Here's a summary of Bristol's progress on 20s Plenty

Here's a summary of Bristol's progress to date. I hope this will
encourage efforts around the country.
It's November 2009 and Bristol has taken another step towards being a
20mph City. Earlier this year the City Council proposed two pilot
20mph areas comprising about 8% of the urban area. The initial proposals
excluded roads where the speed limit would really make a difference and
mainly included narrow residential streets where speeds are already low.
Campaigners made strong objections and now the plans that will go
forward to the formal consultation stage of traffic regulation orders
include most of the streets in the two areas, including most of the
streets that exceed 24mph average speed at present.
While arterial roads are still left at 30mph or higher, the proposals
represent a major success for campaigners and set an important precedent
for going beyond the DfT guideline of limiting the change to 20mph to
streets that already have recorded average speeds of 24mph or less.
Political circumstances have brought this about. The initial proposals
were the initiative of the then ruling Labour controlled council. Local
elections brought a change to Lib Dem control and a new executive with
another energetic executive councillor Dr Jon Rogers became the
executive member responsible for transport. Dr Rogers pushed the 20mph
agenda to new limits by supporting and pursuading highway officers to be
less tentative. The 20's Plenty campaign has had a vital role in
demonstrating public support for the move and making it clear we wanted
"Total Twenty".
Campaigning in Bristol does not stop here. The City Council has
expressed its willingness to look at other areas in Bristol for the
20mph treatment. Even before the first 20mph signs go up Campaigners
will have picked up the baton and be pressing for more of Bristol to be
20mph.
