Traffic is the single biggest contributor to outdoor air pollution. As much as three-quarters of traffic emissions come from short journeys in and around cities. We have the solution to this pollution problem. Shift citizens from car dependency to active transportation. The benefits are big.

Cities have the power, through changes and investment in mobility infrastructures, to calm traffic, clear the air, and generally improve city dwellers’ health and well-being. By:

• Building bike paths and pedestrian safety improvements
• creating dedicated bus lanes, a switch to battery-powered electric buses, and/or innovative new approaches to public transport
• discouraging car use and creating car-free downtown core areas 

Planners encourage active transport rather than perpetual traffic jams!

As urban populations grow, land becomes ever more precious. Designing streets for people rather than vehicles is one of the ways cities can reduce sprawl, emissions, traffic, and pollution, leaving the way open for improved health, more access and interaction with nature, and clearer, cleaner air.
