- An exit number is a number assigned to a road junction, as an exit from a freeway. It is usually marked on the same sign as the destinations of the exit.
ref=*
is used when the exit has a specific number assigned to it.noref=yes
is used when the exit doesnt have any official number assigned to it.

Use the Tasking manager link in the mapping ticket.
When we lock a motorway in Tasking manager, a link appears to take us directly to the road in Checkautopista2
These are the colour representations for the exits detected in Checkautopista2
- Browse along the route and check the ways on both directions at every Exit location for the following:
- There is a
motorway_junction
in the starting node of themotorway_link
exiting the highway red dot - The
motorway_junction
has a correct exit numberref
value as per the source. Nodes with missingref
tags represented by a blue dot - The exit number on both directions are the same.
- There is only one exit in a direction for every exit number.
Add missing exit numbers
-
Download the data and mapillary layer to locate a signboard around the blue marker in the imagery.
-
Use a combination of Mapillary, Exitexplorer, Exitlist info to add the
ref=*
tag onhighway=motorway_junction
(stick to using Mapillary as primary source and move to others in case of unavailablity of information) -
If it is confirmed there is no exit number for the
motorway_junction
add another tagnoref=yes
to indicate the exit does not have an official reference number.
Look out of highway sign boards in the satellite imagery. They may look something like this-
Places to look for-
-
It is not necessary that exit numbers are sequential. It might be 45 after 41.
-
There are some
motorway_junction
which don't have any associated exit number. Addnoref=yes
on these nodes. -
If there are multiple exits on the same signboard then you can tag them as
ref=* ; *
instead ofref:left=*
andref:right=*
until you are confirmed with that. -
Ignore the
highway=motorway_junction
where the traffic flow is towards the motorway
destination
- placename that the way exiting from the freeway leads to.destination:ref
- reference of the roads directly ahead.destination:street
- streetname the way exiting from the freeway leads to.
- Look out for red outer circle in Checkautopista for missing destination. Use
Open in JOSM
button to open the node in JOSM. Orange outer circle representsexit_to
tag and we don't need to add destination tags in the way. Green outer circle represent that the concern way already has destination tag.
-
Download the data around the
motorway_junction
and mapillary layer to locate a signboard. -
Use combination Mapillary images and Exit explorer to add destination as
destination=*
onmotorway_link
ways and the destination highway asdestination:ref=*
.
- Use
;
to separate multiple destination and refs. - Read more on Highway intesection to understand them better.
