Detailed Description

Helper methods for HBEFA-based emission computation.

The parameter are stored per vehicle class; 6*6 parameter are used, sorted by the pollutant (CO2, CO, HC, fuel, NOx, PMx), and the function part (c0, cav1, cav2, c1, c2, c3).

◆ addAllClassesInto()

void PollutantsInterface::Helper::addAllClassesInto ( std::vector< SUMOEmissionClass > &  list) const

◆ compute()

const PollutantsInterface::EmissionType  e,
const double  v,
const double  a,
const double  slope,
const EnergyParams *  param 
) const
inlinevirtual

Computes the emitted pollutant amount using the given speed and acceleration.

As the functions are defining emissions in g/hour, the function's result is normed by 3.6 (seconds in an hour/1000) yielding mg/s. For fuel ml/s is returned. Negative acceleration results directly in zero emission.

Parameters
[in]cemission class for the function parameters to use
[in]ethe type of emission (CO, CO2, ...)
[in]vThe vehicle's current velocity
[in]aThe vehicle's current acceleration
[in]slopeThe road's slope at vehicle's position [deg]
Returns
The amount emitted by the given emission class when moving with the given velocity and acceleration [mg/s or ml/s]
