| RAMM Table: | Carriageway |
| Attribute: | Carriageway Type |
| Purpose: | To provide road categorisation that identifies different types of road sections (carriageways) that allow analysis to report on dual carriageway, roundabouts, ramps and other special types separate from normal single carriageway roads. |
| Value | Description | Photo Example |
|---|---|---|
| Standard Network | A standard network road is a regular two-way road with one lane in each direction, used for general traffic movement. |  |
| Dual Carriageway | A dual carriageway road is a road with two separate lanes or carriageways for traffic in opposite directions, usually divided by a median. |  |
| Roundabout | A roundabout is a circular road layout where traffic moves in one direction around a central island, used to manage intersections. Major roundabouts provide approaches that have splitter islands. |  |
| Ramp (On or Off) | A ramp is a short road section that allows vehicles to enter (on-ramp) or exit (off-ramp) a larger road, such as a highway. |  |
| Accessway | An accessway is a small road or driveway that connects properties or local roads to the main road network, often used for local or private access. |  |
