Computes current emission values and adds them to their sums.

The fraction of time the vehicle is on the lane is computed and used as a weight for the vehicle's current emission values which are computed using the current velocity and acceleration.

Parameters:

`[in]`	veh	The regarded vehicle
`[in]`	oldPos	Position before the move-micro-timestep.
`[in]`	newPos	Position after the move-micro-timestep.
`[in]`	newSpeed	The vehicle's current speed

Returns:: false, if the vehicle is beyond the lane, true otherwise

bool MSMeanData_Harmonoise::MSLaneMeanDataValues::notifyEnter	(	MSVehicle &	veh,
		bool	isEmit,

	)			throw () `[virtual]`

Computes current emission values and adds them to their sums.

The fraction of time the vehicle is on the lane is computed and used as a weight for the vehicle's current emission values which are computed using the current velocity and acceleration.

Parameters:

`[in]`	veh	The vehicle that enters the lane
`[in]`	isEmit	whether the vehicle was just emitted into the net
`[in]`	isLaneChange	whether the vehicle changed to the lane

virtual void MSMoveReminder::notifyLeave	(	MSVehicle &	veh,
		bool	isArrival,

	)			throw () `[inline, virtual, inherited]`

Called if the vehicle leaves the reminder's lane.

Informs if vehicle leaves reminder lane (due to lane change, removal from the network, or leaving to the next lane). The default is to do nothing.

Parameters:

`[in]`	veh	The leaving vehicle.
`[in]`	isArrival	whether the vehicle arrived at its destination
`[in]`	isLaneChange	whether the vehicle changed from the lane
