Traffic signalling systems are used increasingly to improve road capacity and traffic safety. The report reviews the different systems in different countries, which are used on motorways. The basis of all systems is to stabilize the traffic flow for as long as possible. By an increase of intensity there is generally a decrease of speed. If there is a certain degree of saturation the traffic flow will become unstable, with a greater chance of accidents, and a decreasing capacity. Traffic signalling systems must give information to the driver and to do so he must have certain criteria such as good visibility, good understanding of symbols, good legibility etc. Components of traffic signalling systems are: Systems for incident detection, traffic lane signalling, alternative route indicators, warning systems for fog, wind, snow and black ice, and congestion indicators. Beside these traffic signalling systems some traffic control systems, which are more or less linked to the other systems, are discussed.
