Perspective on traffic control : aspects of freeway control, intersection control and the control of transit flow in the Netherlands. Paper presented at the 1988 TRB Annual Meeting, January 1988, Washington D.C., U.S.A.

The first part of this paper deals with the control and signalling system for motorways. The second part gives some insight into the traffic conditions in urban areas and of the Dutch method of intersection control by means of dynamic multiphase control schemes. The third part deals with operational control of transit flow. The fundamentals o TRICOPT are explained, and the effects are calculated on the efficiency of this control for the required fleet sizes.
