Thanks for that tip; obviously I was wondering about patents. But I would like to see the idea implemented. For that to happen, somebody would have to pick it up and run with it. Like, somebody would have to pitch it to transport authorities; but I'm no salesman. Also, the idea is fairly complex; it would probably involve lots of patents. It would be better for the idea to die in my brain, than for me to get a score of patents, none of which is ever implemented. That would be a waste of my time and trouble. The contents of that book mention NDAs, which I hadn't really thought about; I could discuss these ideas with some suitable company under the terms of an NDA, I guess. Next problem is: how to find a "suitable company" to talk to. Thanks again; I didn't know there were books on how to do a DIY patent.
