You might also fish the phone out of your backpack and plug it in to charge if it’s running low on charge. Audi suggests it’s enough time to remove your jacket if you’re warm, or turn to the back seat to check on the well-being of your baby. Knowing how long you have until green - almost two minutes at a long red in Las Vegas (the above shows 109 seconds) - means you could do something useful. Stress can be high, including at traffic lights.
#AUDI WARNING LIGHT UP AND DOWN ARROWS LIGHT ICON DRIVERS#
The incidence of no-current-information blackouts should decrease, Ova says, as TTS massages more and more data.Īudi instrumented volunteer drivers to determine stress levels.
That was because there wasn’t enough solid current and past data on the light to confidently project a time to green, according to Kiel Ova, chief marketing officer of Traffic Technology Services, Audi’s partner on Traffic Light Information. There were a few instances when the display showed a red light ahead, then the display showed nothing even though the light was still red and the car was not yet at the light. In a handful of cases there was a red light that wasn’t managed, and thus no information on that signal. The driver decides when to start up by looking at the physical traffic light. On a test drive around Las Vegas, I found the countdown was accurate in most cases to within a second.
It’s not by the windshield lane keep assist / forward collision warning camera signalling when the light turns green, and it’s not by DSRC radio in the 5.9 GHz band. If it’s on, the car assumes you’re turning left.Īll this is done via the Audi Connect cellular connection and V2I. If you pull into the left-turn lane whose green signal precedes by 10 seconds the through-traffic green, TLI adjusts the time-to-green countdown not by super-accurate GPS positioning, but by the simple expedient of checking for the left-turn signal.
