A bench is not a place to sit

Gehl (#9) counted three things on a street: people passing, people standing, people sitting. For years, before he said anything about what a street needs. The Yale and MIT team behind Eyes on the Street (#31) kept the same split when they re-counted Whyte's plaza footage, and the two columns moved differently: walking about 15% faster, lingering roughly halved. …

Kiran Keswani's notes on Russell Market (#35) come with clock times. At the St. Mary's Basilica corner, 1:25 to 2:25 p.m., a tempo stops and pedestrians are left a gap of about 2.5 feet between it and a vendor. At the Broadway corner, 3:00 to 3:15, around 15 autorickshaws wait at the edge and a coconut seller on a bicycle makes a few sales.

Alcantara's Luzon Ave (#27) has the same arrangement at 5:30 a.m.: walkers in the road because vendors hold the pavement. Neither writer calls it a problem. The width of the walkway is whatever is left after everyone else has worked.

Try it: pick a corner, write down the hour, and measure the narrowest gap a walker has to use.

Whyte (#5) filmed New York plazas in 1979-80 and counted who sat where. The Yale and MIT team behind Eyes on the Street (#31) went back with computer vision to footage of four spaces from 2008-10 and found walking about 15% faster, lingering roughly halved, and fewer group encounters. The share of people walking alone barely moved, 67% to 68%. …
