Will it work?

YES!

It’s been done on the continent for years. In the Netherlands, over 60% of residential roads have 18mph speed limits, as a result they are much safer for walking and cycling and many more people enjoy the benefits of being able to get about healthily.

It’s been done in the UK too. Portsmouth is the first city in the UK to have area-wide 20mph limits across the city. As a result of the success of this scheme, Norwich, Oxford, Newcastle, Leicester, Warrington, Bristol and Islington are all introducing similar ones. You may also have read that Brighton & Hove are looking at this too.
