class DistanceTransitionProbabilityStrategy[O, V, T] extends TransitionProbabilityStrategyBase[O, V, T]

Calculates transition probability values based on the length of the route between projected points.

Specifically, it calculates the straight-line distance between observations and the length of the shortest route connecting each pair of projected points, then calculates the difference between these values and turns it into log(probability) values with probabilityDistribution.

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

    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

    outProbabilities

    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.
