What is Signalisation?
The term "signalisation," originally meaning "to convey information through signals," has evolved to describe the light-based systems used to manage and regulate traffic. Today, it encompasses universal signalling solutions applied across roadways, railways, seaways, and airways.
In designs where the control unit is located within the signal device or at the intersection, different timing methods are used. In fixed-time models, the traffic light operates continuously based on preset timing. In variable-time intersection control systems, other operating combinations can be applied during high-traffic periods. In detector-based applications, sensors detect real-time traffic flow and adjust the light timing accordingly. Managing signalisation systems through intersection control devices enables safe and synchronised movement of both vehicles and pedestrians.
Traffic lights are available in two-unit models (red and green) and three-unit models (red, yellow, green). Two-unit signals are often used for pedestrian crossings, and models with pedestrian icons and countdown displays are also available. Today’s signalisation systems predominantly use LED technology, which has enabled the production of dozens of different signal types through various LED forms and signal light diameters. Standard signal diameters include 100 mm, 200 mm, and 300 mm. Acoustic products and audible guiding devices designed for individuals with disabilities have helped promote inclusive urban design.

Signalisation systems are also used in railway traffic, where the needs differ. In this domain, four-colour signal lights, speed indicators, and various colour combinations are employed. This field—known as railway signalisation—involves integrated use of specialised devices, techniques, and technologies.
