Campaigning for Better and Safer Roads



Of 98 full-width humps measured by TMS for the Review of the Scheme, 60 have an average height which exceeds the advertised 75 mm. specification.  The Dept. for Transport recommends that 10% is an appropriate on or off gradient for full width humps.  52 of the 98 have at least one ramp or more, steeper than 10%.  Both of these measurements are critical in terms of safety and can cause severe damage to vehicles and occupants.

Damaged hump

Speed Cushions fared little better if not worse.  Of 54 cushions surveyed, 19 exceed the recommended height.  On/off ramps should not exceed 12.5%.  37 have both ramps too steep and a further 15 have one ramp too steep, making a total of 52 out of 54 having faulty dimensions on just one aspect of their construction.

Broken pavements and roads but pristine humps

Another aspect of humps is the rise in pollution.  The Transport Research Laboratory conducted emission testing on roads with 75 metre hump spacing and found with vehicles travelling at a constant speed, CO emissions increased by 70-80%, Hydro-carbons by 70-100% and CO2 by 50-60%.  The percentages would have increased by up to 200% had the more realistic scenario of braking and accelerating for humps been tested as well, but the more realistic pollution figures could have designated every humps scheme as a serious danger to residents’ health.

More grooves and marks

The speed reduction policies of the last dozen years have been based on speeding causing a third of all road deaths.  Now, the Department for Transport has finally admitted that it can't back it up from real evidence as 5% is nearer the mark than 33%.  When the authorities should have been spending their efforts targeting a small number of reckless drivers travelling excessively fast in dangerous circumstances, they have instead been led by the one third fallacy to criminalise normal progress and to prosecute safe and reasonable behaviour.  (Association of British Drivers)

It is natural to focus on the next hump, rather than notice the child or pedestrian running into the road without looking, which accounted for 9% of all RC2005 accidents.  It has been researched elsewhere, (not RC2005), that 85% of pedestrians involved in an accident have admitted they ran/walked into the road without looking.

Recent information released due to the use of the FoI Act 2000, states that the 7 Gatso cameras in Great Wyrley which were erected at a cost of £350,000, (with yearly maintenance costs of £7,000 making a total of £385,000), reduced average traffic speeds from 30mph to 29mph through the village.  This gave a total reduction in speed of 1mph.  It is also claimed this 1mph reduction in speed gave a 63% reduction in KSI figures.

Recently a high visibility SLOW road safety sign has been removed from the approach to a single-file bridge in Great Wyrley, making the stretch of road far more hazardous.  The precarious and polished states of the road surface is clearly visible on the following pictures.

Travelwise, (Bus Owners Club), said, ‘Humps can have a nasty impact on disabled, elderly or frail people, and those with serious back or neck problems’.  When the Great Wyrley humps were being planned by Safer Routes to School were these well known problems discussed:
Disabled Children           NO
Disabled Residents         NO
Elderly or Frail                NO
Back/Neck problems      NO
Impact on ambulances   NO

As the humps have failed, they will try new pairs of 'moveable humps' to enforce the 20 Zone.

New style humps

'If you break down the 1,900 collisions we have each year, only 3% involve cars that are exceeding the speed limit.  Just 60 accidents per year involve vehicles exceeding the speed limit.  Speed may be a factor in the background but the actual cause of the accident invariably is drink-driving or drug-driving.  In 40 per cent of fatal road accidents in this area one or more of the people involved have drugs in their system’.  (Chief Constable of Durham quoted in the Daily Telegraph, 7th December 2003).

Camera Partnerships: The claims never did hold water....

Gotcha!  Caught on Camera.  Three for the price of one, there was a speed gun in the back window of the van.  A34 near Great Wyrley.
