Many thanks!

2) TraCI is a tool to control a simulation with your custom control logic. It does not provide optimization methodology. See https://sumo.dlr.de/wiki/TraCI

Thank you so much, 
I had "sumoQueue.xml" file already and I would like to transfer it to ".csv" or excel file, so how could I do this? 
Besides, could I know the methodology of TRaCI? as I know TraCi is a tool can control traffic lights, set the phase automatically, so in TraCi we can have the new methodology to find the optimal signal timing for intersection based on real data? 
Best regards,

1) the median is Q2 and there is no Q4. see https://en.wikipedia.org/wiki/Quartile. The values are not queue lengths but statistics on the attribute passed to option --attribute (default is 'duration')
2) this is the total number of trips between the given OD pairs over the whole simulation
3) see 1)

To get queue lengths you need to use E2-detectors or --queue-output

Dear Prof. Jakob Erdmann and Users, 

There are some result files ( that I attached to this email, please look in advance first) after following your suggestion. But I have some problems when trying to extract the performances or indicators that I want.
in taz file outcome( taz_manh.xml) showed : <odInfo fromTaz="?" toTaz="?" count="202" min="15.0" minVeh="5747" max="235.0" maxVeh="2624" mean="91.38613861386139" Q1="44.0" median="81.0" Q3="130.0"/>
1. Are Q1, Q3 queueing length after 1-hour simulation? why I don't have Q2 and Q4 ?
2. count= 202 mean the total number of vehicles after 1 hour still stay in front of the stop line for all approaches?
3. could you analyze "  min="15.0" minVeh="5747" max="235.0" maxVeh="2624" mean="91.38613861386139" ?

If I am on the wrong way please show me how could I know the queueing length and the number of vehicles still stay in front of the stop line? and the total average delay for this intersection? 
Thank you.

If you only have one intersection in your network, you can use https://sumo.dlr.de/wiki/Simulation/Output#Aggregated_Traffic_Measures
If you need to distinguish multiple intersections, see https://sumo.dlr.de/wiki/Simulation/Output#values_for_junctions

Dear Users, 
I simulated an intersection based on PCU in the intersection. I followed some methodologies and found the new effective green time and cycle length for signal timing at an intersection. And I want to know what is different between the two models (before and after changing signal timing). 
How could I detect the queueing length and the number of vehicles still stay in front of the stop line?   
Which parameters can prove the new timing signal is better than existing signal control at the intersection? and how can I calculate them by SUMO?  
Thank you for your support. 

Many thanks and Best Regard !
