In September 2010, UNECE published the report “Consolidated Resolution on Road Signs and Signals”. The concept of ‘self-explanatory’ roads encompasses many different elements of the design, layout and operation of the road network. However, this term serves well to illustrate the need to create an environment that can be easily understood and safely operated by all its users. The Road Safety Forum has been mandated by the United Nations General Assembly to review this fundamental area and to make provisions for road signs and signals that are in line with the requirements of ever growing motorization.
