I am sorry, I don't want to offend you, FredBass.

But I think you misunderstood my point.
I do know how JSGME works, and in the past I was used to put JSGME-compatible mods into it's MODS-folder, and dis- or enable them the usual way.
But this patch itself adds a mod to the MODS-folder.
I think there should be a note in the patch-readme, that advices you to 1st disable the old light-harbor-traffic mod (through JSGME), before you apply the patch.
Then let the patch overwrite the old light-harbor-traffic mod that is already in the MODS-folder.
Otherwise - upon enabling the new light-harbor-traffic - you are creating backup over backup.
