Sorry, but in this case the state's DOT wins.

I'd be uncertain about accepting poor routing as the result of a strict adherence to FC (or any other methodology, including the one used in the Southeast) as "winning."

Yes it does. It's here and it's been in the Wiki for a while. However that site does not appear to work from IP addresses that GeoIP from out of state. Last time it worked for me was when I was there last December. F.I.T. may also have GIS resources usable with ArcGIS.

It doesn't work in-state, either, so effectively there is not a Florida FC reference we could use. (EDIT: Site page is responding sporadically, now.) I wrote the DOT yesterday requesting a URL for Florida’s FC system. The read receipt came back today. Standing by for a response and will advise all if I get one.

Because road type is the fall-back for long distance routing.

I'm in a relatively rural area where long-distance routing over primary streets, minor highways and major highways is the norm.

Regardless, the consensus appears we’re going ahead with FC and debate is over. I've had opportunity to make my points.

[EDIT: Response received from FL DOT for functional classification:

Must have been written by a U. of Florida or FL State undergrad. It's awful.]

1. I remain in the minority on FC, not because I wouldn't like to see a national standard, but assuming Waze says OK to FC, this thread shows we continue to struggle with exceptions. Where there are exceptions, we will continue to have back & forth conflicts between editors.

Out-of-area editor: "It's a primary street according to FC."
Local editor: "No, it's a minor highway. I know, because I drive it frequently."

Local editors will constantly have to go back and 'fix' what an outside-the-area editor changed. Reading the previous posts, there's other subjective areas, too.

2. So while I am looking for ways to support FC (it sounds like I'll have to), FC seems to be a baseline at best, with each state having it's own exception list. It is not the holy grail of routing (see point 4, below), nor is the simple method I encourage Southeast editors to use, which is US = major, State Hwy/Rte/Rd (or SR) = minor highway, and Co Rte/Rd (or CR) = primary. It's just simpler and eliminates the local vs. out-of-area editor disagreements.

3. Florida doesn't even have a web-based FC map. Referring to earlier posts that some states do not have county roads, agreed there can't be a carte blanche rule that county roads are Primary Streets, but those states have equivalent road types no matter what they are called. It's just a matter of categorizing them into Primary or Minor and that is what FC is supposed to help with as I understand it.

4. I experimented with changing a road type in Alabama on a route I frequent -- a 4-lane, 65mph rural state highway from minor to major to see if would help routing -- and it did. The problem is the change was not supported by adherence to Alabama's functional classification system (which varies by county...argh!), but by my personal knowledge. That's not good. I would say Alabama's FC maps are wrong, but another editor would come along and "fix" those roads so that they align with Alabama's FC maps and we'd be right back where we started.

5. FC will require more attention be paid newer editors to help them be successful.


Best,

Thank you, Sketch, for the effort invested in this. At present, I am an FC holdout for three reasons:

1. Ehud said, “Please, don’t do that,” after Andy’s FC briefing at the last NA Meetup.
2. I look at the areas where FC is in use, and do not see any reduction in “Wrong driving direction” URs compared to where FC is not in use.
3. It is a workaround to get Waze to do what it should do inherently. Road type should not be a routing factor per this post https://www.waze.com/forum/viewtopic.php?f=212&t=48543. Is not a claim of FC that road type does impact routing?

Never-the-less, FC mostly aligns with what I requested AL, FL, and GA editors do, which is:

Interstate/Freeway = Freeway
US-xx = Major Highway
SR-xx = Minor Highway
CR-xx = Primary Street

This does not impact routing any more – or less – than FC as far as I can tell, but has the advantage of being concise. For my experience, I wish Waze would just adopt Google’s routing engine and be done with it, but that’s beyond the scope of this discussion.

Best to you,

The way I see it, in this case, the local editor needs to justify their position. Something to the effect of "It's a minor highway because it connects between X & Y, both FC minor highways, has the same lane configuration as both of them & the same speed limits as well". That shows very similar Functional Properties of the road & is a justification for an upgrade.

I just got it to load in one click up here in CT... and it seems to be responding to the menu selections & zooming, etc... The legend indicates they are still using the Pre-2009 urban/rural split types.

Seattle also uses the FC map. One thing I have noticed is WSDOT's FC map changes some roads class when they go from Urban Area to Rural Area and Vice versa.
I can't find the legend/key for the WSDOT FC Map, do they different types between Urban and Rural areas? In 2009 US DOT removed the urban/rural split and simplified things. 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.

Same goes for Connecticut - no County Roads. There is also an entire series of unsigned state route numbers in CT as well - basically everything from CT-400 & up... I've been slowly removing references to those (almost all alt-names) as I've come across them. For more info on the unsigned road network in CT, see http://en.wikipedia.org/wiki/List_of_State_Routes_in_Connecticut

Yes, we're still waiting (since last meetup) for feedback from Ehud.

My main problem with typing by naming (i.e. US-## must be typed X) is that those roads (both US-## & SR-##) can vary from one lane in each direction with stop signs to 2-3 lanes each direction with traffic lights to full blown limited access highways... Each of those are drastically different types of road.

Yeah, that's disappointing. Did you include this example in the routing test feedback thread?

So much fun discussion! Did I miss any routing test users chiming in that the new routing code does a much better job of using mH and primary street, using speed data rather than pruning based only on road type?
