As far as I know traci.simulationStep calls simulationStep on your first connection created via traci.start, you need to also call conn2.simulationStep. Instead of calling traci.simulationStep you can get the its connection of the first client via traci.getConnection, see e.g. traci.start(sumoCmd, port=8813, label="sim1") conn1 = traci.getConnection("sim1") conn1.setOrder(1) The following snippets should work: --------------- Client 1: --------------- sumoBinary = "C:\\Projekte\\Sumo_Eclipse\\Releases\\sumo-win64-1.1.0\\sumo-1.1.0\\bin\\sumo-gui" sumoCmd = [sumoBinary, "-c", cfg] traci.start(sumoCmd, port=8813, label="sim1") conn1 = traci.getConnection("sim1") conn1.setOrder(1) step = 0 while step < 1000: conn1.simulationStep() step += 1 conn1.close() --------------- Client 2: --------------- traci.init(port=8813, label="sim2") conn2 = traci.getConnection("sim2") conn2.setOrder(2) step = 0 while step < 1000: conn2.simulationStep() step += 1 conn2.close() Von: sumo-user-bounces@xxxxxxxxxxx [mailto:sumo-user-bounces@xxxxxxxxxxx] Im Auftrag von ratzenmeier@xxxxxx

Betreff: Re: [sumo-user] two clients, one SUMO connection (python - TraCI) okey, still not working, here are my to client-snippets: # default port PORT = 8813 client2 = Com() class runner: port = getFreeSocketPort() # if getFreeSocketPort returns None, initialize with default value if not port: port = PORT sumoBinary = "sumo-gui.exe" # starting sumo traci.start(cmd=[sumoBinary, "-c", "pathToConfig\\SUMO\\config.sumo.cfg", "--num-clients", "2"], port=8813) # establishing client order traci.setOrder(1) # default port PORT = 8813 class Com: def traci_client2(self): port = getFreeSocketPort() # if getFreeSocketPort returns None, initialize with default value if not port: port = PORT traci.init(port=8813, label="sim2") conn2 = traci.getConnection("sim2") conn2.setOrder(2) while traci.simulation.getMinExpectedNumber() > 0: traci.simulationStep() so, as far as i understand, it stucks while it loads because sumo is waiting for client2? Maybe you can see anything in my code. Gesendet: Donnerstag, 20. Dezember 2018 um 15:13 Uhr

Betreff: Re: [sumo-user] two clients, one SUMO connection (python - TraCI) 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() Von: sumo-user-bounces@xxxxxxxxxxx [mailto:sumo-user-bounces@xxxxxxxxxxx] Im Auftrag von ratzenmeier@xxxxxx

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. Gesendet: Donnerstag, 20. Dezember 2018 um 11:31 Uhr

Betreff: Re: [sumo-user] two clients, one SUMO connection (python - TraCI) 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. _______________________________________________
