在建立高速路交通流模型的基础上，结合模糊控制理论设计出了基于模糊逻辑的入口匝道控制器．该控制器根据期望密度和实际车流密度的误差和误差变化量，决定入口匝道的调节率。仿真结果表明，该控制器具有较好的稳态和动态性能，能避免交通拥挤，从而提高主线的通行能力。

Based on the dynamic model of the freeway traffic flow and in conjunction with the fuzzy logic theo- ry, the ramp controller by using fuzzy logic is designed. The ramp metering rate is determined by the fuzzy control based on the density tracking error and the error variation. Simulation results show that the ramp controller is practi- cal and effective. It can avoid traffic jams and improve the mainline passing capability.
