Jaguar Land Rover has developed new technology using Vehicle-to-Infrastructure (V2X) that connects cars to traffic lights so drivers can avoid getting stuck at red and help free up traffic flow in cities. The Green Light Optimal Speed Advisory (GLOSA) system allows cars to “talk” to traffic lights and inform the driver the speed they should drive as they approach junctions or signals.
Widespread adoption of the V2X technology will prevent drivers from racing to beat the lights and improve air quality by reducing harsh acceleration or braking near lights. The goal is for the V2X revolution to create free-flowing cities with fewer delays and less commuter stress.
The connected technology is currently being trialled on a Jaguar F-PACE, as part of a £20 million collaborative research project. The F-PACE already uses a range of Advanced Driver Assistance (ADAS) features. The connected technology trials are enhancing existing ADAS features by increasing the line of sight of a vehicle when it is connected via the internet to other vehicles and infrastructure.
For example, Intersection Collision Warning (ICW) alerts drivers when it is unsafe to proceed at a junction. ICW informs drivers if other cars are approaching from another road and can suggest the order in which cars should proceed at a junction.
Jaguar Land Rover has also addressed time lost to searching for a parking space by providing real-time information of available spaces to drivers and developed an Emergency Vehicle Warning to alert motorists when a fire engine, police car or ambulance is approaching.
