Greater Greater Washington: “Cycletrack”? “Protected bike lane”? What do you call them?

Those bicycle lanes with a physical barrier between the lane and other road users have been appearing around the region: 15th, L, and M streets NW and 1st Street NE in DC, Hayes Street in Arlington, and Woodglen Drive in White Flint. What should we call these?
