Can animation help people understand their transit options? The Rotherham Metro Borough Council in the UK has done some simple "map movies" that highlight the paths followed by buses and trains. Here's a still:
As they stand, they're limited in usefulness, as the icons move along the routes with no indication of frequency. They certainly do advertise complexity, which is accurate; this looks like a very complicated network.
But it's easy to imagine taking this to the next step, showing by animation the scheduled paths of all the services in a transit system. This would be especially helpful in helping citizens understand pulse systems, where the integrated scheduling pattern is an essential part of how the network gets you where your going. Now that I think of it, I'm pretty sure this has been done, but I've never seen it on a public information website, which is the obvious next step.
