When the sumo gui has been started, it is waiting for the second client to 
connect. Note that you have to call setOrder for all clients and to call 
simulationStep for each client to proceed with the simulation
 
e.g. for the second client:
 
traci.init(port=xxxx, label="sim2")
conn2 = traci.getConnection("sim2")
conn2.setOrder(2)
 
step = 0
while step < 1000:
    conn2.simulationStep()
    step += 1
 
conn2.close()

Betreff: Re: [sumo-user] two clients, one SUMO connection (python - TraCI)
 
thanks for the information Jakob!
 
So I implemented it, but when I start my runner script, it opens my sumo-gui as 
usually, but it's only displaying "starting server on port xxxx" and nothing 
happens, just loading. When I'm changing the --num-clients in the traci.start 
to "1" it starts normally.
 
Any ideas?
 
Greetings

Hello everyone,
 
so i'm new to SUMO and want to connect two different clients (both python 
scripts, Interface: TraCI) to the same SUMO connection. 
How can I do that exactly? I read about the simulationSteps from the post 
yesterday, but I can't manage to implement it.
 
Thanks a lot.
 
Greetings!
