Abstract
The environmental benefits offered by fuzzy logic for controlling real signalized
intersections have been discussed in this paper. The basic principle of fuzzy signal
control is to model the control based on human expert knowledge, rather than modeling
of the process itself. The design of a fuzzy controller for this system requires the expert
knowledge and experience of traffic control in formulating the linguistic protocol, which
generates the control input, to be applied to the traffic control system. The first
hardware installation was done in June, 1998. The fuzzy signal controller (FSC) has
worked all the time without problems. Some fine-tunings were made twice
concerning the traffic model in the first time and the extension sensitivity in the
second time. The received feedback has bee
