Re: [sumo-user] Sumo Random
see https://sumo.dlr.de/docs/Simulation/Randomness.html#departure_times

The option --random initializes the random seed (option --seed) with a random value drawn in a non-repeatable manner from the operating system.
The upside is that you don't need to set option --seed with a specific seed. The downside is, that you cannot easily reproduce such a simulation since you don't know the seed.

Good afternoon,

Thank you very much!

Great, it worked with random-depart-offset. I set a value of 10 seconds. Is there a recommended value?

Just the random parameter, what does it do? I'm including it as well.

Sds,

Good evening,

In a simulation aimed at generating randomness, I placed the following script in the sumo.cfg file:

<processing>
<random value="true"/>
</processing>

However, after reloading several times and observing the start of the simulation, I always see the same vehicles being initialized.

I would like to know what the procedure would be so that the model is initialized in a variable way: the time of vehicle insertion, variation in the insertion of the vehicle type, etc.

The flow was generated using Routesampler.

Thank you very much!

Sds,

Pedro Oliveira
