Indicators e.g.
• Mortality of cyclists• Security of pedestrians and runners during nights• No. of swimming pools per inhabitant• Lenght of cyclist’s paths• Another relevant indicators (specific for region,

Social world
• Re-definition of what is acceptable and desirable
Eg. need of environmental changes to enable changes of:

• Obesitogenic index
x
• HD index (Human Development Index)
