Fuzzy traffic signal control in major arterials

The opportunities offered by fuzzy logic for controlling traffic are the subject of our FUSICO-research project in Finland at the Helsinki University of Technology. In the previous studies of FUSICO-project, traffic signal control based on fuzzy logic has successfully been tested in urban intersections. The promising results of simulations and field installation suggest that the fuzzy control method would be competitive also in high-class arterial roads with high safety and efficiency demands. Encouraged by this, we are developing a fuzzy control method ITCARI for arterial intersections. The pilot version of ITCARI-control is installed at an intersection in the city of Tampere, and the field measurements will be done during summer 2001. First simulation studies of the Tampere case indicate competitive performance of the fuzzy control method on arterial roads.
