Birmingham City Council has confirmed its intention to introduce a 20mph limit across 90% of its road network, according to the 20’s Plenty for Us campaign group.
The council, which has more than one million residents, has reportedly said the default should be 20mph and that this should be introduced through limits rather than zones.
According to 20’s Plenty for Us, the 20mph limit will include all residential roads, those with a designated high street function or ‘secondary shopping frontages’, and roads with school entrances or adjacent to schools.
20’s Plenty says the total capital cost of implementing the 20mph limit is estimated at £7m, but adds that “the value of resulting casualty prevention is reported to be £5m per year, based on a conservative estimate in the reduction of collisions at 78”.
Rod King MBE, founder of 20’s Plenty for Us, said: “With Birmingham city and the City of London becoming the latest traffic authorities committing to wide 20mph limits this creates a pivotal moment in enhancing the liveability, safety and active mobility of our communities.
“This is an opportunity for the DfT to recognise that most of it larger cities are rejecting the idea of the 75 year old 30mph ‘national’ limit for urban roads. It’s time to say that 20’s plenty where people, live, work shop and go to school.
“Local authorities are playing their role in this transformation but it could be implemented far more cost effectively if the DfT were to update its signage regulations so that only the exceptions of 30mph and above needed repeater signs.”
