class SimpleConnectivityTransitionProbabilityStrategy[O, V, E] extends TransitionProbabilityStrategyBase[O, V, NoTransition]

A simplistic implementation to compute transition probabilities for dense probe points.

Computes a transition probability by classifying the connectivity between road segments using a topology graph. Each case is associated with a constant value for the transition probability.

This class distinguishes three cases:

  • SameVertex: The two segments are the same
  • Neighboring: The two segments are directly connected
  • Distant/Disconnected: The two segments are not directly connected

(Since version SDK 2.48) Please use DistanceTransitionProbabilityStrategy

Note

Although it produces reasonable results when the map data and the probe data are of high quality, this is not meant for implementing a general purpose map matcher.

  6. def compute(currentObservation: O, currentCandidate: MatchResult[V], nextObservation: O, nextCandidates: IndexedSeq[MatchResult[V]]): (LogProbabilitySeq, Option[IndexedSeq[Option[NoTransition]]])

    Computes the transitions from a candidate generated from the current observation to all candidates generated from the next observation.

    Computes the transitions from a candidate generated from the current observation to all candidates generated from the next observation. For each transition, the transition probability is returned. May return additional transition data, for example the path between two OnRoad candidates. This data will be part of the MatchedPath returned by a PathMatcher.

    returns

    A pair composed of

    • The transition probabilities from currentCandidate to each element of nextCandidates
    • Optionally, additional transition data from currentCandidate to each element of nextCandidates

    Storage for the calculated probabilities. After this method returns, the probabilities for each candidate from nextCandidates will be stored in the leading entries of the array.
