Jaguar Land Rover is trialling new technology which is intended to help drivers avoid getting stuck at red lights, improving congestion and reducing emissions.

The Green Light Optimal Speed Advisory (GLOSA) technology tells the driver the required speed to avoid getting stuck at traffic lights and works using vehicle-to-infrastructure tech that connects cars to traffic lights.

It is currently being trialled on an F-Pace, as part of a larger autonomous and connected driving project, Autodrive, that Jaguar Land Rover is a part of alongside other car makers such as Ford.  

JLR told Autocar that the technology should be on production cars within the next three to five years. A spokesman said: “From a technical point of view, we’re ready but the infrastructure required is not.”

He added that the West Midlands is likely to see this technology in the near future as it is home to one of the major connected and autonomous testbeds in the UK (along with Milton Keynes) as well as various 5G trials, which are vital for this technology to work.

JLR is not the first to publicise that it is using this technology. Ford, as part of the same Autodrive project, announced it was trialling GLOSA on a Mondeo hybrid in 2016. Meanwhile, Volvo has previously announced it is also developing the technology, but there has been no word of trials on public roads.

The traffic light detection system is intended, said JLR, to slash the time commuters spend in traffic. It is one of a number of technologies currently being tested by the car maker to achieve this goal. For example, Intersection Collision Warning alerts drivers when it is unsafe to move forward at junctions.

Oriol Quintana-Morales, JLR connected technology 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.”

Jaguar F-Pace 2.0d R-Sport 2016 road test review

Jaguar takes a typically sporting approach with the F-Pace, but it isn't quite enough to better its sibling, the Land Rover Discovery Sport

The service departments can't keep up 'now'.

HaHa !

Now all the side roads will be clogged up with JLR customers who have been re-routed along unsuitable rat-runs to avoid the red lights....and since none of them would ever give way...there they will stay -smashing each others door mirrors off because their cars are too wide!!!

Good news for the rest of us though.

About 50 years ago, there was a stretch of the A4 through Slough Trading Estate where, if you drove through the first set of lights at 30 mph, you would have green for the next half a dozen lights. I don't think it still operates that way, or else there's too much traffic for it to work. I always thought it a good idea.

to find sequenced traffic lights. They used to be in many towns, and are you say, if you approached the 1st set at the right speed and held a certain speed, then they all turned green for you. 

It was then realised that this pattern was too helpful to motorists, and so most cities changed them, deliberately, in order to create congestion, to make cities less "car-friendly".

I therefore question how this technology is going to work. Is it really going to allow you to change the lights, or the duration of the lights at junctions, so that they clear the traffic ahead, before changing "your" lights to green, allowing the blockage ahead to move, which is always the current problem, where you sit watching the lights sequence from red to green and back again several times, but you are unable to move because the sequencing allows traffic to enter and block the junction/roundabout from other directions. If it is just about speed, that is meaningless, as they lights are never sequenced or never sequenced sensibly now to clear traffic.

Maybe car manufacturers could concentrate on making the existing technology that they already fit to their cars work properly. JLR especially. How about the "battery low, start engine warning", after you have driven 100 miles and only remained in the car for 5 minutes; or Hyundai where it warns you about battery discharge and automatically shuts down and turns off the radio after 10 minutes or less, even if you turn off the screen to save the battery. 20 years ago, you could listen to the radio for 2 hours or more with the engine switched off, with no problem.

The class leading, premium, ego enhancing Range Rover Sport is already equipped with a function for avoiding red lights. JLR call it an accelerator pedal...

Maybe they can also make it impossible to park on zig zag zones outside schools in your Disco/Rangie when dropping off your single child 300 metres from your home?  (Though that would just increase sales of Q7's.......).  I know it's a cliche, but I challenge you to go to a primary school at 3.20pm and check......

Probably best to not go hanging around outside primary schools at leaving time.. I don't think "I'm looking to see how many Range Rover drivers park on the zig zag lines officer" would cut it.

Will this technology still work on the back of a tow truck?

Or just ride a bicycle....

 I thought that if you were travelling at the speed limit for the Junction, Crossroad or whatever light controlled Road that didn’t ,if the Road was clear, the delay was shorter?, whereas if you raced up to the line, and because of this the sequence was longer?, it’s impatience for whatever reason that cause accidents at lights, I do wish Drivers would realise this, if your late, your late because you didn’t leave or create sufficient time to allow for unseen problems.
