Modeling and Signal Control of Single Intersections by Fuzzy Logic Controller
[ Ehsan Azimirad ] - The student of Ferdowsi university of Mashhad [ Naser Pariz ] - PHD Proffessor in Ferdowsi university , Electrical College
State - space equations were applied to formulate the total wait time vehicles in traffic network at a single intersection in thes paper. The signal comtrol of a single intersection was then modeled as a discrete time optimal control problem . However , the results of qualitative analysis were used to design a fuzzy signal controller. The fuzzy logic controller (FLC) presented in thes paper simulates the control logic of experienced human traffic comtrollers such as polece officers. Simulation results open and close loop intersection show that the controller substantially reduces the total wait time vehecles compared to fixed - time comtrol.
