NEW YORK (PIX11) -- The NYPD put up a sign near 63rd Street and the West Drive looking for witnesses after 58-year-old Jill Tarlov was plowed into and critically injured by bicyclist Jason Marshall.
Police say the 31-year-old saxophone player remained on the scene. It is not clear who had the right-of-way.
Police say Marshall was in the bicycle lane and swerved to avoid hitting other pedestrians.
Witnesses said he yelled for Tarlov to get out of his way but apparently she didn't hear him.
"It's a miracle there aren't more accidents with so many people in close proximity," Madison Reyes, a tour guide and pedicab driver who saw the accident's aftermath.
Cyclists are supposed to slow down at crosswalks and yield to pedestrians, rarely the case, according to some.
"They are always peddling really fast and are very aggressive, Jamecia Forsythe, a pedestrian, told PIX11. "I always get out of their way."
During a two-week period last month, the NYPD issued 4,300 moving violations to cyclists.
Mayor de Blasio's spokesman said after this latest crash, "Making our streets safer means raising the bar for everyone's conduct -- cyclists included -- which is why the NYPD recently conducted Operation Safe Cycle as part of its VIsion Zero enforcement efforts.
And the pro-bicycle Transportation Alternatives added, "The most vulnerable users of our streets, pedestrians, must be safe from reckless cycling. just as they need to be protected from reckless driving. This is particularly true in our parks."
Cyclist Oasis Hawk admitted he often cycles super-fast, but would slow down if he saw more police around.
