|Feature : Frontage road|
|A minor road running parallel to a higher-speed more major road.|
A frontage road (also access road, service road, parallel road, etc.) is a minor road running parallel to a higher-speed more major road, often in an urban setting. The frontage road is connected at some points with the major road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. A frontage road if often, but not always a oneway road.
How to tag?
Do not use the highway=*_link tag for the frontage road. Use one of the normal highway=* tags. As the frontage road is minor then the major road, it must also have a minor highway=* tag than the major road – often highway=residential.
Example: If the major road is “tertiary”, than the frontage road is not
“tertiary” neither “tertiary_link”. It has a minor type: can be “unclassified”, “residential”…
