If you want to deal with highwaymen, you need the official guidance they are expected to follow. A lot of this is in Traffic Advisory Leaflets (TAL's) These use to be published in print and anybody could be on the mailing list free. It's now all on the internet. TAL 1/06 General Principles of Traffic Control by Light Signals is in four parts and is lengthier than most. This is the TAL general index.

Going back to my time working rotating shifts, I've always been conscious of the problems caused for riders by badly working traffic lights. The point about shift work is that at busier times heavy motor traffic can hide the fact that cyclists are undetected. The other thing besides knowing the guidelines is factual evidence rather than vague grumbling. eg We had a bus and cycle lane in Leeds which was on a detection system which only recognised buses and not cyclists. This couldn't be verified during the day because of the constant stream of buses, but outside bus hours, cyclists couldn't get a green. When I first raised this at a consultation meeting, a highwayman there to speak on another agenda item dismissed what I was saying but at the next meeting somebody who knew turned up and acknowleged I was correct.
