When traffic signal is exported to Apollo format (.xml) from RoadRunner, there is no overlap generated.

In RoadRunner, I create a traffic signal and link it to a stop line. Then it is exported to Apollo format (.xml). In xml file, the traffic signal is descriped in element <signals>, but no related overlap infomation is indicated. This information is important in Apollo.

Hi @Wanyi Xiong,

I understand that you are trying to export a custom traffic signal and the related data is not visible in exported file.

The Apollo exporter uses a configuration XML file to map RoadRunner props, signals, signs, and markings to the appropriate <object> or <signal> "id" and "subtype".

To Exporting a Custom Prop or Signal you can follow the below steps:

1. Copy the ApolloAssetData.xml file located in the RoadRunner install location under AssetsInstall/ResourceAssets to the Project folder in your project (next to the Project.rrproj file).
2. Open the new ApolloAssetData.xml file in a text editor.
3. Add entries for new objects, markings, or signals.
4. Save your file and export an Apollo file.

You do not need to restart RoadRunner after creating or modifying the ApolloAssetData.xml file.

For more information kindly view the following documentation:

Hope this helps!

Thank you
