We have demonstrated a further refinement of air pollution exposure science that incorporates people’s activity patterns including their route and mode of travel for active transportation trips. We have determined personal exposure without personal monitoring units.
This approach can be extended to all active transportation trips, but will need to incorporate infiltration rates if it were to be applied to motorized travel.
The calculation of exposure that includes mode of travel is particularly important for individuals who commute by active transportation in auto-oriented cities where ambient conditions are elevated. In conclusion, it is possible to calculate personal exposure without personal monitoring units in certain environments, but for a fully integrated full day model it will require additional focus on understanding the parameters controlling localized indoor air pollution.
