Jaguar Land Rover has unveiled its Green Light Optimal Speed Advisory (GLOSA) system allowing cars to ‘talk’ to traffic lights and informing the driver the optimum speed 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 GBP20m (US$26m) collaborative research project. . JLR says connected technology trials increase the line of sight of a vehicle when it is linked via the internet to other cars and infrastructure. GLOSA is being tested alongside other measures to reduce 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 they should proceed at a junction.
JLR 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 technology builds on the connected systems already available on the Jaguar F-Pace such as Adaptive Cruise Control.
“This technology will radically reduce the time we waste at traffic lights,” said JLR connected technology research engineer, Oriol Quintana-Morales.
“It has the potential to revolutionise driving by creating safe, free-flowing cities that take the stress out of commuting.”
The trials are part of the GBP20m government-funded project, UK Autodrive, which has helped accelerate the development of Jaguar Land Rover’s future self-driving and connected technology, as well as strengthening the Midlands’ position as a hub of mobility innovation.
