class mosstool.trip.gmns.sta.STA(map: mosstool.type.Map, work_dir: str)

run static traffic assignment on GMNS map with persons

Initialization

_get_od(start: mosstool.type.Position, end: mosstool.type.Position)

get origin and destination of a trip

Args:

  • t: Trip, trip

Return:

  • (origin, destination): (str, str), origin and destination

_check_connection(start_road_id: int, end_road_id: int)

check if two road segments are connected

Args:

  • start_road_id: int, start road segment id

  • end_road_id: int, end road segment id

Return:

  • bool, True if two road segments are connected, False otherwise

run(persons: mosstool.type.Persons, time_interval: int = 60, reset_routes: bool = False, column_gen_num: int = 10, column_update_num: int = 10)

run static traffic assignment on GMNS map with persons. trips of persons will be sliced into time intervals. static traffic assignment will be run for each time interval. route results will be saved into persons.

EXPERIMENTAL: the method is only for trip with deterministic departure time. Other cases will be skipped.

Args:

  • persons: Persons, persons with trips

  • time_interval: int, time interval (minutes) for static traffic assignment slice. Try to set time_interval larger than trip’s travel time.

  • reset_routes: bool, reset routes of persons before running static traffic assignment

  • column_gen_num: int, number of column generation iterations for static traffic assignment

  • column_update_num: int, number of column update iterations for static traffic assignment

Return:

  • Persons, persons with route results

  • dict, statistics of static traffic assignment
