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?
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/ . The statutory instruments we use are
Highways (Road Humps) Regulations 1999
www.opsi.gov.uk/si/si1999/uksi_19991025_en.pdf , 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
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
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.
