Properties

Name	Type	Description
stable_edge_id	stringnull	The matching stable edge id (mapping to Replica's road network) for this segment. This id will match the Places season for Fall of the selected year.
comp_stable_edge_id	stringnull	If bidirectional is True for this segment, this field provides the matching stable edge id (mapping to Replica's road network) for the opposing direction of travel. This id will match the Places seaso
osm_id	stringnull	OSM Way ID (version 2020-07-01 for the 2019 data; version 2021-09-01 for the 2021 data; version 2022-12-01 for the 2022 data)
street_name	stringnull	The common name of the network link if available. Matches the name assigned by OpenStreetMap.
highway	stringnull	The classification of the link based on OpenStreetMap data.
length	numbernull	The distance (length) of the network link in meters.
bidirectional	booleannull	True if the provided traffic volume is the sum for both directions of an undivided roadway. False if for only one direction.
heading	integernull	The heading of the network link.
compass_direction	stringnull	The compass direction of the network link.
geometry	stringnull	The geometry (linestring) for each network link.
aadt	integernull	The annual average daily traffic volume of the network link. This value is inclusive of single-unit and combination truck volumes.
aadt_single_unit	integernull	The annual average daily traffic volume of single unit trucks on the network link. Populated for FRC 1 and 2 roads, null otherwise.
aadt_combination	integernull	The annual average daily traffic volume of combination trucks on the network link. Populated for FRC 1 and 2 roads, null otherwise.
