Jaguar Land Rover has announced it will implement Green Light Optimal Speed Advisory (GLOSA) technology on a trial basis. The system utilizes vehicle-to-infrastructure (V2X) connectivity, allowing cars to “talk” to traffic lights while informing drivers of the speed they should travel to avoid having to stop.
GLOSA isn’t a new concept. In fact, it’s been kicked around for years as a potential way to minimize congestion and improve urban traffic flow. The theory involves creating a network of traffic signals that perpetually communicate with connected automobiles and encourage the vehicles to self-regulate their speed. The system works with timed signals, though implementing adaptive signals is believed to further improve the system’s overall benefits.
It’s not the most revolutionary technology under consideration right now — it still relies on the city’s infrastructure keeping tabs on your vehicle to function properly (something we have moderate concerns about). But, if the industry does pivot this way, GLOSA is one of the most common-sense and least invasive automotive advancements currently on the drawing board.
First of all, it doesn’t force the car to do anything (not yet, anyway). The stop light will continue doing its job while providing the driver with some useful information, via V2X, that they’re welcome to ignore. If you want to slam on the brakes at the last minute, you still can. The goal isn’t to eliminate driver involvement; rather, developers just want to make hectic commutes a little more bearable.
“This cutting-edge technology will radically reduce the time we waste at traffic lights,” explained Oriol Quintana-Morales, JLR’s Connected Technology Research Engineer. “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.”
GLOSA is being tested alongside several other advanced driver assistance systems, all aimed at improving commutes and reducing emissions. JLR uses the Jaguar F-Pace as its test platform for the tech as part of a $26 million research project based in the United Kingdom.
