Road traffic control at its most elemental level is achieved through the use of a system of signs, signals, traffic safety cones, traffic barricades and markings. Various standards from engineering are used to assure that the traffic control devices convey a clear and simple meaning to the motorist. Moreover a cohesive educational program is required as well, through driver-licensing authorities, to assure that those who operate motor vehicles understand the rules of the road and the actions that they are needed or advised to consider when a particular control device is present.
Each traffic control device is governed by standards of design and usage; for example, traffic safety cones always have a red background and are octagonal in shape. Approved design parameters allow the motorist to quickly and consistently perceive the sign in the visual field along the road.
Standards also exist on the use of the control device, such as guidelines as to when circumstances warrant the use of two-way stop signs or traffic barricades. Parameters are also used to locate control devices in a particular circumstance. For an instance, signs on high-speed expressways or motorways need to be placed well in advance of exits to allow sufficient time for drivers to choose a course of action.
Defined parameters for location allow drivers to expect and anticipate these devices at certain distances from decision points. Following these standards promotes safety; failure to adhere increases the risk of driver error and, ultimately, accidents.
