Method Details

estimate

public NeighborTriplet estimate(LaneBasedGTU perceivingGtu, LaneBasedGTU perceivedGtu, Length distance, boolean downstream, Time when) throws ParameterException

Estimate headway, speed and acceleration.

Specified by:

estimate in interface Estimation

Parameters:

perceivingGtu - LaneBasedGTU; perceiving GTU

perceivedGtu - LaneBasedGTU; perceived GTU

distance - Length; actual headway at 'now' (i.e. not at 'when' if there is a reaction time)

downstream - boolean; downstream (or upstream) neighbor

when - Time; moment of perception, reaction time included

Returns:

NeighborTriplet; perceived headway, speed and acceleration

Throws:

ParameterException - on invalid parameter value or if parameter is not available
