New York City Bike Lane and Mixing Zone (Left Turn)

The following photos show the striping for the left side bike lane where there is on-street parking that is removed to make room for an exclusive left turn lane. To maintain as much parking as possible the amount of length for the left turn lane is kept to a minimum. The vehicles are presented with the teeth to indicate yield on entry. The green bike lane marking is dropped at this same point to indicate shared space with the traffic and sharrows are used in this space.

The second photos shows the Turning Vehicles Yield to Bicycles sign, which is in the MUTCD specifically for pedestrians, but it makes sense to call out bicycle traffic at this location because you have a left turn lane that conflicts with the left side bike lane.

The farside of the intersection is where I think NYC has offered the greatest innovation. The provision of the curbing for a pedestrian refuge presents an opportunity for yielding between the person on a bicycle and reducing the amount of time (potentially) that is necessary for the pedestrian clearance. To reduce the total time for the intersection, you'd have to do something on the nearside.

Peter, do you know how they handle right turns?

Nevermind...that's what I get for reading top to bottom

What do you think of the transition across three lanes? I would have a heard time with three lanes, but with low pedestrian compliance it complicates the situation.
