Models/Emissions/PHEMlight

PHEM (Passenger Car and Heavy Duty Emission Model) is an instantaneous vehicle emission model developed by the TU Graz since 1999. PHEM is based on an extensive European set of vehicle measurements and covers passenger cars, light duty vehicles and heavy duty vehicles from city buses up to 40 ton semi-trailers.

Within COLOMBO, a simplified version of PHEM, embedded into SUMO, was developed. The PHEMlight model is the result of this work. An in-depth description can be found in COLOMBO's deliverable D4.1 and D4.2.

PHEMlight uses data files that include the parameters of the modeled emission classes. While the implementation is included in standard SUMO, these input files are not available to third parties, yet.

To use PHEMlight, you have to set the path to these input files using the configuration option where  is the path.

In addition, your vehicles must be assigned to one of PHEMlight's vehicle emission classes, summarised in the following table.
