Vehicle-to-Infrastructure project gets green light

19th November 2018


New Jaguar Land Rover technology using Vehicle-to-Infrastructure (V2X) connects cars to traffic lights so drivers can avoid getting stuck at red and help free up traffic flow in cities.

The world’s first traffic lights were installed 150 years ago outside the Houses of Parliament in London. Since then drivers around the globe have spent billions of hours waiting for green. However with Jaguar Land Rover’s latest tech, their days could be numbered.

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. Like all Jaguar or Land Rover vehicles today, the F-Pace already boasts a wide range of sophisticated 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. GLOSA is being tested alongside a host of other measures to slash the time commuters spend in traffic.

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.

The advanced technology builds on the connected systems already available on the Jaguar F-Pace such as Adaptive Cruise Control.

Oriol Quintana-Morales, Jaguar Land Rover Connected Technology Research Engineer, said: “This cutting-edge technology will radically reduce the time we waste at traffic lights. It has the potential to revolutionise driving by creating safe, free-flowing cities that take the stress out of commuting. Our research is motivated by the chance to make future journeys as comfortable and stress-free as possible for all our customers.”
