In an effort to improve the navigability of Los Angeles, Miami, Dallas, Chicago, San Francisco, Las Vegas cities, the Lyft OSM Data Curation Team is undertaking efforts to update key road features that include turn restrictions for vehicles, time-based restrictions, and exceptions for different types of vehicles. The missing turn restriction features were identified algorithmically.
To keep the quality of our map edits at a high level of accuracy, we apply a quality control (QC) process on 100% of tasks. Each task will be QCed before being published to OSM. Our QCers check restriction possibilities on the scoped relation. If the curator accidentally added wrong or unnecessary turn restrictions, the task will be returned to the curator to correct it based on the QCer’s comment.
**Ground Truth Resources***
Street level imagery (Bing, Mapillary)
Aerial imagery (Mapbox, Digital Globe, Maxar)
Proprietary sources of aerial and street level imagery
OSM changesets will be submitted abiding by the OSM Changeset Guidelines.
