Something showing the TFL proposals, and the LCC suggestion with a link to the LCC page, and details of how to contact assembly members might be good.
shrug just thinking off the top of my head here, but something people not involved can take away and discover the point of what you're doing and why is important, it moves you from a bunch of idiots holding up traffic for no reason, to a bunch of idiots holding up traffic for a reason. And people are more forgiving and interested when there is a reason, and they know about it.
