Can the hdmap library be used to generate traffic lights（signals） in a scene? If possible, which interface of hdmap should be used?Is it possible to use the hdmap library to build traffic lights in a scene, export it to opendrive format via Roadrunner, and control the dynamic changes of traffic lights by writing openario? grateful!

Hi 鹏,

I understand that you want to generate dynamically changing traffic lights (signals) in a scene and export it to “OpenDrive” format using “RoadRunner”.

Here are some resources that might be useful for the required task:

• To generate the scene: “MATLAB example to generate RoadRunner Scene with Traffic Signs Using Recorded Sensor Data”: https://www.mathworks.com/help/driving/ug/generate-scene-with-traffic-signs-using-recorded-sensor-data.html
• To export the scene to “Opendrive” format:

1. Use “export” function which exports the actors in a driving scenario to the ASAM OpenDRIVE file format: https://www.mathworks.com/help/driving/ref/drivingscenario.export.html
2. MathWorks documentation to Export to ASAM OpenSCENARIO: https://www.mathworks.com/help/roadrunner-scenario/ug/export-to-asam-openscenario.html

• Controlling “RoadRunner” Programmatically: https://www.mathworks.com/help/roadrunner/ug/create-cpp-client-for-controlling-roadrunner-programmatically.html

I Hope this helps!
