Re: [sumo-user] lane id - emission output
You can rebuilt the network using
netconvert -s old.net.xml --no-internal-links new.net.xml
and then run your simulation with that. However, this will give you a simplified intersection model and thus slightly different vehicle behavior.

For the output data with lane=":t2_3_1",
":t2_3" is the edge and '1' is the lane index. The name just indicates that the edge is within junction 't2' but the emissions are computed the same way as those before and after the intersection.

Jakob

Thank you Jacob.

Is it possible to print in the emission output file only the number of edge along the lane ? 
Could I change this by using the option  --no-internal-links ? 
Where I add this option ? In the configuration file ?
e.g. something like this?
    <output>
        <emission-output —no-internal-links value='emissions_tool.xml'/>
    </output>

Hello,

I notice that in the emission output file (http://sumo.dlr.de/wiki/Simulation/Output/EmissionOutput#Generated_Output) that is generated the parameter “lane” gets sometimes strange names e.g. " lane=":t2_3_1” while others are like the following “2_0”. In the latter, I suppose that the first number is the edge and the second the lane. 

Could you please specify what are the variables that the parameter "lane” can get in the emission output file? Is the above variables normal? I could expect that it would only consist of the number of edge and lane.

Thanks
Natalia
