Jaguar tests V2X traffic light system

Jaguar is trialling vehicle-to-infrastructure (V2X) technology on its models, with the systems able to reduce congestion and improve traffic flow by advising drivers of the optimum speed so as not to get stuck at traffic lights.

Jaguar's Green Light Optimal Speed Advisory (GLOSA) system is just one element of potential connected car applications, with the potential for cars to ‘talk’ to traffic lights meaning that fuel use can be reduced, as drivers spend less time waiting or using engine stop/start systems.

By not accelerating as hard, or braking and wasting momentum already built up, fuel usage savings could be significant when widely adopted, particularly in urban areas.

Audi is already trialling a similar set-up in the United States, but this is the first time a trial such as this has taken place in the UK. Currently being trialled on a Jaguar F-Pace, the project is part of a £20 million UK Autodrive collaborative research project.

Jaguar GLOSA

GLOSA is being tested alongside other systems such as Intersection Collision Warning (ICW), which alerts drivers as to when it is unsafe to proceed at a junction. The system lets drivers know if other cars are approaching from another road, and it can also suggest the order in which cars should proceed at a junction.

Real-time parking space information streamed to the car is also being tested, along with the previously reported Emergency Vehicle Warning system, which tells drivers when emergency services are approaching to make moving aside safer.

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."
