HBEFA3-based

Since version 0.21.0, SUMO is able to simulate vehicular pollutant emissions based on the database application HBEFA in version 3.1. Though HBEFA contains information about other pollutants, we decided to implement only the following, major ones:

- CO2
- CO
- HC
- NOx
- PMx
- fuel consumption

## Vehicle Emission Classes

The vehicle classes below map directly to vehicle classes supplied by HBEFA. This is a major difference to the clustering done with HBEFA 2.1. Note, that within HBEFA these classes are aggregates of more specific vehicle classes. To use the emission classes below prepend the class name with the HBEFA3 prefix, e.g. `emissionClass="HBEFA3/PC_G_EU4"`.

The following tables give the emissionClass strings to use in the definition of vehicle types.

### HBEFA3 heavy duty emission classes

emissionClass | description
--- | ---
Bus | average urban bus (all fuel types)
Coach | average long distance bus (all fuel types)
HDV | average heavy duty vehicle (all fuel types)
HDV_G | average gasoline driven heavy duty vehicle
HDV_D_EU0 | diesel driven heavy duty vehicle Euro norm 0
HDV_D_EU1 | diesel driven heavy duty vehicle Euro norm 1
HDV_D_EU2 | diesel driven heavy duty vehicle Euro norm 2
HDV_D_EU3 | diesel driven heavy duty vehicle Euro norm 3
HDV_D_EU4 | diesel driven heavy duty vehicle Euro norm 4
HDV_D_EU5 | diesel driven heavy duty vehicle Euro norm 5
HDV_D_EU6 | diesel driven heavy duty vehicle Euro norm 6
HDV_D_East |

### HBEFA3 passenger and light delivery emission classes

emissionClass | description
--- | ---
zero | zero emission vehicle
LDV | average light duty vehicles (all fuel types)
LDV_G_EU0 | gasoline driven light duty vehicle Euro norm 0
LDV_G_EU1 | gasoline driven light duty vehicle Euro norm 1
LDV_G_EU2 | gasoline driven light duty vehicle Euro norm 2
LDV_G_EU3 | gasoline driven light duty vehicle Euro norm 3
LDV_G_EU4 | gasoline driven light duty vehicle Euro norm 4
LDV_G_EU5 | gasoline driven light duty vehicle Euro norm 5
LDV_G_EU6 | gasoline driven light duty vehicle Euro norm 6
LDV_G_East |
LDV_D_EU0 | diesel driven light duty vehicle Euro norm 0
LDV_D_EU1 | diesel driven light duty vehicle Euro norm 1
LDV_D_EU2 | diesel driven light duty vehicle Euro norm 2
LDV_D_EU3 | diesel driven light duty vehicle Euro norm 3
LDV_D_EU4 | diesel driven light duty vehicle Euro norm 4
LDV_D_EU5 | diesel driven light duty vehicle Euro norm 5
LDV_D_EU6 | diesel driven light duty vehicle Euro norm 6
PC | average passenger car (all fuel types)
PC_Alternative | passenger car with alternative fuel technology
PC_G_EU0 | gasoline driven passenger car Euro norm 0
PC_G_EU1 | gasoline driven passenger car Euro norm 1
PC_G_EU2 | gasoline driven passenger car Euro norm 2
PC_G_EU3 | gasoline driven passenger car Euro norm 3
PC_G_EU4 | gasoline driven passenger car Euro norm 4
PC_G_EU5 | gasoline driven passenger car Euro norm 5
PC_G_EU6 | gasoline driven passenger car Euro norm 6
PC_G_East |
PC_D_EU0 | diesel driven passenger car Euro norm 0
PC_D_EU1 | diesel driven passenger car Euro norm 1
PC_D_EU2 | diesel driven passenger car Euro norm 2
PC_D_EU3 | diesel driven passenger car Euro norm 3
PC_D_EU4 | diesel driven passenger car Euro norm 4
PC_D_EU5 | diesel driven passenger car Euro norm 5
PC_D_EU6 | diesel driven passenger car Euro norm 6

Not all combinations of emissionClass and pollutant give meaningful results. The following combinations are known to be faulty as of SUMO 0.21.0: LDV + NOx, LDV_G_EU0 + NOx, LDV_G_East + NOx, LDV_G_East + PMx, PC_G_EU0 + NOx
