public class LanePerceptionNone
extends AbstractLanePerception
implements org.opentrafficsim.core.gtu.perception.Perception

The perception module of a GTU based on lanes. It is responsible for perceiving (sensing) the environment of the GTU, which includes the locations of other GTUs. Perception is done at a certain time, and the perceived information might have a limited validity. In that sense, Perception is stateful. Information can be requested as often as needed, but will only be recalculated when asked explicitly. This "None" version of LanePerception does not perceive any information when perceive() is called. Rather, specific information is gathered when needed.
Perception for lane-based GTUs involves information about GTUs in front of the owner GTU on the same lane (the 'leader' GTU), parallel vehicles (important if we want to change lanes), distance to other vehicles on parallel lanes, as well in front as to the back (important if we want to change lanes), and information about obstacles, traffic lights, speed signs, and ending lanes.

Constructor Detail

LanePerceptionNone

public LanePerceptionNone(LaneBasedGTU gtu)

Create a new LanePerceptionFull module. Because the constructor is often called inside the constructor of a GTU, this constructor does not ask for the pointer to the GTU, as it is often impossible to provide at the time of construction. Use the setter of the GTU instead.

Parameters:

gtu - GTU
