Context of the study
- 37% of everyone working or studying in Copenhagen choose to go by bike
- By 2015 Copenhagen aims to: Increase the percentage of commuters that cycle to
work or education in Copenhagen to 50% Reduce by 50 % the number of seriously injured
cyclists

Purpose of the study
Dual purpose:
- Estimate the health effect of increased commuting by bicycle in and out of Copenhagen Shift commuters from passive to active transport Both positive and negative effects
- Health Impact Assessment as a decision making tool in Danish municipalities Increasing interest in HIA in Denmark Focus on quantification in effect estimation

Main results of effect analysis
- Analyses of different scenarios 50% bicycle commuting:
• Reduction of 17 DALY (1,3%) 50% bicycle commuting + no increase in number of
bicycle accidents:• Reduction of 54 DALY (4,1%)
50% bicycle commuting + no increase in number of accidents + shift of physically inactive commuters:• Reduction of 151 DALY (11,4%)
Very limited effect of air pollution

Conclusion and recommendations
- Shifting commuters to go by bicycle has potential to lower the burden of disease in the population
- Conditions for achieving positive health impacts of bicycle commuting:
Reduce effect of bicycle accidents• Reduce number and severity of accidents
Achieve maximum change in exposure• Shift physically inactive commuters
