Interface LaneChangeModel

All Known Implementing Classes:

AbstractLaneChangeModel, Altruistic, Egoistic, FixedLaneChangeModel

public interface LaneChangeModel

All lane change models must implement this interface.
TODO: Lane change models should use the perceived nearby GTUs rather than a provided list of same lane traffic, etc.

Method Details

computeLaneChangeAndAcceleration

LaneMovementStep computeLaneChangeAndAcceleration(LaneBasedGtu gtu,
 Collection<Headway> sameLaneTraffic,
 Collection<Headway> rightLaneTraffic,
 Collection<Headway> leftLaneTraffic,
 Speed speedLimit,
 Acceleration preferredLaneRouteIncentive,
 Acceleration laneChangeThreshold,
 Acceleration nonPreferredLaneRouteIncentive)
                                           throws GtuException,
org.opentrafficsim.base.parameters.ParameterException,
OperationalPlanException

Compute the acceleration and lane change.

Parameters:

gtu - LaneBasedGtu; the GTU for which the acceleration and lane change is computed

sameLaneTraffic - Collection<Headway>; the set of observable GTUs in the current lane (can not be null and may include the gtu)

rightLaneTraffic - Collection<Headway>; the set of observable GTUs in the adjacent lane where GTUs should drive in the absence of other traffic (must be null if there is no such lane)

leftLaneTraffic - Collection<Headway>; the set of observable GTUs in the adjacent lane into which GTUs should merge to overtake other traffic (must be null if there is no such lane)

speedLimit - Speed; the local speed limit

preferredLaneRouteIncentive - Acceleration; route incentive to merge to the adjacent lane where GTUs should drive in the absence of other traffic

laneChangeThreshold - Acceleration; threshold that prevents lane changes that have very little benefit

nonPreferredLaneRouteIncentive - Acceleration; route incentive to merge to the adjacent lane into which GTUs should merge to overtake other traffic

Returns:

LaneMovementStep; the result of the lane change and GTU following model

Throws:

GtuException - when the speed of the GTU can not be determined

org.opentrafficsim.base.parameters.ParameterException - in case of a parameter problem.

OperationalPlanException - if DefaultAlexander perception category is not present.

getName

String getName()

Return the name of this GTU following model.

Returns:

String; just the name of the GTU following model

getLongName

String getLongName()

Return complete textual information about this instantiation of this GTU following model.

Returns:

String; the name and parameter values of the GTU following model
