About the 20mph scheme

How long will it take/when will it happen?

It will take approximately 4 years to complete.  The city has been divided into 7 areas and these have been prioritised based on the number of collisions.  It will include almost all residential roads; however the exact roads are not yet available and will of course be subject to consultation. 

What is the cost and how is it being paid for (I thought the council had no money)?

It will be £1.65m over 4 years. The works are being funded partly through Liverpool City Council and the Liverpool Primary Care Trust.

How will I be consulted?

All residents within their specific area will be fully consulted on the scheme before the scheme starts on site. This will be done either through letter drops, engagement days, exhibitions, publicity campaigns etc etc.

Will it include traffic calming/road humps?

No, there are no road humps to be introduced as part of this scheme.  This scheme involves introducing 20mph speed limit signs in residential roads across the city.

Why are we doing this?

It's about improving road safety by reducing speeds; this will create a safer environment for members of the public living and visiting these areas.

Reducing the speed of vehicles will in turn reduce the number and severity of accidents.  Over the last 3 years there have been over 5000 casualties on our roads and 500 people killed or seriously injured.

Under the proposals it is calculated that there could potentially be a total reduction of 54 collisions a year in the proposed 20mph speed limit areas. This would present a saving to society of over £5.2m a year.

Are people likely to obey the 20mph signs if there’s no speed humps?

We are hoping that people will want to be good, responsible citizens and play their part in improving road safety.

This intervention relies on a collective sense of social responsibility and a change in public thinking. The 2010 British Social Attitudes Survey found that 71% of participants were in favour of 20mph speed limits in residential areas.

Surely it’s careless people who cause accidents, why should everyone else be forced to drive slower?

A pedestrian has a 50% chance of surviving after being hit by a car at 30mph compared to a 90% chance of surviving if hit at 20mph.

Are the police going to enforce it/stop people?

The police welcome any reduction in speed which may reduce the number of people killed or seriously injured on our roads.

Will it make car journeys longer?

If you were able to travel constantly at 30mph then travelling at 20mph would make the journey time longer. However in reality it is very rare that people travel at a constant speed of 30mph in residential areas. Many obstacles cause people to slow down or stop many times on a journey – junctions, traffic lights, cars turning, parked cars, bends, pedestrian crossings, volume of traffic etc.

This means that only a small part of your journey on these roads is spent driving along at the maximum speed limit (about 20% of the time). Therefore the likely increase is small – ranging from about 40 seconds to a couple of minutes at the most.

Has this been done elsewhere, and if so, what were the results?

  • Portsmouth – covered most residential roads (94% of the road length). This resulted in a 22% reduction in casualties and an average speed reduction of 1.3mph.
  • Warrington – 3 pilot areas.  Reduction in casualties of 27%, with an average speed reduction of 1.5mph.
  • Edinburgh - It contains roughly 79km of streets, of which 20km are covered by existing 20mph zones or other traffic calming and 40km  would be subject to the new limit. It is proposed to leave 19km of major or  Secondary Roads with a 30mph limit.
  • Newcastle – Pilot across 4 area’s.  Saw a reduction in average speed of  1.1mph.  18% reduction in accidents.
  • Wirral – have proposals similar to our own – not progressed yet.     Sefton – Area split into 135 cells, will only complete a few a year.
