An Interval Type-2 Fuzzy Cellular Automaton Model for Traffic Flow
On the basis of Nagel-Schreckenberg model,this paper presents a modified fuzzy cellular automaton model for one-lane highway traffic.An interval type-2 fuzzy logic system is designed to evaluate the randomization parameter of a vehicle based on the spatial headway and speed difference.Some basic qualitative results and the fundamental diagram of our new model are got through computer numerical simulations.The experimental results show that our new model is able to reproduce some of the real macroscopic traffic characteristics such as stop-and-go waves,hysteresis and metastability phenomena.
