Description and goal

Editoast part of : https://github.com/osrd-project/osrd-confidential/issues/1267
Link with :

Determining the occupation of a level crossing:

• Retrieve the list of requested trains
• Retrieve the requested level crossings
• For each train / valid occurrence:
  • Retrieve its path and its simulation
  • For each level crossing:
    • Retrieve the intersection point with the level crossing (optional)
    • If yes, create a new occupation block:
      • Determine the train’s direction relative to the level crossing (watch out for reversed)
      • Deduce which pedal must be taken into account
      • Find the arrival time on the pedal through interpolation (arrival at the point intersection - pedal_distance)
      • Find the occupation duration through interpolation (arrival at the point intersection + short_zone_length + train_length)

START_TO_STOP : UPSTREAM
STOP_TO_START : DOWNSTREAM

Acceptance criteria

• Editoast returns the occupation of given level_crossings for given trains
