aequilibrae.transit.functions.breaking_links_for_stop_access

Functions

split_links_at_stops(stops, links[, tolerance])

Breaks links at the closest points for the nodes (transit stops) nearby, within a certain tolerance.

aequilibrae.transit.functions.breaking_links_for_stop_access.split_links_at_stops(stops: GeoDataFrame, links: GeoDataFrame, tolerance: float = 50) → List[GeoDataFrame]

Breaks links at the closest points for the nodes (transit stops) nearby, within a certain tolerance. New nodes are created at split points with IDs continuing from the maximum of the existing a_node and b_node values.

Parameters:

• stops – GeoDataFrame of points

• links – GeoDataFrame of linestrings. Must contain “a_node” and “b_node” columns.

• tolerance – Search radius.

Returns:

A list containing two GeoDataFrames:

• broken_links: The provided links where some have been split at stop locations. Contains updated “a_node”, “b_node”, and “geometry”. Original link attributes are preserved (duplicated for splits).

• new_nodes: Point geometries representing the new nodes created at split locations, with IDs starting from start_node_id.

Return type:

List[GeoDataFrame]
