# British Road Signage (Kinneir & Calvert)

> The national sign system Jock Kinneir and Margaret Calvert designed for Britain's motorways, first used on the Preston By-pass in 1958, and through the Worboys Committee for all roads from 1 January 1965. Place names are set in mixed case in their Transport lettering, spaced on tiles measured in stroke widths. Colour codes the road (blue motorway, green primary with yellow numbers, white local, brown for tourism from the mid-1980s), red triangles warn and circles command with Calvert's pictograms, and junctions are drawn as maps: a kit of parts written into law.

- Period: 1958–present
- Where: Western Europe
- Origin: Britain: the Ministry of Transport's advisory committee on motorway signs, formed in 1957 under Sir Colin Anderson of P&O with T. G. Usborne, head of the Ministry's Traffic Signs Division, joining it in its final months (he went on to chair the Worboys working party), commissioned Jock Kinneir, who brought in his former Chelsea student Margaret Calvert as assistant. Their signs first appeared on the Preston By-pass (opened by Harold Macmillan on 5 December 1958, now part of the M6) and were revised a year later for the M1. Two 1961 articles by the designer Herbert Spencer preceded the Worboys Committee, chaired by Sir Walter Worboys of ICI, with Kinneir as consultant; its report (July 1963) carried the system to all roads on the Continental model of the 1949 UN Protocol, and the Traffic Signs Regulations and General Directions 1964 brought it into force on 1 January 1965. Kinneir made Calvert a partner in 1964 (Kinneir Calvert Associates). Revised by the 1994 regulations and the Guildford Rules (LTN 1/94) and now prescribed by TSRGD 2016, the system still signs UK roads, and its Transport lettering is also used in Ireland, Iceland, Portugal, Greece, Hong Kong and elsewhere
- Branch: Rational modernism
- Also known as: Kinneir Calvert road signs, Worboys signs, Transport-lettered signage, UK traffic sign system

## Use it with care

These signs carry legal force: the Traffic Signs Regulations and General Directions prescribe them, so borrow the method (mixed case, colour and shape codes, a kit of parts) but never make a look-alike that a road user could take for a real traffic sign. The lettering is licensed too: GDS Transport is reserved for GOV.UK services, and New Transport is a commercial typeface from A2-Type.

## How it works

- Set destinations in mixed case, an initial capital then lower case, so that names are read as word shapes at speed and distance, in a medium weight for white or yellow letters on dark signs and a heavier one for black letters on white; keep capitals for the few regional destinations such as 'The NORTH'.
- Colour-code the road, not the message: white on blue for motorways, white on dark green with yellow route numbers for primary routes, black on white for other roads, white on brown for tourist destinations, and show the status of a route reached from the junction ahead with a panel or patch in its own colour.
- Let shape give the order before any word is read: a red triangle warns, a red ring prohibits, a blue disc instructs and a rectangle informs, and each holds a flat pictogram (a black silhouette on white inside the warning triangle) instead of a sentence.
- Draw the junction as a map: a route symbol shaped like the junction, arms whose width states the road's status (6 stroke widths for motorways and primary routes, 4 or 2.5 for others) and destinations grouped beside each arm.
- Sign every junction as a sequence aimed at the driver: advance direction signs on the approach, direction signs at the junction and route confirmatory signs after it, with motorway junctions signed three times.
- Supply a kit of parts and the rules for using it instead of finished layouts: letters on tiles, every gap measured in stroke widths of a quarter of the x-height, and the x-height chosen by the speed of approaching traffic, so that any contractor builds the same sign.
