#### Access tag mapping

The `motorcar`, `bicycle`, `foot`, and `horse` attributes are derived from OpenStreetMap access tags using the following mapping:

| OSM tag value | Mapped to |
| ---------------- | :-------- |
| `yes` | yes |
| `designated` | yes |
| `permissive` | yes |
| `customers` | limited |
| `destination` | limited |
| `agricultural` | limited |
| `forestry` | limited |
| `delivery` | limited |
| `discouraged` | limited |
| `permit` | limited |
| `dismount` | no |
| `military` | no |
| `private` | no |
| `no` | no |

Other values are removed and not considered when evaluating access tags.

For each access type (motorcar, bicycle, foot, horse), the first matching OSM tag in the following priority order is used:
- `motorcar`: {{< tag motorcar >}}, {{< tag motor_vehicle >}}, {{< tag vehicle >}}, {{< tag access >}}
- `bicycle`: {{< tag bicycle >}}, {{< tag vehicle >}}, {{< tag access >}}
- `foot`: {{< tag foot >}}, {{< tag access >}}
- `horse`: {{< tag horse >}}, {{< tag access >}}

If no access tags are present the property is not present. Access is only evaulated for {{< tag highway >}} objects; railways and aeroways do not have `motorcar`, `bicycle`, `foot`, or `horse` properties.
