Graded yellow

Pre-warning indication:

– Predictable driving: 
Presents a yellow triangle warning indication, shown less than 0.10 of a Second

Immediately at the beginning of the accelerator start to release to indicate deceleration intentions, human or autonomous. begins along with the green (and after) from a speed of 30mph (ca. 48 km/h) and up. 

– Improves other road users orientation by pre-ahead anticipate vehicles behavior. 

– Improves other road users perception & reaction time- With components of stopping distance and human factors as perception & reaction time, a delay of 1, 2, 3 and even up to 4 seconds is possible.In a speed of 110mph (ca. 177 km/h) we can reduce at the final stopping process between 28 to 100 meters.
This way, the tailgating cars, motorcycles and other road users will more likely be able to stop in time 

That means:
Save lives, prevent accidents or reduce their severity!

 

Yellow & Green:

 

 

Yellow:

 

 

Perception &  Reaction Time:

Autonomous vehicles continue to multiply,
They respond much faster than other road users and stop immediately.

Perception time:
How long will it take to see the hazard!?
The brain realize it is a hazard requiring an immediate reaction!?
This perception time can be as long as ¼ to ½ a second,
In cases of inattention, concentration levels go lower
Tiredness, alcohol, children in the back, mobile use are interrupting and perception time go longer.
Once the brain realizes danger – Now it’s time to react!

Reaction time:
Ending the phase of perception time now the reaction time following :
How long it takes to release from the accelerator in to the brake pedal!?

With those 2 components of stopping distance and human factors as perception & reaction time a delay of 1, 2, 3 and even up to 4 seconds is possible. In a speed of 110mph (ca. 177 km/h) we can reduce at the final stopping process between 28 to 100 meters.
This way, the tailgating vehicles will more likely be able to stop in time.
