Traffic Calming
Traffic calming can be accomplished by installing road humps, speed cushions, raised junction plateaux, chicanes, road narrowing, road closures. The use of each of these features on any road on will depend on a detailed assessment of such things as use of the road, whether it is a main road or residential road, on-street parking, bus route, emergency services route etc.
If you would like to report a junction which you feel is dangerous, or if you feel speed restriction measures need to be implemented on a certain road, please use the form below.
There are regulations governing the layout of speed control
humps. There must be a form of "slowing feature" - usually
formed by a change of priority (traffic entering the
system has to turn sharp left or right into the road, or has
to "give way"). Sometimes mini roundabouts are used at the
start of a system of humps.
The shape of the speed control humps are strictly
regulated. They must be between 50mm and 100mm high, at least
2.75m long and extend over the full width of the road, except for a
drainage channel at either end. They may have either flat
tops or round tops. Many local authorities have adopted the
85mm high hump as standard. This is becasue it has been found
to reduce traffic to around 20 mph. The 100mm high humps
reduce speeds to 17 mph on the hump but speeds rise to 35 mph
between the humps, causing excessive acceleration, braking and
increased pollution. Flat topped humps can be of any length
and are oten known as "speed tables". They are sometimes used
to reduce the impact on long wheel base vehicles such as
buses. The Council favours the use of speed platforms because
they minimise adverse effects on the occupants of vehicles who are
driving at sensible speeds.
Speed control humps can lead to complaints about increased noise and sometimes increased vibration from traffic. They have however been proved to reduce traffic speed and they have been installed in many locations.
