OSM Highway Access

Overview

This dataset contains estimated highway access points as recorded in Open Street Map (OSM). It includes points where roads tagged as highway=motorway_link intersect smaller roads (segments tagged as highway=trunk or highway=primary or, optionally, segments tagged as highway=motorway).

OpenStreetMap® is open data, licensed under the Open Data Commons Open Database License (ODbL) by the OpenStreetMap Foundation (OSMF). Users are free to copy, distribute, transmit and adapt OSM data, as long as they credit OpenStreetMap and its contributors. If users alter or build upon OSM data, they may distribute the result only under the same licence. For more details, see https://www.openstreetmap.org/copyright

Attributes

intersecting_road_name

Name of road from which highway is accessed

string
highway_name

Name of highway accessed at this point

string
intersecting_road_tags

JSON string for all OSM tags on intersecting road segment

string
highway_tags

JSON string for all OSM tags on motorway link

string
includes_motorway_intersections

Indicates whether the highway access point includes road segments tagged as 'motorway'. Including these motorway segments in the query used to compute intersections results in an increase in the number of false positives and, thus, the risk over-counting (i.e. 'highway access points' that don't really exist).
