Models/Emissions

SUMO includes the following emission models:
 * HBEFA v2.1-based: A continuous reformulation of the HBEFA v2.1 emissions data base (open source);
 * PHEMlight, a derivation of the original PHEM emission model (closed source, commercial).

'''Table: pollutants covered by models

Pollutants emitted by the simulated vehicles can be visualised using SUMO-GUI or be written into output files, both by SUMO and SUMO-GUI. The following output can be used:
 * trip information: In combination with the emissions device, the tripinfo output contains the sum of all pollutants emitted / fuel consumed during a vehicle's journey
 * edgelane emissions: These output files contain the pollutants emitted at an edge / a lane, aggregated over a variable time span

Both models implement different vehicle emission classes. These classes can be assigned to vehicles by using the vehicle type attribute " emissionClass ". Available emission classes can be found within the emission model descriptions (HBEFA v2.1-based, PHEMlight).

=Further Interfaces= The tool traceExporter.py converts SUMO's fcd-output into files that can be directly read by the PHEM application. A tutorial on generating trace files (including PHEM input files) using this tool is available.
