Cars turning right from St. Marks onto Brooklyn tend to drive aggressively & don't always look out for children. Kids often cross here to go to Brooklyn Children's Museum, Brower Park Library, Brower Park.

The short segment on Dean from 5th to Flatbush is a mildly-steep uphill, and the light timing means cyclists nearly always need to stop at Flatbush (posted a comment elsewhere about light timing). The bike lane at Flatbush should be widened to allow for cyclists of different abilities (or assist levels) to resume riding without the risk of collision with another cyclist.

I would really NOT like to have a bike boulevard in this area. I am a longtime user of the B65 bus and would not like to see my access change. I am also a longtime user of the bike lane, as I live on Dean Street and often bike downtown in better weather, and I have not found the roads or access to be dangerous for me, except when there has been construction that has caused issues

This block of Bergen contains multiple businesses on the north side of the street whose patrons & employees engage in frequent double-parking, both for loading/unloading and long-term storage of vehicles (some businesses more than others). The bike lane is on-street (south side) with a wide buffer in this block, and that creates permission for double-parking because vehicles simply swerve into or continuously drive in the bike lane. Instead, the bike lane should be parking protected, preferably with some mild hardening.

When cycling along Dean Street, unless you are waiting for the light to change to green, it's nearly impossible to cross this street before the light changes. Additionally, theres's so much double parking behind the Barclays center, that before you're done crossing Atlantic, you need to look behind you to ensure it's safe to change lanes into the driving lane to avoid whatever obstruction aways you on the other side. I am a strong and seasoned cyclist and I HATE crossing Atlantic. I imagine this would be even more difficult for kids, seniors, novice or nervous cyclists.

The two block-section of Rochester Ave where bikers must go into car traffic to continue east (going from the Dean St bike lane to the one on St Marks Ave) is really dangerous, and always makes me nervous as someone who frequently bikes this way. Cars seem to not expect bikes and are often going much faster than bikers as it's an uphill section. I would love to see some kind of protected lane here or at least better signage to alert cars to bikes.

The road surface on this stretch of Bergen is much rougher, in the bike lane, than in the chevron-painted lane immediately to the left.

The Police and Fire Department continuously park their personal vehicles on the sidewalks and in spaces designated for official police vehicle use. This means that official vehicles (marked & unmarked police cars, for example) frequently park in the bike lane and across the crosswalks when conducting official business. The crosswalks and bike lanes, especially at Bergen & 6th, should be hardened against this. The addition of the plastic delineator between 6th and Flatbush along Bergen has dramatically improved the safety of the bike lane and removed frequent blockages.
