This chapter summarizes Australasia’s (Australia and New Zealand) practice on fixed-time traffic signal control at an isolated intersection. A brief overview of traffic signal control followed by national standards and guidelines used for planning signal timings and infrastructure is presented. Thereafter, general procedures for fixed-time and isolated signal timing design along with commonly used terminologies and an illustration of some major timing parameter calculations are introduced. Detailed information on the movement-related methods followed in Australia and New Zealand which are different from phase-related methods is discussed. A method used in the estimation of saturation flow, especially in the presence of an opposed turn or short lane, is described. Further, critical movement analysis, used for practical timing design of an isolated intersection, is presented, with an example for a typical intersection layout.
