No single solution will fit all situations.  Even on the same street different solutions may be required for different sections of the street.  Different portions of a street may have different conditions such as the width of the street, whether there is parking or not, whether there is a sidewalk or drive ways or garbage pickup or any combination of these conditions.  There are portions of streets such as the western end of Rainbow too narrow for a bike lane.  So it is likely that a variety of solutions may be necessary on the same street and from street to street.  Such are the challenges of designing safe bicycle lanes and paths.
