How to combine paths that are stacked on top of each other?

Sometimes when I use image trace for complex images it produces multiple layers of paths, sometimes in which paths in the exact same line are "stacked" on top of each other - in other words the trace process has produced multiple shapes and when you work with the paths (which I need to do to use in a vinyl cutting process) there are doubled lines in different sections. I've tried to explain with the attached photos - the first one shows one layer/path, the next with that one hidden and another highlighted that covers much of the same area. I would like to be able to combine/merge/flatten these paths into one rather than trying to wade through the layers and hand edit them. Is this possible?
