Description
To make OpenStreetMap more navigable and accurate in guidance, our mapping team is planning to start an editing project in Europe. In July 2020, our team have started editing in Madrid. We will focus on editing one ways, turn restrictions, road geometry and also validating the existing map by correcting keep right errors.

Overall statistics
| City | Road geometry(km) | Road name(km) | Oneway(km) | Speed limit | Lane info(km) | Turn restrictions | Signposts |
|---|---|---|---|---|---|---|---|
| Madrid | 42128.5 | 21674.64 | 10899.38 | 5506.03 | 7703.73 | 5236 | 566 |

For this statistics we have used the dump from 17.03.2020
Improve OSM
One way
We will focus on adding missing one ways as well as on improving the existing data
We will add oneway=yes tag after checking the direction of the road using street level imagery as OSC and Mappilary, aerial imagery as Bing, Esri, and Improve OSM traffic flow direction, etc.
Also check: one way best practices and oneway
NOTES
• Pay attention to the direction of the way! Before adding the oneway=yes tag, make sure that the direction of digitization matches the direction of the oneway. If not, press "R" to reverse the direction and only after adding the oneway=yes tag.
• For roundabouts, the oneway=yes is implied, so it is not necessary to add it explicitly.
Cases to review for Improve OSM oneway
| City | Oneway cases |

| Madrid | 1285 |
Used dump
Turn restrictions
We will add new turn restrictions relations where are needed with the help of OpenStreetCam and Mappilary. For more info you can also check: turn restrictions best practices
Tags to be used:
• relations: type=restriction ; restriction= * ; except= *
• relations: type=restriction ; restriction:conditional= * ; except= *
• members: from,to,via
Cases to review for Improve OSM turn restrictions
| City | TR cases |

| Madrid | 1194 |
Used dump
Road geometry
To improve the existing data, we will focus on adding missing roads from valid sources.
We will follow the mapping scheme that is already used from the community: highway
Quality assurance
We will improve the existing data using Integrity Check and Keep Right tools.

For KR see: Keep Right
