OSM Highway Access
This dataset contains estimated highway access points as recorded in Open
Street Map (OSM). It includes points where roads tagged as
intersect smaller roads (segments tagged as
We also include the more general case, in which
motorway_link segments intersect
motorway segments. The latter option is assumed to
produce a less-conservative estimate of intersections. Use the 'small roads' option
if being conservative is a priority.

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).
