Hello Mirko,

Thanks for the explanation.
We typically run at 1KHz and I think SUMO at 100Hz so that would explain it.
We will need to add a simple filter at our end.

Matthew.

Hi Matthew,

 

AFAIK brake light visualisation is pretty basic. Every time step it is decided whether to draw it or not. Now if you use very short time steps, you may encounter the mentioned pattern because in some situations SUMO vehicles do not come to a complete stop but travel at very low speeds (somehting like 0.01m/s).

 

Best regards

Mirko

Sorry if this has been asked before. It is very hard to google because of real car models like Tata Sumo!
 
In large traffic queues we see brake lights flickering much faster than real life.

I have found
and
but these do not say how to configure the brake deceleration threshold.

Is this possible?
 
Thank you,
