This paper reviews some of the key questions relating to the development of variable roadside driver information, optical displays and related standards over recent years. A brief description is given of the progress made in drafting European standards in this area and the present position is outlined. The background is described to the development of an innovative optical design which is much less susceptible to the effects of sun phantom and washout is described.
