Concurrencies starting/ending at a hidden waypoint

[Jim]

Another issue has arisen while I'm working on my graphs of our highway data where something I assumed was impossible happens quite a bit.

The assumption: a concurrency cannot start/end at a location occupied only by one or more hidden waypoints.  It is possible to have an endpoint of a concurrency at a location where at least one waypoint is visible - see Si's example of I-22/US 78 at what will some day be I-269.  That I don't have a problem with.

My intended use of the assumption: there must be exactly two unique places you can go from a location that is occupied by only hidden waypoints.

What I found: when this assumption is broken, it can be a symptom of a broken concurrency.  For example see the US20/MA8 example below.  They use different coordinates for the eastern/southern end of their concurrency.

Not urgent, but if you see things that appear to be in your regions, could you have a look through for possible broken concurrencies indicated by the list of error messages I'm generating, shown below?

Could the list mention the regions that the errors are in?  Would make it a lot easier to ID any problems in my areas.

Ok, I've figured out both of these errors.  It seems that when @mapmikey was creating the SC files for that state, he didn't (at least here) copy the coordinates out of the US-321 file for the start/end intersections along this multiplex with SC-34.  Same type of error with the US-221 one.  I'm working on fixing both at least right now. (Pull Request #644)

However, I would recommend to @mapmikey to double check all of the other start/end locations for multiplexes of State Highways w/ US Highways to make sure everything is synced so that the concurrencies are properly triggered.

Thanks.  I have the region information when I generate the messages.  I'll add that in and update this post the next time I run my graph generation.  I plan to spend a lot of time with it today, so that should be able to happen soon.

I still have plans for a better "near miss" system.  Once I'm done with my current efforts on graph generation, that might make sense to tackle next.

Thanks.  I have the region information when I generate the messages.

Good - there was one of mine that I couldn't find (done about half now).

Here's the new list.  Regions are readable but I messed up something and didn't get human readable highway system names.

Further note on this.  When I build my waypoint names for colocated points from multiple routes, one of the simplifications I apply is that if all labels are hidden, I arbitrarily choose one of the labels even if the hidden labels are different in different routes.  Sorry that that might make it a bit more complicated to figure out what's going on.

I'm hoping some of the things currently or soon to be in the works will make it easier for us to find broken concurrencies and other data problems.  I know most (all?) of you don't care if intersections line up, but that's a goal of mine.  I hope to fix those as well as concurrencies.

Best Practice, IMO. Remember the parable of the ME24 relocation in Brunswick.

These are also now flagged as datacheck errors, but only in the test DB for now.  See errors shown as "HIDDEN_JUNCTION".  The last field tells you how many graph edges leave the point, indicating a problem.
