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.

Overall statistics

The types of roads that we are taken in to consideration are: motorway, trunk, primary, secondary, tertiary, unclassified, residential, living_street, service, track, road, ferry

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
