Low Traffic Neighbourhoods, or LTNs, reduce traffic in residential streets, and improve access for pedestrians and cyclists with dedicated lanes, wider pavements and planters blocking off vehicle access.
Speed limits of 20mph are designed to reduce the severity of injuries suffered in accidents.
Absolutely. It’s still stupid because this also means that travelling by bus is basically impossible during peak traffic (i.e., when people have to go to work and would maybe consider taking the bus there). That only leaves going by bike, which is not pleasant in bad weather and as soon as you have to leave the city, you need a car
