KEY CONSIDERATIONS
GAP hosts second largest green market in the city and is close to major institutions for Art, Literature, and Botany
Ped volumes drastically increase on the weekend
B41 bus was the 9th busiest bus route citywide and 5th in Brooklyn (2023)
Key bus routes (B41, B69) use the plaza to access broader parts of the city
High number of people commuting under the plaza or accessing subway station at the north
Primary arterials are Eastern Parkway and Flatbush Avenue, accounting for majority of traffic in the plaza
Flatbush Avenue is a key truck route connecting goods and services to the broader city
All severe injuries occurred where Flatbush + Eastern Parkway merge

GRAND ARMY PLAZA TRAFFIC SAFETY PROFILE 2019 - 2023 (5 years) Study area includes Plaza St and central plaza roadways
Key vehicular routes between Flatbush Avenue North and Eastern Pkwy/Flatbush Avenue South accounts for 16% of possible routes through the circle, while accounting for 51% of traffic in the circle.
Most identified issue from survey was the amount of interaction points with vehicles*; GAP currently has:
| Pedestrian Crossings | 31 |
|---|---|
| Bike Crossings | 13 |
| Traffic Signals/Intersection Points | 13 |
*Responses from 2022 Fall/Winter Online Survey with 2077 responses
Lower half of the plaza has higher concentrations of pedestrians and functions as key Brooklyn Cycling hub
