Last January a Roosevelt Island resident asked:

… do you have any updates on the speed bumps.? A few days ago I was walking
on the sidewalk near 540 next to the pet store. Someone sped out of the Side
of the building and almost hit me. Today just about 30 minutes ago a older man
walking across the street near the elementary school was almost hit. When he
confronted the driver and asked him to be careful the driver got out of the
car and yelled at the elderly man. This issue needs to be corrected. Speed
bumps and give tickets. I have seen public safety give numerous tickets for
illegal u turns but never saw them stop people speeding or running through
stop signs.

Last March, another resident tweeted:

At least one speed cushion was in place on the East Loop Road near the Cornell Tech campus today. However, for some reason the Roosevelt Island Operating Corp (RIOC) placed the speed cushion in the bicycle lane, apparently to slow down speeding bikes,

and not in the car lane to slow down cars.

Here’s the March 15 Roosevelt Island Residents Association Public Safety Committee meeting discussion about speed cushions with RIOC Public Safety Department Chief Kevin Brown.
