Restricted crossing U-turn traffic control by interval Type-2 fuzzy logic

The paper presents a novel approach to RCUT control, based on the interval Type-2 fuzzy system (IT2FS). RCUT design, among other various alternative intersections, proposes dislocation of left and through movements from the main intersection for an increase in safety and efficient traffic conditions. This concept assumes the rise of two new U-turn intersections downstream from the main intersection that can be controlled by traffic lights. RCUT design is justified when U-turn traffic demands, along with demands from and to minor streets, are significantly lower than arterial street ones. The semi-actuated traffic control seems the most appropriate control mode that should be applied at the RCUT. Evaluation of semi-actuated traffic control based on IT2FS is compared with other traffic control modes. The results show that semi-actuated traffic control, based on IT2FS, can generate statistically better results than other well-known controls.
