Description

Create a script that takes scenarios from the SafetyPool database as input and bridges the gap to the SSv2-supported format. A reference for the compatibility differences is available here.

Assume that the road and lane IDs to be converted are provided in a csv file, in the format below:

Road ID (OpenDRIVE)	Lane ID (OpenDRIVE)	Lanelet ID (LL2)
0	0	0

Ideally, the script shall perform the conversion of the scenario and execute it with autoware in one go.
List up all inputs required to run the script and provide the information in the task.

Purpose

To facilitate the execution of any scenario from the SafetyPool database using SSv2.

Possible approaches

The following differences must be bridged:

• Replace minor unsupported features by others, supported by SSv2
• Assign a route to each entity in the scenario #126
• Add pass/fail criteria #127
• Convert OpenDRIVE lane references to Lanelet2 lanelet IDs #128

Definition of done

This task can be closed when all sub-tasks listed are completed.

To better manage the progress of the SafetyPool - SSv2 integration task moving forward, this will be treated as a separated effort from the map conversion in the FY26 roadmap.
