Specification of speed cushions in Fen Road
A Freedom of Information request to Cambridgeshire County Council by Neale Upstone
The request was successful.
Neale Upstone
8 October 2008
Dear Sir or Madam,
There has recently been a change from speed bumps to speed cushions
along the route from Green End Road through to Fen Road, due to the
creation of a waste transfer depot in Fen Road.
In two of the locations, the speed cushions are far enough apart
for cars to be able to travel directly between them without any
need to reduce their speed.
In the third location, the cushions are along parked cars, so one
side is never used, causing the waste vehicles to fully use the
opposite side of the road.
The County Council officers involved are aware of these issues, but
so far, direct requests have not resulted in an answer to the
following:
1) What standards are specified, either nationally or by CCC, for
speed cushion design and location?
2) Was an exact location specified for the location of each cushion
(in particular, the distance from the white lines down the centre
of the road) ?
3) Did the contractors put the cushions in the specified location,
or have the contractors installed them incorrectly?
4) Why are there 4 cushions across a 2 lane highway in one of the
locations?
Yours faithfully,
Neale Upstone

Dear Mr Upstone,
Please find below information responding to your recent FOI request.
1) What standards are specified, either nationally or by CCC, for speed
cushion design and location?
A . The speed cushions have been installed in accordance with the
guidance provided by the Traffic Research Laboratory which are in the
public domain at the Department for Transports Website www.dft.gov.uk
<http://www.dft.gov.uk/> / . The statutory instruments we use are
Highways (Road Humps) Regulations 1999
www.opsi.gov.uk/si/si1999/uksi_19991025_... , SI1999/1025
and Highways (Traffic Calming) Regulations 1999 SI1999/1026
www.opsi.gov.uk/si/si1999/19991026.htm , both of which are also
available free of charge on the DfT website.
2) Was an exact location specified for the location of each cushion
(in particular, the distance from the white lines down the centre of
the road) ?
A . The exact location of each cushion was not specified on the
approved drawings, the Inspectors requirement was that the cushions
replaced the existing speed humps, so although the cushions were shown
on the approved drawing exact locations with dimensions from known
locations were not provided. However, within the constraints of the
cushion size, width of road and rational behind the alterations (i.e to
reduce traffic noise) the cushions locations were marked on site.
3) Did the contractors put the cushions in the specified location, or
have the contractors installed them incorrectly?
A . The cushions have been installed in the specified locations.
4) Why are there 4 cushions across a 2 lane highway in one of the
locations?
A . As the size of the speed cushions is defined, the installation of
four cushions was required as the junction of Water Street and
Fallowfield is very wide.

Are you sure that the SI's quoted are the correct ones?
They appear to be about speed humps which according to my understanding are different from speed cushions. Speed cushions should be no more that 80 mm high (but usually specified at 75mm) and should be at least 750mm from the kerb (to allow safe passage for cycles / motor cycles).
