Berkeley could become North America’s first major city to build a comprehensive Dutch-style cycle-track network. For the past two years, city staff has been developing a new Bike Plan, which is set to go before City Council in December. The plan would revolutionize cycling in a town with an already respectable bike mode-share. If approved, the plan would prioritize the construction of new cycle-tracks in the south campus area, and convert a downtown segment of Milvia into a cycle-track.
The plan also calls for cycle-tracks on the major arterials , including Claremont, Telegraph, Shattuck, University, and Adeline. Each those projects would have to go through a “multi-modal” corridor study. Berkeley staff says these studies are needed to accommodate other road users (buses, pedestrians, and automobiles). Hopefully, the studies will not used to sandbag the bike plan…
Systemic Failure 
What is the difference between a cycle track (4a) and cycle track (4b)?
If I understand the key correctly, 4a is an existing ccycletrack facility and 4b is proposed.
From http://www.bikeberkeley.com/wp-content/uploads/2015/02/3.-Existing-Conditions_reduced.pdf:
Class IVA: One-way cycletrack/ protected bikeway;0 miles (in Berkeley)
Class IVB: Two-way cycletrack/ protected bikeway;0 miles (in Berkeley)
What’s the difference between Class IA (paved path) and Class IVB (2-way cycle track)? In the PDF, both types are adjacent to the road, separated by plants.
The main difference seems to be that Class I allows pedestrians. So an adjacent sidewalk is not part of Class IV, but an adjacent pedestrian lane *IS* part of Class I. Is that it?
That’s the difference. Class 1 is a multi-use trail, often considered a separate way than a street, and Class 4 is a cycle track (“protected bike lane in much of the country”) that’s part of the street.

Thanks Steven, but that seems like a distinction without much of a difference. They’re both physically separated. Why do we need a whole ‘nother class for that? A two-way bikeway could be classified either way.
One-way cycle tracks (on each side of the road) I understand. That’s truly a new thing compared to Class I and II.
[…] Berkeley’s revolutionary new bike plan (Systemic Failure) […]
This is exciting; however, Seattle also has an exciting bike plan that would revolutionize cycling in the city. Unfortunately, it’s underfunded and the downtown portion of it is being delayed indefinitely. I’ll be more excited (and possibly move there) if Berkeley actually manages to build this stuff.
