Telenav/Mapping Projects/Europe/Paris&Montigny le Bretonneux
Description
To make OpenStreetMap more navigable and accurate in guidance, our mapping team is planning to start an editing project in Europe. By the end of April our team will start editing in Paris and Montigny-le-Bretonneux. We will focus on editing one ways, turn restrictions, road geometry and also validating the existing map by correcting keep right errors.

| City | Road Geometry(km) | Road Name(km) | Oneway(km) | Speed Limit(km) | Lane Info(km) | Turn Restrictions | Signposts |
|---|---|---|---|---|---|---|---|
| Paris | 2029.05 | 1752.40 | 1328.17 | 1303.54 | 396.94 | 387 | 10 |
| Montigny-le-Bretonneux | 167.48 | 128.70 | 76.05 | 56.89 | 26.66 | 12 | 3 |
The statistics were made with osm data from 03.17.2020 (https://grab.community.improve-osm.org/dumps/)
One ways:
We will add the direction of the ways (oneway = yes) where is needed and missing.
| City | Cases to review |
|---|---|
| Paris | 50 |
| Montigny-le-Bretonneux | 2 |

Turn restrictions:
We will add new turn restrictions relations where are needed with the help of OpenStreetCam and Mappilary.
| City | Cases to review |
|---|---|
| Paris | 1081 |
| Montigny-le-Bretonneux | 28 |

Integrity check and Keep Right
We will improve the existing data using tools like Integrity check and Keep Right.
