Description

In this project, we will map turn restrictions in Detroit, Michigan area, and we will focus on adding missing restrictions as well as improving the existing data in OSM.

How to map

We will follow the mapping scheme that is already used by OSM community as it is described on this page:

We will also follow the rules that are already used in Detroit for turn restriction mapping:

We’ll also keep in mind to add any other useful information that are related to turn restrictions (e.g.: oneways, roads under construction etc.)
We will use OpenStreetCam and Mapillary as sources.

Who will be involved

We worked on this issue since middle of May and we are still in progress. We succeeded to review all existing restriction, and we corrected them if it was necessary. Also, we used OSC images to add new restrictions in Detroit area.
We focused on the three most important counties: Wayne, Oakland and Macomb, but we also edited in the five other 5 counties near Detroit: Monroe, Genesee, Washtenaw, Livingston and Lenawee.

Breakdown stats for correcting existing turn restrictions in Detroit area:
