Switching Control Methods for Expressway Ramp Metering Based on Hybrid Automaton Model

Article Preview

Abstract:

Based on the analyses of the traffic characteristic of urban expressway ramps metering, a hybrid automaton model for expressway ramp metering is set up and switching control methods of hybrid system is proposed using the hybrid automata theory. Compared with fixed-time ramp metering, Alinea control algorithm and fuzzy control algorithm in different traffic flows, and simulated in the Paramics traffic software, the results show that the method of switching control based on hybrid automata theory is more effective than a single control algorithm.
