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).

Member Function Documentation

static SUMOReal HelpersHBEFA::compute	(	SUMOEmissionClass	c,
		const int	offset,
		double	v,
		const double	a
	)		[inline, static, private]

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. Negative acceleration results directly in zero emission.

Parameters:

[in]	c	emission class for the function parameters to use
[in]	offset	the offset in the function parameters for the correct pollutant
[in]	v	The vehicle's current velocity
[in]	a	The vehicle's current acceleration
