[sumo-user] remove randomness in simulation

[Kaveh Khoshkhah <khoshkhah@xxxxxxxxx>]

Hi,

I ran two simulations and expected the result to be the same.

1) sumo -n net.xml -r routes_0.xml --random false --end 3600

2) sumo -n net.xml -r routes_0.xml,routes_1.xml --random false --end 3600

But I got different results. Depart time of all vehicles in routes_0.xml is less than 3600, and Depart time of all vehicles in routes_1.xml is more than 3600. But the simulation results are different.

Is there any solution for avoiding the randomness in simulations?

I thought maybe the randomness is from TLS. So I added  "--tls.all-off true " to the simulation command. But the results are different again.

The routes format for all vehicles look like this:

<vehicle id="0_10" depart="100" departLane="free" departSpeed="max">

<route edges="edge1 edge2 edge3 edge4"/>

</vehicle>

The sumo version is 1.13.0, which I Installed by pip.

Best regards,

Kaveh
