Its all just an idea... but a good one! Excellent visualization! diplomod

very nice... they do something like this in a few of the outdoor malls in the US... they run them as large led screens with scenery and jets and stuff flying by... cool concept to do it on the roof of a tunnel... perhaps there is a way to get the lights running at a certain speed down the tunnel to help control the speed of traffic... Not sure about the advertising or scenery thing as it would take the drivers concentration off driving. They have a big thing about billboards here in Canada and how the ones with scrolling text or TV style commercials distract drivers. howman

They have something similar in Las Vegas on Fremont Street. http://www.youtube.com/watch?v=4t9gMelZlpA LED Head

but the difference here is in the use and in the realization AND video clips do not really promote the concentration of a motorist ;-) hartymd3

I mean video clips like in Las Vegas hartymd3

Thank you LED Head, i wasn\'t sure where I saw them... only saw a clip of them on TV ages ago... Figures it would be Las Vegas. lol. howman

It is a nice idea, but I think it will be too costly on public transit system. cybortek
