadside walls, there are vortices where the air quality can actually be even worse as the pollutants get trapp<\/a>ed in them.”<\/p>\n

Curved structures help deflect particulates <\/b><\/p>\n

Initially building off simple models, Dr. Collins, Dr. Huw Woodward, also from the Center for Environmental Policy, and Agame<\/a>mnon Otero of Energy Garden, explored ideas of urban design that would mitigate these vortex effects and improve air quality for pedestrians and especially children. They have published their findings in the journal Cities & Health.<\/p>\n

Inspired by airfield baffles and the curved sound-walls alongside motorways in Germany and the Netherlands, the researchers found that curved structures would more effectively disperse and reflect pollutants back towards the roads and would very rapidly improve air quality for pedestrians in an inexpensive manner. <\/p>\n

Although there are challenges in implementing this sort of urban furniture, such as road visibility, the researchers are confident that the net gain in air quality and health is immedia<\/a>te and significant enough to warrant further exploration of these ideas. Beyond air quality, these curved barriers would also mitigate noise pollution, and would be able to act as scaffolds to increase green infrastructure throughout large cities.<\/p>\n

Collaboration is key<\/b><\/p>\n

When asked about the challenges faced during this research project, Dr. Collins said: “Initially, it was difficult to convince others to get on board. The focus is very much on successfully reducing exhaust fumes, but there are these things we can do now to protect our children. The different science<\/a>s, urban designers and architects should collaborate more to design these solutions achieve air quality improvements at local scales more effectively and quickly.”<\/p>\n

Despite the hurdles, Dr. Collins is optimistic for the future of the project. With increased attention being placed on the challenges associated with air pollution, there is a need for unique and effective urban design, and these curved baffling barriers are able to tackle these challenges head on, providing immense benefits to the general<\/a> public.\n <\/p>\n\n
