Module probability 

Probability calculation module

Implements exponential decay probability formulas for distance and heading, and transition probability for HMM-based map matching.

Functions

calculate_combined_probability

Calculate combined probability from distance and heading components.

calculate_distance_probability

Calculate probability based on distance using exponential decay.

calculate_heading_probability

Calculate probability based on heading difference using exponential decay.

calculate_transition_probability

Calculate transition probability between two map-matched candidates using the Newson & Krumm (2009) formula.

is_near_netelement_edge

Check whether a candidate’s projected point is near a netelement endpoint.
