And, for in all probability the primary time, odd folks took an interest on this info – what number of automobiles are coming into metropolis centres or how many individuals are gathering in parks was out of the blue straight pertinent to their well being and well-being.

“They were dramatic, off-the-cliff-type changes. Pedestrian footfall fell by 95%, traffic fell to about 40% of normal levels with much reduced peaks.”

Skyscrapers began defining cities within the 19th Century however will they survive the 21st?

Some cities are already serious about how they could change when the pandemic is over. Paris is experimenting with the concept of a 15-minute metropolis – decentralised, mini-hubs the place all the pieces you want is inside a 15-minute stroll or bike trip.

The “ville du quart d’heure” is a key pillar of Mayor Anne Hidalgo’s re-election marketing campaign, turning Paris into a group of ecologically reworked neighbourhoods.

And within the wake of the success of residence working throughout lockdown, corporations are beginning to query the necessity for giant, costly, centrally situated workplaces.

“The skyscraper’s moment may be over.

Whereas observe and hint apps have had blended critiques and success, localised neighbourhood apps that preserve folks knowledgeable about garbage assortment occasions or allow them to assist a sick neighbour have soared in recognition – what Prof Sennet calls a brand new period of “neighbours responsible to strangers”.

When the bustle of busy cities returns, how greatest will we monitor and perceive the behaviour of crowds?

“Using an app to create communication between people is incredibly useful. There has been a lot more use of social apps.

“Sensors cannot inform you why a crowd has gathered. We will change the cop on the nook with a digicam however what are we on the lookout for?”

In San Diego, there are suggestions that smart street lights were used to spy on Black Lives Matter protesters, raising civil liberties questions.

And actually data is pretty dumb, said Prof James. “I can inform you what number of pedestrians are wandering by means of Newcastle metropolis centre however I can not inform you why they determined to try this at this time.

“A smart city has to work with citizens, behavioural scientists, social policy-makers. It shouldn’t just be about data and technology.”
