TRAFFIC CALMING A centre line road marking to diagram 1004 should not normally be used between the build-outs of a chicane or pinch point unless the width of each traffic lane so formed would be 3 m or more.

Any yellow waiting restriction lines should follow the line of the kerb around the build-out (see para 21.18).

Chicanes are not normally appropriate places for pedestrians to cross the road as the attention of drivers is likely to be concentrated on negotiating the features. Pedestrians should not therefore be encouraged to cross at such locations, whether by the installation of formal crossings or dropped kerbs. If, however, pedestrians are likely to cross at a chicane, the design should ensure that they can be seen clearly and that they can cross the road safely.

Gateways can be provided to indicate places where the road changes in character, e.g. where a rural road enters a town or village. They must not prevent the passage of any vehicle unless there is an appropriate traffic regulation order.

Edge lines and hatched markings can be used to make the carriageway appear narrower than it is, whilst still allowing larger vehicles to overrun these areas if necessary. The effect will be increased if a central refuge island is provided together with hatched markings, but care must be taken not to increase hazards to cyclists. In rural areas, the width of some farm vehicles needs to be considered and care should be taken not to prevent these or other wide vehicles from passing. If there is insufficient space to accommodate a physical island, a ghost island formed by markings alone can be helpful.

Edge lines and hatched markings should taper in accordance with table 14-1. 130
