| |
| − | Purpose
| |
| − |
| |
| − | To compare PM2.5 induced mortality in alternative public bus-transportation strategies as being considered by the Helsinki Metropolitan area.
| |
| − |
| |
| − | Boundaries
| |
| − |
| |
| − | *area: Helsinki Metropolitan area, Finland
| |
| − | *population: whole population in Helsinki area (1 million)
| |
| − | *primary PM2.5
| |
| − | *time period: Based on data 1996-1997, projected to year 2020
| |
| − | *Public Health effects: Mortality due to cardiopulmonary diseases, lung cancer and other non-accidental causes (?)
| |
| − | *Bus traffic tail-pipe emissions
| |
| − | *different ratio between the technologies
| |
| − | *fuel

| − | #Business as usual (current bus fleet)
| |
| − | #All buses converted to modern diesel (EURO3-STD)
| |
| − | #All buses converted to diesel with particle traps

| |
| − | Variables
| |
| − | *Decision variable: Which bus engine?
| |
| − | **includes emissions from different engine types
| |
| − | *PM2.5 emission from bus traffic
| |
| − | *PM2.5 concentration of bus traffic in Helsinki area (= exposure and intake estimate)
| |
| − | **data: total conc. of PM2.5 exposure in Helsinki
| |
| − | *constant: Bus traffic intensity (if it remains the same)
| |
| − | *Dose-response
| |
| − | **slope uncertain à variable
| |
| − | **background mortality included as a constant
| |
| − | *human behavior (if data available)
| |
| − | *Health impact à mortality rate
