In light of the ongoing MapRaid, certain changes to mapping guidance were needed. As time is of the essence, I have published changes to the following Wiki pages without going through the normal notice-and-comment process (though please note that these revisions underwent review by the leaders of the MapRaid in question):
https://wazeopedia.waze.com/wiki/USA/Best_map_editing_practice#Divided_and_un-divided_highways
https://wazeopedia.waze.com/wiki/USA/Junction_Style_Guide/Interchange
https://wazeopedia.waze.com/wiki/USA/At-grade_connectors
tl;dr: KISS is out, real world is in. Changes to the app have necessitated a reality-based mapping approach.
The “when to divide” language has been strengthened, following trends of the last few years but changing the decision to divide from “if problems are reported/when you get around to it” to “when you see it”. There is also now a “how to divide” section that is mostly a video for the moment.
In the case of the JSG/Interchange page, the mapping guidance itself is now more precise. This guidance nevertheless applies more generally, so a lot of duplicative, unnecessarily-siloed guidance has been removed.
Much of the at-grade connector article is new. In particular, guidance on whether to map at-grade connectors and on the geometry thereof, to my knowledge, never existed (the AGC article pointed to the JSG, and the JSG pointed to the AGC article, neither of which actually included the guidance).
