Update on Prospect Park Traffic Patterns
The NYC Department of Transportation (DOT) has completed the new lane configuration for the Park Drives, which is now in effect. As part of the Road Sharing Taskforce recommendations, DOT has determined that pedestrian activated push buttons can be installed at all traffic signals in the Park. DOT has already begun installing and activating the push buttons on the West Drive, including at the 2nd, 3rd, 9th and 12th Street crossings. DOT anticipates that push buttons will be installed and operational around the entire Park in the next few weeks.
Here's what you need to know:
Pedestrian-activated traffic signals will only work when that portion of the Park Drive is closed to motor vehicles.
When the Drive is closed to motor vehicles, the traffic signals will remain green and pedestrian signals will display the steady hand symbol (Don't Walk) until a pedestrian activates the button.
When the Drive is open to motor vehicles (7 a.m. to 9 a.m. on the East Drive and 5 p.m. to 7 p.m. on the West Drive, Monday through Friday), the traffic signals will operate using the regular green/yellow/red phases to facilitate traffic flow.
In addition, on June 25, DOT will permanently close the vehicle entrance at Parkside and Ocean Avenues. To access the Park Drive during morning rush hour (7 a.m. to 9 a.m. on the East Drive), vehicles must enter at Park Circle.
