Re: [sumo-user] SUMO Emission Model

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

the easiest way is to add a new emission class name in utils/emissions/HelpersHBEFA3.cpp::450

and to add the corresponding calibration parameters for all emission types in HelpersHBEFA3::myFunctionParameter

To get your own model into SUMO you need to write a class that inherits from PollutantsInterface::Helper and than include it in PollutantsInterface::myHelpers

Please consider contributing your extension (https://sumo.dlr.de/docs/FAQ.html#how_do_code_contributions_work)

regards,

Jakob

Dear all,

I am interested in estimating emissions for U.S. vehicles.  Thus, I am looking for advice on the following questions:

Is there a way to re-calibrate SUMO's emission model, for example for a U.S. Tier 3 light duty gasoline vehicle?  Specifically,  SUMO estimates emissions based on this function: 

𝑐0 +𝑐1𝑣𝑎+𝑐2𝑣𝑎2 +𝑐3𝑣+𝑐4𝑣2 +𝑐5𝑣3 

If I am able to calibrate c0 to c5 based on a U.S. Tier 3 light duty gasoline vehicle, how do I incorporate the new parameters to SUMO?

Is there a way to introduce my own emission model to SUMO?

Thank you very much!

Best regards,

Nicholas
