Creating and testing design variants
Finding a research-led design solution for Ireland’s dual-language road signs - a brief design journey.
World Tour
I first created many sketch sign layouts using commonly used typefaces which fitted the criteria of high x-height and suitability for signs. These rough tests were created to explore colour differentiation and compare this with other ways of differentiating the languages including weight difference, uppercase and italics.

National Identity
Are there implications of road sign design for national identity?
Intentionally designing style attributes into road sign types is contrary to best practise, the focus must remain on clarity. But it is notable that motorway signs become a visible expression of national identity. I would argue that this even more the case in countries with dual-language signs. Margaret Calvert, co-designer of Transport mentions this unintentional by-product in relation to the design of the UK’s signs…

Signs are getting bigger

At the outset of this design research project, I speculated that in the future Irish roadsigns may need to be redesigned, or grow substantially in size (perhaps a degree of both) to become effective on higher speed roads. Now, very large cantilever signs have replaced standard signs on many new sections of motorway.

These are signs showing the effects of ‘halation’…
Halation is the effect of headlights hitting a highly reflective material used in modern signs. This causes an overglow, which can make the sign difficult to read, this is particularly challenging for older users.
Developments in directional road sign design
In the design of signs, in general, and more particularly road signs, international practise has pointed the way…
A reasonable proposition, in improving Ireland’s sign design, is to address the design of the actual type used. It has long been held by type designers that increased x-height is beneficial to typeface designs for signage. Since the 1960s, design for signage typefaces has concentrated on this and other factors of clarity – all notable new designs address x-height. In Ireland, where we’d be replacing the relatively larger uppercase words in English, use of increases x-height would be particularly applicable.
Above: A classic type, Caslon (left), has it’s x-height (height of the lowercase) compared to Transport (centre) and Clearview Hwy, the recent US road sign type. This illustrates the increased x-height of the Transport design, and how this has been surpassed by the Clearview design.
Read More...Some background on the evolution of the UK's signs
A little of the history of the UK’s road signs.
Looking at the UK’s National Archive I was struck with the fact that the situation there could have been very different, were it not for the intervention of one or two decisive individuals...
“...it has long been my belief that we would do best to submit all our proposed traffic signs to a consultant industrial artist, who is a expert on lettering. I know it can be argued that, having adopted an alphabet, all the rest is merely routine. I know too that a special relationship has been built up between the Ministry and the sign manufacturers, which introduction of a third party in the form of a consultant would complicate. Nevertheless it is remarkable what a good designer can do to the appearance of simple things, as any attentive reader to the productions of the Council of Industrial Design must know. A decision to appoint a consultant of this kind would not be popular in the Department, but outside it would, I believe, be well received.” (Allen, National Archives, 1957)
It appears, unfortunately, there was no such champion of design in Ireland, but here I’ll outline a few points around the genesis of the UK solution.
