Bikes: Giant OCR C0 road

However, rather than eliminate all bike specific infrastructure, as has been suggested by some vehicular cyclists, I think the solution is to build better bike infrastructure informed by the cardinal principles of vehicular cycling, which are speed positioning and destination positioning.

How do we do this?

Most bike lanes are already located according to the principle of speed positioning, to the right of motor vehicle traffic. There are some locations, such as the segment of the N. Interstate bike lane where Brett was killed, and SW Jefferson west of 14th, which are faster downhill sections. In these areas bike lanes should be eliminated in favor of sharrows or some other treatment.

At intersections with high percentages of right turns across the bike lane, where room is available to do so, such as NW Everett and 16th, a right turn only lane should be provided. This would be possible if the (brand new) curb extension at the SW corner of NW Everett and 16th was eliminated and a few curbside parking spaces were removed. I think the safety of cyclists is more important at locations like this than saving a few steps for pedestrians crossing the street, or the sanctity of curbside parking.
randya, that's me your talk'n about! I am not really a strict VC guy, I run red lights and stop signs whenever I can, for example, but I am a "take the lane" advocate. But I like what you are saying!

Limited use of sharrows and bike lanes based on situational factors, (being mindful of speed and directional lane positions, terrain and parallel parking) could actually move me off of my "just say no to bike lanes" position!

The bike lane reforms like that do in fact address most of my objections to them. I hope that Portland can make such reforms happen.
