Active Traffic Management (ATM) is a system used on certain motorways where gantry signs are computer-controlled to set a variable speed limit, open the hard shoulder as a running lane and limit the volume of traffic entering at junctions, with the aim of improving the flow of traffic (see http://www.cbrd.co.uk/indepth/atm/ for more detailed information about the Active Traffic Management system).
