Anyone besides me think this is far too complicated?
[Complications will cause more violations (and less safety) compared with a simpler system.]
Hypothesis: to increase safety, anything that is optional or advisory ought to be eliminated.
Bikes are either allowed (in which case they should be respected) or prohibited (like freeways, in which case they should be ticketed).
Cars are either allowed (in which case they should be respected) or prohibited (like exclusive bike lanes, in which case they should be ticketed). Transitions from prohibited to allowed and allowed to prohibited should be clearly marked.
4 types of lanes:
|Cars allowed||Cars prohibited|
|Bikes allowed||Shared lane
|Exclusive bike lane
[marked or signed as such]
|Bikes prohibited||Exclusive motorized lane||Not a road|
From what I can tell there are at least 5 shared lane markings: Green bike lanes, Advisory bike lanes, Sharrows, Bike Blvd, and Green shared lanes. There are at least 3 exclusive lane markings: Bike lanes, Cycle track, buffered bike lanes. This should be reduced to one exclusive marking (a bicycle symbol [maybe on a green pavement] with solid white lines). Buffers (no car) areas are standard markings that have no special meaning here. Some transitionary marking indicating the beginning and end of an exclusive bike lane can be used.
