Nine new 20mph zones in Leicester have been approved - but much of the funding still has to be found.
Eight of the schemes are near schools and seven include traffic calming measures such as speed bumps.
They range in size from a single road - Sandhurst in Newfoundpool - to 44 streets around Harrison Road.
The city council has a £100,000 annual budget for the works but said it would seek developer funding to help with the estimated £850,000 cost.
Other zones include 17 roads in the Aylestone village area, 11 in Humberstone Village and 21 in Bradgate Heights.
Three schemes will focus specifically on school areas, including 12 roads around St Mary's Fields Infants School in Rowley Fields, 15 around Woodstock Primary School in Beaumont Leys, and 24 around Mowmacre Hill Primary School area.
A council spokesman said: "It is hoped the 20mph zones will lead to fewer, less severe road traffic accidents, and encourage more cycling or walking.
"Residents in each of the areas were involved in the design of the schemes, and strongly supported the proposed ideas."
