Breathe Easy Thanks to Public Transit

Traffic congested cities suffer not just people stressed out in cars but the exhaust their cars toss into the air. As a result of the use of automobiles asthma and other respiratory issues increase in urban areas, leading to increased health costs and harder lives. This means that if we want people living in cities to breath easy we ought to provide more and better transit options.

A 2002 report [PDF] by the American Public Transit Association pointed out the big difference in the contribution to pollution is that, per passenger mile, public transit produces significantly less pollution than private automobiles: “only 5% as much carbon monoxide, less than 8% as many volatile organic compounds and nearly half as much carbon dioxide and nitrogen oxides.” Studies have shown that children, especially if they are active outdoors in areas with high ozone levels, are more vulnerable to the pollution they inhale.

During the 1996 Atlanta Olympic Games, more public transit was put on to ensure traffic tie-ups wouldn’t delay athletes and fans. Morning rush-hour traffic was reduced by 22.5 per cent. Consequently, daily peak ozone levels dropped by 27.9 per cent. According to a study published in the Journal of the American Medical Association, the number of incidents of children needing medical attention for asthma in that period dropped by 41 to 44 per cent.
