基于模糊控制的入口匝道智能控制方法

Abstract

Abstract:

Based on the dynamic model of the freeway traffic flow and in conjunction with the fuzzy logic theory,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 practical and effective.It can avoid traffic jams and improve the mainline passing capability.

Key words: fuzzy theory;intelligent control;freeway;ramp
