Anti-Skid
Use of small size road stone which is very hard wearing and is particularly used to deter vehicles from skidding on the approaches to traffic lights, pelican crossings and zebra crossings.  Also used to address ‘loss of control’ accidents, usually at bends on higher speed roads.

Cost (£)
A section of anti-skid surfacing may cost around £5,000.

Bollards
These can be used for various purposes but are normally installed to highlight points where pedestrians may be crossing the road and to deter parking on footways and verges.

Cost (£)
Approximately £300.00 each.

Chicane
This can take the form of a set or various sets of carriageway narrowings.  The narrowing(s) can allow two-way traffic flow or can give priority to drivers travelling in a certain direction (see priority narrowing).  The aim of chicanes is to break up the traffic flow and so reduce vehicle speeds.

Measures such as these can be difficult to achieve as they rely heavily on good visibility from approaching drivers.  The presence of private drives and side roads also restricts opportunities where chicanes can be placed.

Cost (£)
A chicane incorporating two narrowings with associated signing and road markings could cost £12,000.

Coloured Road Surfacing
Can be used in conjunction with road markings to highlight points in the road where vehicle speeds or the occurrence of accidents is of particular concern.  Colours used are normally red or buff but green is sometimes used to highlight cycle lanes.

Coloured surfacing is a deviation from more standard road surfacing and has certain longer term maintenance implications.  With this in mind it is important that it is adopted at strategic locations where it is especially needed and not on a widespread basis.

Cost (£)
A standard area of coloured surfacing would cost approximately £700.00, however, this technique should be used in conjunction with other measures.
