Road safety signage
The faster traffic has got over the ages, the more important has it been for the erection of road safety signage to control and advise it. The earliest known road signs of any sort were put up by the Romans on their vast network of roads in order to give their armies the distance and directions to the next provincial city. Horse traffic, local horse-drawn carriages and stagecoaches were gradually introduced into Europe and the traditional finger post evolved, giving distances to towns and villages at road junctions – some dating back to the 17th Century may still be seen in parts of Britain. With the introduction of self-propelled vehicles at the end of the 19th Century came the need for more distinct road safety signage, and this has developed further up to the present day.
The overall design of all of today’s road signs is laid down by international convention, specifically the Vienna Convention on Road Signs and Signals. This convention lays down the explicit shapes, sizes and colours of all road safety signage so that an international standard between countries is maintained. Shapes and colours follow these principles:
- Triangular signs are warning signs that are used to convey to motorists a warning of impending danger and to supply information, but essentially information that advises the motorist to be careful and to be aware of some future danger.
- Circular signs depict an instruction that has to be followed. Both the mandatory and prohibition signs give instructions that have to adhered to.
- Diamond shaped yellow signs with a black border and logo are used as information signs in the United States and Canada and some parts of Europe.
- Rectangular signs are used to depict information to their road users. They are found in public information signs such as freeway direction signs, toll-rate signs, selective restriction signs (e.g. time limits for parking) and in many tourist signs.
