Psychological and Perception Altering Traffic Calming Techniques
I am writing to you to ask if you have any relevant information that may
be of assistance to Sheffield City Council.
Sheffield has been using traditional traffic calming to address its
accident issues for a number of years now. Schemes have been implemented
both on minor residential roads and on residential distributor roads,
which are often bus routes.
The predominant method used has been speed cushions, normally laid in
sets of two or three across the width of the road. Where buses are not
present, road humps have been used. Other features used such as
signing, narrowed carriageways and pedestrian crossings, have also been
successfully incorporated into schemes.
However, the extensive use of vertical traffic calming is not popular
with many people. A number of residential areas in Sheffield comprise
small terraced housing built early in the 20th century. These properties
have few off highway parking places. In order to ensure the correct
vehicle alignment at cushion sets, parking restrictions are put in. This
can have the effect of removing one third of on-street parking
opportunity.
Additionally, there are complaints that speed cushions damage car
suspension and are painful for people with pre-existing back injuries.
Noise is also cited as a problem at some locations where traffic
contains a reasonable proportion of heavy goods vehicles.
The City Council is keen to move away from these traditional methods,
particularly, on low trafficked roads and would like to use other
innovative methods that are based on altering driver behaviour through
perception.
I have found little internet based evidence of such techniques but I
believe that other authorities and institutions have considered, and
maybe, have used alternative forms of calming. I would be keen to learn
of any work or research that you have carried out in this field.
I would be grateful if you could spare some time to contact me. I
appreciate that you are busy, but any information or guidance would be
gratefully received.
Yours faithfully
