London's Low Traffic Neighborhoods (2020s)
London began rolling out low-traffic neighborhoods in 2020, using bollards and planters to block cut-through traffic. Over 70 LTNs were implemented, reducing traffic inside neighborhoods by up to 47%.
Traffic dropped and cycling increased, but some boundary roads saw temporary congestion.
LTNs became a permanent feature of London's streets, though debates over equity and access continue.
NYC's plan explicitly borrows from London's model, and the Driggs Avenue project is an early test of similar tactics.
