bool MSInductLoop::isStillActive	(	MSVehicle &	veh,
		SUMOReal	oldPos,

		SUMOReal	newSpeed
	)			throw () `[virtual, inherited]`

Checks whether the vehicle shall be counted and/or shall still touch this MSMoveReminder.

As soon a vehicle enters the detector, its entry time is computed and stored in myVehiclesOnDet via enterDetectorByMove. If it passes the detector, the according leaving time is computed and stored, too, using leaveDetectorByMove.

Parameters:

`[in]`	veh	Vehicle that asks this remider.
`[in]`	oldPos	Position before move.
`[in]`	newPos	Position after move with newSpeed.
`[in]`	newSpeed	Moving speed.

Returns:: True if vehicle hasn't passed the detector completely.

Removes a vehicle from the detector's map myVehiclesOnDet and adds the vehicle data to the internal myVehicleDataCont.

Parameters:

	veh	The leaving vehicle.
	leaveTimestep	Timestep (not necessary integer) of leaving.

bool MSInductLoop::notifyEnter	(	MSVehicle &	veh,
		bool	isEmit,
		bool	isLaneChange
	)			throw () `[virtual, inherited]`

Returns whether the detector may has to be concerned during the vehicle's further movement.

If the detector is in front of the vehicle, true is returned. If the vehicle's front has passed the detector, false, because the vehicle is no longer relevant for the detector.

Parameters:

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

Returns:: True if vehicle is on or in front of the detector.

void MSInductLoop::notifyLeave	(	MSVehicle &	veh,
		bool	isArrival,

	)			throw () `[virtual, inherited]`

Dismisses the vehicle if it is on the detector due to a lane change.

If the vehicle is on the detector, it will be dismissed by incrementing myDismissedVehicleNumber and removing this vehicle's entering time from myVehiclesOnDet.

Parameters:

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