Usage of emission model

[bargisou]

Is it possible to collect vehicle's emissions like collecting vehicle's data for "platoon_cacc" project? I created a text file named "000_vehicleEmissions.txt" in the results folder.But emission file dose'nt seem to update like the vehicledata.txt file.

collecting emission is per vehicle. Have you checked section '29.4 Collect Vehicle’s Emission' ?

You need to use something like this in the ini configuration for every vehicle that you need to collect emission from:

Network.V[0].record_emission = true Network.V[0].emission_list = "vehId | emissionClass | CO2 | CO | HC | NOx"

Yes.I am using it the same way for per vehicle but the text file seems to be empty even after simulation. Are there any other steps than the above mentioned to create the record list? Is it possible to measure fuel inside ventos?

Is it necessary to create an empty file named 000_vehicleEmission.txt in the results folder along with 000_vehicledata.txt file prior to simulation, for values to update in it .Or after adding above mentioned two lines in the omnetpp.ini file the file automatically generates? Is there any way to record fuel consumption also along with other data?

Same error, emission data are not logged after adding Network.V[0].record_list=" ..... " (as per documentation)". After re-installation Simulation terminated with exit code: 1, environment and path error, even though i have added the path of omnetpp.

No. That file will be created automatically No need to create it manually. Are you sure that the simulation completes without any errors? If the simulation terminates with error no output txt file will be written.

I have tested a scenario myself and it is working.

Network.V[*].record_emission = true
Network.V[*].emission_list = "vehId | emissionClass | CO2 | CO | HC | NOx"

If the problem persists, then make a video of your desktop and send it to me. You can use this software in Ubuntu to record a video from your simulation.

sudo add-apt-repository ppa:maarten-baert/simplescreenrecorder
sudo apt-get update
sudo apt-get install simplescreenrecorder

This has nothing to do with emission recording. If the simulation cannot find the SUMO path then you have not followed the installation manual correctly. Check Step 4 in section '2 Installing VENTOS' of the manual.

Thank you for your reply....The emission recording works properly....Is there any possibility to record fuel consumption also in the same way as that of emissions?

As shown in section '29.4 Collect Vehicle’s Emission' of the manual, you can add fuel into the string.

Network.V[*].record_emission = true
Network.V[*].emission_list = "vehId | emissionClass | CO2 | CO | HC | NOx | fuel"

basically adding words to the emission_list causes the simulation to collect that for you (you can remove an emission if you do not need it or you can change the order of them to change the order of column in the txt file)

Thank you once again.With the above mentioned changes I am able to collect the required data.
