The Green Line Café in Philadelphia saw a 20% increase in revenue and the Mojo Café in San Francisco experienced a 30% increase. Increased bicycle and pedestrian traffic has been observed in post-analysis at numerous parklet installations. A study by the Great Streets Project in San Francisco indicated increases in foot traffic of up to 37% and increases in the number of people stopping and sitting by 30%.
The Great Streets Project conducted a study in 2011 about the impacts of San Francisco parklets that found generally positive results relating to economics. Liza Pratt, Parklet Impact Study (San Francisco: SF Great Streets Project, 2011).
