20's Plenty for Crosby

Facts & Briefings

Fact sheets and briefing are available on a wide range of topics connected with 20mph limits on our national site at www.20splentyforus.org.uk/briefings.htm

The Department of Transport reviewed and republished its guidance on Setting Local Speed Limits, Circular 01/06. This placed the responsibility for setting speed limits very clearly with the local authorities.

This change was the trigger for the move towards 20mph limits being set as the default for residential roads when Portsmouth became the first city in 2008 to fully implement a city-wide scheme. For a cost of just £475,000 it changed the speed limit on 1,200 roads to 20mph.

No more Speed Bumps

20 mph limit areas do not need traffic calming measures - just a change of signage. The wider you expand the default 20mph area the more cost effective it becomes as you don't need so many signs.

Slower journeys?

It actually makes journeys quicker as traffic flows more freely. How much time do you spend waiting at junctions watching gaps in the traffic that could be used if approaching traffic was travelling more slowly? How often do cars race away from the lights simply to bunch up and wait at the next set of lights?

Will the Police Enforce it?

Merseyside Police have already been approached by residents on Eshe Road about speeding. Their speed cameras will work for 20mph. However the most effective enforcers of 20mph are you. If enough people respect the speed limit the rest will have to literally follow on behind.

It Reduces Pollution and fuel use

With no speed bumps and slower speeds journeys will be more efficient and pollution reduced. There is a whole section on the 20 is Plenty website dealing with the technical facts on engines, gears and emissions for those who feel that 20mph is 'between gears'.

What about the cost?

In 2009 according to the Office of National Statistics as part of the national costs road casualities cost Sefton £42 Million and physical inactivity costs were £64 million. The savings of intoducing 20mph seem pretty clear. See "Briefings' on the main 20 is Plenty site.

Safety for Us all

Drivers are twice as likely to kill someone when travelling at 35mph than they are at 30mph. At 40mph, nine out of 10 pedestrians will die, but at 20mph, nine out of ten will survive.
