Telenav/Mapping Projects/United States/Washington Oregon California Arizona Nevada
To make OpenStreetMap more navigable and accurate in guidance, our mapping team started an editing project in United States.
In this project we will focus on editing oneways, turn restrictions, road geometry and also validating the existing map by correcting errors from 5 different states (Washington, Oregon, California, Arizona, Nevada)

Overall statistics
In the overall statistics for the 5 States, we have considered the following types of highway: motorway, trunk, primary, secondary, tertiary, unclassified, residential, living_street, service, track, road, ferry.
For each feature, our team has created some statistics:
| City | Road Geometry(miles) | Road Geometry without link (miles) | Road Geometry Gap (miles) | Road Name(miles) | Road Name Gap(miles) | Oneway(miles) | Speed Limit(miles) | Speed Limit Gap (miles) | Lane Info(miles) | Lane Info Gap(miles) | Turn Restrictions (count) | Bridge(miles) | Tunnel(miles) | Surface | Surface Gap (miles) | Roundabout | HOV | Railway crossing (count) |
