Oklahoma still has a very large of unreviewed TIGER ways, much of which added medians where there are none, or omitted medians. Additionally, turn lanes and lane counts have tended to be inaccurate from the previous lane tagging challenges, and turn lane information has not been added. Oklahoma County is the most populated county in the state and is one of the most prone to natural disaster.
Let's make Oklahoma the best mapped state in America for road navigation by the end of the decade!

bicycle:lanes(:forward/backward/both_ways)=*, etc as necessary based on ground knowledge or visible in aerial information.
Use common sense on ways where the imagery shows road construction, lane configuration may have changed or is not possible to infer at this time without a ground survey. Digital Globe Premium currently has the highest resolution and most recent imagery available, however, you may need to work on alignment of the imagery.
Where no lanes exist on the ground but are tagged, remove lane tagging (this is rare; make sure that it's not just really faded; residential streets are the most common type with lanes tags added without lanes on the ground).
Add stop nodes, yield nodes, crosswalk nodes, traffic signals, etc as appropriate where these items are visible from the air. Stop bars and shark teeth indicate presence of a stop or yield sign. Where high enough resolution is available (particularly near the freeway end of freeway onramps), triangle shaped shadows can often indicate the presence of a yield sign.
Add streets, alleys and parking aisles where missing. The TIGER 2017 imagery layer can be a source of names where missing.
