MATLAB toolbox of fuzzy logic is used to solve the problem of freeway on-ramp metering. The components and design steps of a fuzzy logic controller are formulated, and MATLAB toolbox of fuzzy logic is introduced. The fuzzy logic on-ramp controller is designed according to traffic parameters measured in the upstream and downstream of a freeway, and simulation experiment is carried out. Simulation results show that such an approach is practical and effective. It can avoid traffic jams and congestion on the mainline, and make the vehicles travel more efficiently and safely.
