The development of the microprocessor-based traffic signal controller for use at urban traffic control installations has enabled the engineer to design traffic-signalled intersections with a far greater degree of flexibility. There are a number of computer programs which will calculate the capacity of traffic-signalled intersections and these are usually adequate for dealing with stage-based controllers. However, in order to model a microprocessor controller, a more accurate computer model is required to enable any minor alterations in the controller design to be reflected in the capacity of the junction. In order to achieve this the junction has to be modelled in two different ways, using a controller model and a traffic model. This article describes a computer program (LINSIG) which allows the engineer an opportunity to design the controller to the MCE 0141 specification, test the design and then compute the junction capacity. By altering the controller model or the geometric parameters, various options can be tested. The two models and the way in which they interact are explained. (TRRL)
