Class ChannelTaskConflict

java.lang.Object

org.opentrafficsim.road.gtu.lane.perception.mental.AbstractTask

org.opentrafficsim.road.gtu.lane.perception.mental.channel.ChannelTaskConflict

All Implemented Interfaces:

Identifiable, ChannelTask, Task

public final class ChannelTaskConflict
extends AbstractTask
implements ChannelTask

Task demand for a group of conflicts pertaining to the same conflicting road. This is defined as exp(-max(T_ego, min(T_conf))/h) where T_ego is the ego time until the first conflict, T_conf is the time until the respective conflict of a conflicting vehicle and h is the car-following task parameter that scales it.

Field Details

LOOKAHEAD

public static final ParameterTypeLength LOOKAHEAD

Look-ahead distance.

HEGO

public static final ParameterTypeDuration HEGO

Ego decay parameter.

HCONF

public static final ParameterTypeDuration HCONF

Conflicting decay parameter.

SUPPLIER

public static final Function<LanePerception,Set<ChannelTask>> SUPPLIER

Standard supplier that supplies a task per grouped set of conflicts based on common upstream nodes. This also adds a scanning task demand to each of these channels.
