Calculate total AP exposure per person — scenario_pm

Calculate total AP exposure per person based on population and personal travel

Usage

scenario_pm_calculations(dist, trip_scen_sets)

background PM concentration for baseline and all scenarios

total AP exposure per person in the baseline population (for baseline and scenarios)

This function performs the following steps:

the exposure factor rates by activity are defined - these parameters are fixed
calculate pm concentration not related to transport
calculate PM emission factors for each mode by dividing total emissions by distances travelled
calculate PM emissions for each mode in each scenario by multiplying the scenario distance by the emission factors
for modes without any assigned distance, use the PM emissions from the VEHICLE_INVENTORY instead
calculate the total PM concentrations for each scenario
add exposure factors to the trip set by stage mode
add total scenario PM concentrations to the trip set
calculate ventilation rate for each stage taking into account demographic characteristics and exposure factors
calculate the inhaled air and total PM (in micro grams) in the trip set
calculate the amount of time per day spent in sleep, moderate and vigorous activities
add total time spent travelling by each participant to the trip set
calculate ventilation rate for sleep, moderate and vigorous activities
for each participant in the baseline population (with travel component), calculate the total air inhaled, the total PM inhaled and the total PM concentration inhaled for each scenario
assign all participants in the baseline population without travel component, the baseline or scenario PM concentrations
join all people with and without travel in the baseline population
