Hello Jakob,
Below is a reproducible example using TraaS.
public static void main(String[] args) {
SumoTraciConnection conn = new SumoTraciConnection(sumo-gui, config_file);
conn.addOption("step-length", "0.1"); //timestep 100 ms
try{
conn.runServer();
conn.do_timestep();
conn.do_job_set(Vehicle.add("vehicle", "vehicleType", "route", 0, 1, 1, (byte) 0));
conn.do_job_set(Vehicle.changeTarget("vehicle", "edgeToTarget"));
//This is where the error occurs
conn.do_job_set(Edge.setEffort("edgeToSetEffort", 1));
for(int counter=0; counter<5000; counter++){
conn.do_timestep();
}
conn.close();
} catch(Exception exception){
exception.printStackTrace();}
}
The simulation runs fine without ‘conn.do_job_set(Edge.setEffort("edgeToSetEffort", 1));’
Also, ‘conn.do_job_set(Vehicle.setEffort("vehicle", 0, 5000, "edge", 1))’ works fine, however, I’d like to set the effort for the edges globally.
Thanks,
Jonathan
1) this is quite strange. The last time i saw something like this it came from multiple traci threads that were trying to talk to sumo at the same time. Can you reproduce this with a single traci thread? If so, please send me a minimal scenario.
2) yes.
regards,
Jakob

Hello,
I’m currently using TraaS to interface with SUMO. I am attempting to reroute a vehicle and hope to make it change path by setting an effort to an edge (I believe this is the equivalent of setting a ‘weight’ to that edge), this effort is calculated from the congestion + other metrics.
1. When setting an edge using ‘conn.do_job_set(Edge.setEffort("edge1", 1.5))’ I receive the errors “Unexpected command and status IDs match: expected 202, got 196” given by Traci (TraaS), and “Error: Answered with error to command 0xc4: Setting effort requires a compound object.” given by the SUMO client.
Is there anything more to this? Is the syntax wrong?
2. When setting an effort for a vehicle Vehicle.setEffort(), is this simply an effort given to an edge for a period of time exclusive to this vehicle?
Many thanks,
Jonathan
