Re: [sumo-user] How to output a xml file from a Traffic Light?

Traffic lights only support output regarding to their switching operations https://sumo.dlr.de/docs/Simulation/Output/Traffic_Lights.html

However, you can couple an e2detector so it's output intervals are synchronized with an traffic light cycle: https://sumo.dlr.de/docs/Simulation/Output/Traffic_Lights.html#coupled_lane_area_detectors

Also, you can generate e2 / e3 detectors to cover the approaches to a traffic light: https://sumo.dlr.de/docs/Simulation/Output/index.html#values_for_junctions

I’m sorry, I’m not sure what you meant by NEMA type Controller, what I was the output of a xml file similar to the e2 detectors like this one

 

But for traffic lights in xml format.

 

Thank You in Advance.

If you are using NEMA type of controller, you should be able to output the signal light state history by setting whetherOutputState parameter to “true”. If you need the record to be at every 0.1 sec frequency, just set the simulation resolution to be 0.1 sec by using the --step-length <TIME> option.

 

Thanks,

Dear Users,

 

I’d like to know how to create an output a traffic light’s data to a xml file similar to e2 detectors like this one

With the freq of 10

 

 

Thank you very much in advance, and God Bless
