Detailed Description

Helper methods for HBEFA3-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).

Member Function Documentation

◆ compute()

double HelpersHBEFA3::compute	(	const SUMOEmissionClass	c,
		const PollutantsInterface::EmissionType	e,
		const double	v,
		const double	a,
		const double	slope,
		const EnergyParams *	param ) const

inline

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 if volumetric fuel has been requested. Coasting and an engine which is off by the given param result directly in zero emission.

Parameters

[in]	c	emission class for the function parameters to use
[in]	e	the type of emission (CO, CO2, ...)
[in]	v	The vehicle's current velocity
[in]	a	The vehicle's current acceleration
[in]	slope	The road's slope at vehicle's position [deg]
[in]	param	parameter of the emission model (only used for the coasting deceleration and to determine whether the engine is off)

Returns: The amount emitted by the given emission class when moving with the given velocity and acceleration [mg/s or ml/s]

		const std::string &	vClass,
		const std::string &	fuel,
		const std::string &	eClass,
		const double	weight ) const

Returns the emission class described by the given parameters.

Parameters
