BACKGROUND Automobile exhaust contains precursors to ozone and fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter; PM2.5), posing health risks. Dependency on car commuting also reduces physical fitness opportunities. OBJECTIVE In this study we sought to quantify benefits from reducing automobile usage for short urban and suburban trips.
