@drkludge @Andygol @samely @rickmastfan67 lets move the broken relation conversation to https://github.com/mapbox/mapping/issues/224
Recently Mapbox satellite imagery in DC is rendered with 3-inch recent ortho imagery which will be a great spot to resume our turn lane mapping effort which we paused in August 2016. Created a turn lane mapping task for DC which we can target to hit next week. There is a total of 361 mapped turn lanes in DC.

There is data set with Intersection Points on opendata.dc.gov with 18,276 features - http://opendata.dc.gov/datasets/4b4155ee7bb443aa9a37a3f8e22a8abc_35
There is a possibility to mark turn:lanes
on the roads around ☝️ these points. For this purpose it is good to use https://osmlab.github.io/to-fix/.
@Rub21, is it possible to make to-fix
task for one of DC neighborhoods for trial run?
Doing turn lane mapping task for DC please pay attention on such cases 👇
and apply right oneway=yes
tagging and direction for the way
is it possible to make to-fix task for one of DC neighborhoods for trial run?
@Andygol before we do this, some clarifications;
@jothirnadh @Rub21 @samely
@maning
- The way to-fix works is that a mapper will be assigned a random intersection to work for every task. We lose context on the area.
Only in case if we add not only turn:lanes
but we add lanes=*
tagging along the way between intersection
- We may introduce conflicts when several people were assigned to an intersection that is part of a long road.
The same may happened even in standard workflow when way goes across two tasks
- We don't map turn lanes on residential roads, the intersection you linked include all intersections regardless of highway type. How do we filter this out?
There is possible just to skip it as we do it in to-fix
usually or before creating task in to-fix
find nodes that is near Major roads

I can help you filtering this data for Major Roads, 18,276 is a lot of items to do a skip.
@RichRico @Rub21 @samely it would be great if @mapbox/peru-office can take up this DC turn lane mapping task and target to complete it as soon as possible 🚀
@Andygol @maning , I just filtered the point for major roads, it reduces to 10,198 items. find all here, https://gist.github.com/anonymous/268daa5bd7f747c21d45a4cd1253a4f6.
The knife tool is now part of the auto_tools plugin, which can easily be installed through the default plugin installation. No "activation" needed. See http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Knife-tool
@jothirnadh @Andygol Today the ayacucho office began to work on the task of turn lanes in Washington DC
While validating turn lanes in DC, I found that the base data of DC is not aligning with new Mapbox 2015 imagery. Mostly in case of Major highways which are constructed recently.
This might be because the existing data is traced from outdated Bing imagery (2011) which drastically changed in time.
Mapbox-2015, bing-2011
It would be great if we can have a separate task to align major roads in DC city with Mapbox 2015 imagery to update the base map.

Great work @mapbox/team-data on adding and reviewing turn lanes in Washington DC 🎉 . Our team reviewed and added turn lanes based on the new 3-inch recent orthoimagery in DC. Do check it out.
During the course of this task, our team added ~2548 turn lanes in DC during a course of 3 mapping days with a total of 8 mappers working on the task. The total count of turn lanes in DC now is ~3200.
Please feel free to contribute and give feedback on our mapping processes on our mapping repo where we track all our ongoing mapping projects.
Great work in mapping turn lanes in DC 👏 . Continuing turn lane mapping quest, let's hit missing turn lanes in outskirts of LA covering Pomona, San Bernardino, and Redlands. Created a mapping task for this region which has ~582 existing turn lanes.
Ex:
Road mapped as bi-directional road with an existing relation

You can find the description of the workflow "How to split a bidirectional road to the road with separate ways in each direction" here - https://gist.github.com/Andygol/a2ff609bb4d71274245d51b1c253b832
dealing with relations ☝️
@mapbox/team-data if you are faced relation for a Public Transport route, ping me with links to it for extending workflow on such case.
Thanks for sharing the ^^ workflow @Andygol, @chtnha and I will do a trial run and post our findings soon before including it into our regular workflow 🙇 .
Route relations
, but finding roads not touched even if it is tagged with turn restrictions. Let's make sure the roads with turn restrictions are not skipped.route relation
for now, don't even map turn lanes in that roads.@mapbox/team-data do invalidate the blocks which fail to fulfill the above criteria and let the mapper fix them.
Guys when I was validating turn lanes on # 81 - Turn Lanes in Los Angeles outskirts- Chino, San Bernardino & Redlands found this error and solved it, as follow, according to the turn restriction
rules.
@Andygol @jothirnadh @RichRico
When we create dual-carriageways, make sure to update lanes
count for the created ways and not just in the way which has turn-lanes.
@mapbox/team-data do invalidate the blocks which fail to fulfill the above criteria and let the mapper fix them.
@mapbox/peru-office thinks that instead to invalidate the blocks, we shlould correct them, in this way we could reduce the time in finishing the task, because we aren't going to take extra time in reviewing by one person and validating again by another person. Also, instead to invalidate we could left a comment on the block with the kind of mistake we have corrected during the validation.

Great work @mapbox/team-data on adding and reviewing turn lanes in LA Exterior 🎉 . that were missing turn lanes in outskirts of LA covering Pomona, San Bernardino, and Redlands.
During the course of this task, our team added ~9,075 turn lanes in LA Exterior during a course of 5 mapping days with a total of 22 mappers working on the task. The total count of turn lanes in LA exterior now is ~9,657.
Paused. Wil revisit later.
