The first parts of Birmingham to get 20mph speed limits in a bid to improve road safety have been revealed.
While 90 per cent of residential roads will be covered by the zones, the main A and B roads will remain as 30mph or 40mph limits.
Council transport bosses had considered three wide areas for the pilot scheme - but parts covering other inner city zones and the city centre will follow in the years ahead.
They ultimately plan to roll out 20mph limits across all of Birmingham over the next few years with support for 20mph limits in Moseley, Kings Heath and Sparkbrook the highest in the city.
According to a report to next week's council cabinet, there were 662 road accidents resulting injuries in the pilot area between 2011 and 2013 - with 897 people injured as a result.
Of these, 314 casualties were on minor roads to be covered by the 20mph limits, with injuries to 314 people, including 26 cyclists and 77 pedestrians, of which 37 were children.
Council cabinet member for transport Tahir Ali said: "The accident figures show that 20 is Plenty is needed for a number of significant reasons.
"Every accident is distressing for the families of those involved so it is only right we look at ways of reducing risk. We cannot sit back and do nothing on this.
"Based on findings from other places that have introduced similar schemes, we forecast there would be fewer accidents per year – and the related economic costs from injures, hospital and ambulance costs would also reduce by £400,000, meaning the scheme would pay for itself in just one year."
Councillors are adopting the pilot scheme to iron out any problems before setting up 20mph limits in further areas.
The cost will cover the installation of new street signs and road marking. Enforcement will remain the same as for the current 30mph limit.
Among those opposed to widespread 20mph is Birmingham's UKIP campaigner Keith Rowe who submitted a petition against last year.
He said: "The council should be trying to increase the flow of traffic and reduce bottlenecks and invest money in trying to get the economy moving. Birmingham is the spiritual home of the motor industry and should be car friendly."
