From the Brooklyn Paper:
Before installing a bike lane, planners should take this common-sense quiz:
• Does the road have heavy traffic?
• Does the lane fail to get bikers safely to key destinations?
• Is there a lot of through- or two-way traffic that will conflict with the bike lane?
• Is it a busy pedestrian area?
If the answers are “yes” to all of these questions, a bike lane is clearly not appropriate in that location.
