SimpleMatcher

class leuvenmapmatching.matcher.simple.SimpleMatcher(*args, **kwargs)

A simple matcher that prefers paths where each matched location is as close as possible to the observed position.

Parameters:

• avoid_goingback – Change the transition probability to be lower for the direction the path is coming from.
• kwargs – Arguments passed to BaseMatcher.

logprob_obs(dist, prev_m, new_edge_m, new_edge_o, is_ne=False)

Emission probability.

Note: In contrast with a regular HMM, this is not a probability density function, it needs

to be a proper probability (thus values between 0.0 and 1.0).

logprob_trans(prev_m: leuvenmapmatching.matcher.base.BaseMatching, edge_m: leuvenmapmatching.util.segment.Segment, edge_o: leuvenmapmatching.util.segment.Segment, is_prev_ne=False, is_next_ne=False)

Transition probability.

Note: In contrast with a regular HMM, this is not a probability density function, it needs

to be a proper probability (thus values between 0.0 and 1.0).
