Marginal METS method is based on total physical activity, meaning including sport and commuting exercise, may not include occupation (may be relevant in low income countries).
You need a baseline level of physical activity.
ITHIM did not have Monte Carlo methods as of last year, long-term aim is to introduce.
Regarding the air pollution part, there are 2 main target populations, by which we can mean PM2.5 (which is more dispersed and has many more sources):
An issue with PM2.5 is that it is produced by local stoves, industry, many other things. PM2.5 is not so local. NO2 can become HNO3.
Dose-response functions are in ITHIM. PM2.5 dominates the results in many developing contexts. ITHIM assumes that PM2.5 is a single value per city with a factor of 2 for active transport users.
The best available data varies by place. A key parameter is the % of PM2.5 that is due to local traffic, that would reduce when local traffic. Accra was the one that had most done on it.
Marko's idea was to:
My thinking was to allocate individuals at the OD level and calculate responses accordingly.
Chat to ITHIM guys to look at way to interface.
Age-gender are most important variables.
Baseline level vs new level -> Marginal METs, one way of measuring all physical.
