Background material:
- An article about the assessment, published in Risk Analysis 2004, can be found here: Media:Tainio Gasbus RiskAnalysis 2004.pdf
- Download the model used in the assessment as an Analytica file from here: File:Gasbus model 01.ANA
- If you do not have Analytica installed in your computer, you can get a free trial of Analytica or a free Analytica player for viewing the model from Lumina Decision Systems website
Contents
Scope
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
Scenarios
- Business as usual (current bus fleet)
- All buses converted to modern diesel (EURO3-STD)
- All buses converted to diesel with particle traps
- All buses converted to natural gas buses
Intended users
- Helsinki Metropolitan area council
- Finnish government (e.g. Finnish ministry of social affairs and health)
- Scientific community
- Decision makers at local community level
Participants
- Scientists: KTL, YTV, Joint Research Centre @ European Commission
Definition
Decision variables
Indicators
Other variables
- Variable:PM2.5 emissions from bus traffic
- constant: Bus traffic intensity (if it remains the same)
- Bus fraction of PM2.5 concentration in Helsinki in 2020
- data: total conc. of PM2.5 exposure in Helsinki
- Concentration-response to PM2.5
- Background mortality (for each health outcome)
- Human behaviour (if data available)
