Many people are exposed for short periods to high concentrations of NO2 when

travelling by car, bus, bicycle or on foot. Smaller groups of the population may spend

considerable time in the street environment and thus be heavily exposed to traffic

exhaust, include. NO2. The difference between roadside and urban background is also

of great importance for the selection of control measures. Decreasing the general NO2

in urban background will require emission reductions, whereas improvement of air

quality at roadside may be obtained merely by changing traffic pattern.
