Begins with a description of the Motorway Control and Signalling System in operation in The Netherlands. The paper then focuses on the development of a new function of the system: the automatic application of variable speed limits in case of high traffic demand. The motivation for the proposed control measure is given, followed by a description of the form in which it is to applied, of the signalling system in which it is to be implemented, and descriptions of experiments both completed and expected. The system requirements control algorithm, and resulting system design are also described.
