public class ToledoPerception extends AbstractPerceptionCategory<LaneBasedGtu,LanePerception> implements LaneBasedPerceptionCategory
Wrapper class around InfrastructureCategory that forwards all methods except for infrastructure lane change info. These methods determine and return infrastructure information of type InfrastructureLaneChangeInfoToledo, which includes split number.

    • updateInfrastructureLaneChangeInfo

      public void updateInfrastructureLaneChangeInfo(RelativeLane lane) throws GtuException
      Updates the infrastructural lane change info.
      Parameters:
      lane - RelativeLane; relative lateral lane
      Throws:
      GtuException - when GTU is not initialized

    • getInfrastructureLaneChangeInfo

      public final SortedSet<LaneChangeInfo> getInfrastructureLaneChangeInfo(RelativeLane lane)
      Returns infrastructure lane change info of a lane. A set is returned as multiple points may force lane changes. Which point is considered most critical is a matter of driver interpretation and may change over time. This is shown below. Suppose vehicle A needs to take the off-ramp, and that behavior is that the minimum distance per required lane change determines how critical it is. First, 400m before the lane-drop, the off-ramp is critical. 300m downstream, the lane-drop is critical. Info is sorted by distance, closest first.

          \_______
     (-)        Lane-drop: 1 lane change  in 400m (400m per lane change)
     (--------) Off-ramp:  3 lane changes in 900m (300m per lane change, critical)
     
     (-)        Lane-drop: 1 lane change  in 100m (100m per lane change, critical)
     (--------) Off-ramp:  3 lane changes in 600m (200m per lane change)
      Parameters:
      lane - RelativeLane; relative lateral lane
      Returns:
      infrastructure lane change info of a lane

    • getTimeStampedInfrastructureLaneChangeInfo

      public final org.opentrafficsim.base.TimeStampedObject<SortedSet<LaneChangeInfo>> getTimeStampedInfrastructureLaneChangeInfo(RelativeLane lane)
      Returns time stamped infrastructure lane change info of a lane. A set is returned as multiple points may force lane changes. Which point is considered most critical is a matter of driver interpretation and may change over time. This is shown below. Suppose vehicle A needs to take the off-ramp, and that behavior is that the minimum distance per required lane change determines how critical it is. First, 400m before the lane-drop, the off-ramp is critical. 300m downstream, the lane-drop is critical. Info is sorted by distance, closest first.

      Returns the prospect for speed limits on a lane (dynamic speed limits may vary between lanes).
      Parameters:
      lane - RelativeLane; relative lateral lane
      Returns:
      prospect for speed limits on a lane

    • getLegalLaneChangePossibility

      public final org.djunits.value.vdouble.scalar.Length getLegalLaneChangePossibility(RelativeLane fromLane, LateralDirectionality lat)
      Returns the distance over which a lane change remains legally possible.
      Parameters:

      Throws:
      NullPointerException - if lat == null

    • getPhysicalLaneChangePossibility

      public final org.djunits.value.vdouble.scalar.Length getPhysicalLaneChangePossibility(RelativeLane fromLane, LateralDirectionality lat)
