This finding from the Union Square Partnership:
The Union Square Partnership analyzes and promotes visitor activity by conducting pedestrian and bicycle counts every two years over several Fridays and Saturdays in July. Working with BFJ Planning, counts were taken from 8 AM to 10 PM at 26 locations around Union Square Park. To gain the most accurate account of how many people move through Union Square on a typical summer day, the data gathered was then combined with transit turnstile information for the 14th Street – Union Square station. The station is the fourth busiest subway hub in NYC on a weekday and skyrockets to second position on weekends. Based on turnstile count patterns, it is estimated that during the summer a record-breaking 383,000 people visit the area on a Greenmarket Friday over a 24-hour period, a 10% increase from our last survey.
