I agree that it should. I would propose the following:
Small Detour Prevention Mechanism
Waze routing includes a mechanism to prevent routing off a highway/freeway only to be routed right back on the same highway/freeway. The assumption is that drivers will prefer to remain on the highway/freeway even if waze calculates that taking a series of ramps or other collector/distributor roads is slightly faster or shorter.
Waze routing will not present routes over a detour off a highway/freeway and back on that same highway/freeway when each of the following conditions are met:
1) the last segment on the highway/freeway before the detour has the same street name and same city name as the next highway/freeway segment after the detour,
2) the detour is more than one segment long,
3) the detour is over segments of a different road type than the highway/freeway, and
4) the detour is under the threshold length as defined below.
The threshold length if the highway/freeway is a freeway or a major highway is 5 kilometers. The threshold length if the highway is a minor highway is 500 meters.
The issue I have with the other quote is that it does not mention city names, which we know must be the same as well. To waze insiders this may go without saying, but in the wiki I think it needs to be said.
Where should it be added? There is the discussion on collector distributor mapping here: https://www.waze.com/wiki/Limited_Acces ... utor_Lanes
Although the detour prevention mechanism discussion may unduly complicate that section.
There is also the technical information section here: https://www.waze.com/wiki/Technical_Information
But I'm not sure if that is really meant for community editing or not.
