Tagging ideas for California

Since there are multiple governments involved in building/maintaining roads, and there doesn't seem to be usable correlation of what they call a road to the types used in OpenStreetMap, road types need to be done by judgment. The following guidelines are for urban areas, and are loosened for rural and tightened in dense urban to avoid making everything secondary or larger in an area.

highway=motorway - Access via on/off ramps with merge lanes, divided road of at least 2 lanes each direction. Called "Freeway". Speed limits generally 55MPH or higher.

highway=trunk - May have cross traffic, but traffic flow on the trunk always has the right of way. Speed limits usually 45 MPH or higher.

highway=primary - Three lanes or more each traffic direction. 35 MPH or faster. Handles large volumes of traffic.

highway=secondary - Two lanes of traffic each direction. 35 MPH or faster. Medium-high traffic volumes.

highway=tertiary - Lower traffic volumes on wide streets, or higher on narrow ones.

highway=minor - Single traffic lane each direction. 35 MPH or slower. (Note: This is considered by OpenStreetMap to be a deprecated feature. See the talk page for discussion.)

highway=residential - Single traffic lane each direction, abutters residential. Usually 25 MPH or slower. May have traffic bumps and other "traffic calming" measures.

If something has a state or federal highway number, it gets classified higher if there is a question.
