ToledoPerception

Parameters:

Method Detail

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<InfrastructureLaneChangeInfoToledo> 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.

 _______
 _ _A_ _\_________
 _ _ _ _ _ _ _ _ _
 _________ _ _ ___
          \_______
     (-)        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 TimeStampedObject<SortedSet<InfrastructureLaneChangeInfoToledo>> 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.
