aequilibrae.transit.Transit

class aequilibrae.transit.Transit(project)

__init__(project)

Arguments:

project (Project, Optional): The Project to connect to. By default, uses the currently active project

Methods

__init__(project)
build_pt_preload(start, end[, inclusion_cond])	Builds a preload vector for the transit network over the specified time period
create_graph(**kwargs)
create_transit_database()	Creates the public transport database
load([period_ids])
new_gtfs_builder(agency, file_path[, day, ...])	Returns a GTFSRouteSystemBuilder object compatible with the project
save_graphs([period_ids])

build_pt_preload(start: int, end: int, inclusion_cond: str = 'start') → DataFrame

Builds a preload vector for the transit network over the specified time period

Arguments:

start (int): The start of the period for which to check pt schedules (seconds from midnight)

end (int): The end of the period for which to check pt schedules, (seconds from midnight)

inclusion_cond (str): Specifies condition with which to include/exclude pt trips from the preload.

Returns:

preloads (pd.DataFrame): A DataFrame of preload from transit vehicles that can be directly used in an assignment

>>> project = create_example(project_path, "coquimbo")

>>> project.network.build_graphs()

>>> start = int(6.5 * 60 * 60) # 6:30 am
>>> end = int(8.5 * 60 * 60)   # 8:30 am

>>> transit = Transit(project)
>>> preload = transit.build_pt_preload(start, end)

create_graph(**kwargs) → TransitGraphBuilder

create_transit_database()

Creates the public transport database

load(period_ids: List[int] | None = None)

new_gtfs_builder(agency, file_path, day='', description='') → GTFSRouteSystemBuilder

Returns a GTFSRouteSystemBuilder object compatible with the project

Arguments:

agency (str): Name for the agency this feed refers to (e.g. ‘CTA’)

file_path (str): Full path to the GTFS feed (e.g. ‘D:/project/my_gtfs_feed.zip’)

day (str, Optional): Service data contained in this field to be imported (e.g. ‘2019-10-04’)

description (str, Optional): Description for this feed (e.g. ‘CTA2019 fixed by John Doe’)

Returns:

gtfs_feed (StaticGTFS): A GTFS feed that can be added to this network

save_graphs(period_ids: List[int] | None = None)
