Packages that use HeadwayGTU

Package	Description
org.opentrafficsim.road.gtu.following	GTU (Car) following models such as IDM+.

Uses of HeadwayGTU in org.opentrafficsim.road.gtu.following

Method parameters in org.opentrafficsim.road.gtu.following with type arguments of type HeadwayGTU

Modifier and Type	Method and Description
DualAccelerationStep	GTUFollowingModel.computeAcceleration(LaneBasedGTU referenceGTU, Collection<HeadwayGTU> otherGTUs, org.djunits.value.vdouble.scalar.Speed speedLimit) Compute the lowest accelerations (or most severe decelerations) that would be used if a referenceGTU is present (inserted, or not removed) in a set of other GTUs. If any GTU in the set of otherGTUs has a null headway (indicating that the other GTU is in fact parallel to the referenceGTU), prohibitive decelerations shall be returned. Two AccelerationStep values are returned in a DualAccelerationStep. TODO We should probably add a be ready to stop before argument to prevent vehicles that cannot see their leader, or should slow down for a crossing from accelerating to unsafe speeds.
DualAccelerationStep	AbstractGTUFollowingModel.computeAcceleration(LaneBasedGTU referenceGTU, Collection<HeadwayGTU> otherGTUs, org.djunits.value.vdouble.scalar.Speed speedLimit) Compute the lowest accelerations (or most severe decelerations) that would be used if a referenceGTU is present (inserted, or not removed) in a set of other GTUs.
