Jaguar Land Rover has developed new vehicle technology that will tell drivers when to speed up or slow down to enable them to avoid sitting at red traffic lights.
Its connected vehicle-to-infrastructure (V2I) uses a Green Light Optimal Speed Advisory (GLOSA) system, which is able to ‘talk’ to traffic lights to find out their light cycles and then feed back to individual cars what the appropriate speed is to keep traffic flow steady.
The system is intended to improve congestion and reduce emissions by preventing drivers either harshly accelerating to beat the lights or suddenly braking. With a steady stream of traffic that isn’t kept waiting at lights it is hoped it would reduce delays, commuter times and stress.
“This cutting-edge technology will radically reduce the time we waste at traffic lights. It has the potential to revolutionize 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,” said Oriol Quintana-Morales, research engineer at Jaguar Land Rover Connected Technology.
The technology is being trialled on a Jaguar F-Pace, as part of a £20m (US$25m) collaborative research initiative by the government-funded UK Autodrive project, which has helped accelerate the development of Jaguar Land Rover’s future self-driving and connected technology.
Ford recently announced a similar technology that hopes to eliminate traffic lights at intersections by using vehicle-to-vehicle communications technology. The idea is to enable cars to talk to each other on approaching junctions and adjust speed accordingly to ensure they pass each other with the need for stopping.
