Road signs

Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users. The earliest road signs were milestones, giving distance or direction; for example, the Romans erected stone columns throughout their empire giving the distance to Rome. In the Middle Ages, multidirectional signs at intersections became common, giving directions to cities and towns. The first modern road signs erected on a wide bicycles in the late 1870s and early 1880s. With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to overcome language barriers, and enhance traffic safety. Such pictorial signs use symbols in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees. Pre-industrial signs were stone or wood. In the late 18th and 19th

centuries painted cast iron became popular. Since 1945 most signs have been made

from sheet aluminium with adhesive plastic coatings, these are normally

retroreflective for night-time and low-light visibility. Before the development of

reflective plastics, reflectivity was provided by glass reflectors set into the lettering

and symbols.
