On the basis of autonomous developments the number of bicycle transfers per person should have fallen by 5,6% overall over the period 1991-1998. The actual average number of bicycle transfers per person fell by a mere 2%. So obviously something occurred to positively affect bicycle use as well. It is hard to discover exactly what this was, but it is likely something to do with the policies pursued. By no means was this bicycle policy only, but rather overall traffic policy. For instance: irrespective to the type of parking regime, the number of cars has grown strongly and parking has become more difficult. When at the same time better facilities for cyclists and parked bicycles are provided, the relative attraction of bicycle and car may be skewed more towards the bicycle. It is well known that many local authorities actively engaged in this in the nineties. The slight decrease in bicycle use over the period 1991-1998 proves this type of traffic policy/bicycle policy is obviously effective.
