Signals and Junctions
Luas trams interact with other trams, public, commercial and private vehicles on the roads, cyclists on the roads and pedestrians. The Luas Driver and signalling system control these interactions and ensure the safe movement of trams around the network.
Luas is designed to operate on a “line of sight” basis. The Luas Driver has control of the tram and is responsible for interaction with the network, road users and pedestrians. This system avoids the need for complex signalling systems such as those used on heavy rail networks. Operating on a line of sight basis is a requirement given the fact that Luas is not a fully segregated network. The line signalling system equipment includes railway and road signalling apparatus, point control and operation equipment, and selective vehicle detection equipment.
Traffic Signals and Junctions
Luas passes through the administrative areas of Dublin City Council, South Dublin County Council and Dún Laoghaire Rathdown County Council. At signal controlled road junctions the Automatic Vehicle Locator System (AVLS) interfaces with the road traffic controller to afford a level of priority to the trams.
