Ego traverse junction
Scenario location: $FTX_PACKAGES/base_scenarios/scenarios/junction_family/ego_traverse_junction/
In the ego_traverse_junction scenario, the Ego traverses a junction from the in-road, passes through the junction, and exits from the out-road.
Actors
The actors associated with this scenario are as follows:
| Name | Description | Type | Depiction |
|---|---|---|---|
ego |
Vehicle under test | vehicle |
 |
Prerequisites
