A 20mph speed limit is to be introduced across all residential areas in part of Somerset.
Bath and North East Somerset Council plans to introduce the £500,000 scheme across its area within two years.
Following a short consultation process in each location, signs will be erected and roads marked.
The limit will be introduced first in parts of Bath and larger towns in the area, followed by smaller towns and villages.
The scheme is already in force in places including Lancashire, Oxford, Portsmouth, Liverpool, Manchester and various London boroughs.
