Specifies the directionality of a road used by a TerrainAccessOperator or TerrainRouteOperator.
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CEOperators assembly)
Syntax
public enum RoadDirectionalityValues
| Value name | Value | Description |
|---|---|---|
| OneWayReversed | 0 | A one-way road, where the travel direction is the opposite of the node order in the road line geometry. |
| OneWay | 1 | A one-way road, where the travel direction is the same as the node order in the road line geometry. |
| TwoWay | 2 | A two-way road. |
Remarks
The value of the property TerrainAccessOperator.RoadDirectionality or TerrainRouteOperator.RoadDirectionality is normally an attribute variable that depends on road attributes; the attribute variable could use table lookup or an expression.
If it is enough to use a single road attribute, table lookup can be used. The following example should work for a road dataset from HERE:
 |
If two or more road attributes are needed, an expression must be used, and the Expression Syntax requires you to write the integers that represent the enumeration values. For example, let us imagine a road dataset where the directionality must be fetched from two boolean attributes: every road has a TWO_WAY attribute that can be True or False, and any road where TWO_WAY is False must also have a ONE_WAY_FORWARD attribute that can be True or False. Then you could write the following expression:
