A Logic of Traffic Light Controller Modelled and Analyzed by Statecharts
Tso Hsien Liao, Yi Sheng Huang · Key engineering materials · 2011
Statechart has been utilized as a visual formalism for the modeling of complex systems. It illuminates the features on describing properties of causality, concurrency and synchronization. In this paper, we try to describe the behavioral of the traffic lights by using Statecharts. We use Boolean function to make the traffic light controller behavior in a certain way. This paper used Boolean function to analyze the models which are modeled by using Statecharts. Their formalism provides a clear means for presenting control logic. Finally, an example of traffic light controller system is examined successfully.
