Example of well-designed off-road to on-road transition in Frieburg, Germany.
Good Features:
Projection of kerb forces motor vehicles to move out allowing cyclists to smoothly merge.
Not so Good Features:
Note that use of bicycle path is compulsory so there should be no cyclists on-road prior to the transition and there should be no cyclists on the path beyond the blue sign. Beyond the sign, the path is for pedestrians only.
