The only thing that didn't line up was there was only one type of "Urban Collector" and there were "Rural Major Collector" & "Rural Minor Collector". "Urban Collector" & "Rural Major Collector" became "Major Collector".
In Connecticut, the most likely change at an Urban/Rural border was a "Principal Arterial - Other" changing to a "Minor Arterial". In our first version of the translation, we actually traced the route back to urban areas on both ends & if it changed back we kept it the same. The version that was proposed last year, changed the default type of "Minor Arterial", but we haven't implemented it yet because we are waiting for feedback from Ehud.
I was able to find this in the WSDOT FC guildlines PDF
While the original 1989 guidance document recommended “changing the functional classification when rural routes cross an urban boundary”, a follow-up addendum in 1991 said, “Instead of automatically upgrading the functional classification of a rural route that crosses an urban boundary, the rural classification may be continued inside the urban boundary until there is a more logical and acceptable place for a change at a point inside the urban boundary.” This 2012 guidance document reinforces the assertion of the 2008 memorandum which states that, “the practice of automatically upgrading the functional classification of a rural route that crosses an urban boundary should be phased out and eliminated. Upgrading the functional classification due to an actual change in function should be the operative criteria, rather than the location of the urban/rural boundary.”
So maybe these roads will slowly update in WSDOTS FC map. Some of the roads might have been mapped based on outdated guidelines.
