Conference paper


The opportunities offered by fuzzy logic for controlling traffic are the subject of our FUSICO-research project. The specific goal of this study was to compare the differences in various traffic signal control algorithms when simulating two consequent one-way intersections with no turning traffic. The compared algorithms used in the simulations were coordinated fixed-time signal group control, traffic-actuated gap seeking non-coordinated signal group control, traffic actuated fuzzy logic signal group control (FUSICO) and a combination of standard traffic actuated control and FUSICO-controller. This study was our first attempt to use fuzzy methods in coordinated traffic signals. The results were promising. All previous results of FUSICO-project have indicated better overall efficiency than traditional vehicle-actuated control.
