Here is a snapshot [1] of an example of a short segment that has a false
positive.  This is located in Okanogan County, Washington State, at the
intersection of State Route 213 and US 97. I've marked the section as
invalid.

 I saw this and I was really hoping it would be for how to tag hints for
data consumers about two way roads that were formerly one-way but still
have the lights set as a one-way green-wave.  In cities with declining
motor vehicle traffic, this is increasingly common, and going the direction
opposite the former one-way direction is a great way to hit a red wave.

Finding not so obvious tagging errors makes Traffic Flow Direction helpful.
This is good use of gps points.

Martijn - can you tell us how many traces you are using to indicate that a
way is oneway?

[OSM-talk] Traffic Flow Direction

2015-10-30 Thread Clifford Snow 
Martijn,
I like your new challenge, Traffic Flow Direction [1]

I am finding some false positives, typically short segments of road. Twice
I've see it between to side roads and once when the highway changed from a
bridge to a secondary with a side road just a short distance from the
bridge. Makes me wonder if there is something about short distances that is
triggering the false positives. The ones I've found are in Washington State.

Thanks for the great tool. I look forward to correcting a bunch of errors.

Clifford
