FUZZY LOGIC BASED TRAFFIC LIGHT CONTROL DEVICE Russian patent published in 2024 - IPC G08G1/01 G08G1/08 

FIELD: physics.

SUBSTANCE: invention relates to computer engineering and can be used to control traffic. Traffic light control device based on fuzzy logic comprises two video cameras and a microcontroller, which includes a fuzzy logic unit, two units of membership functions, a unit for calculating degrees of validity and a unit for outputting a control signal. Two video cameras are connected to inputs of the microcontroller, the outputs of which are connected to inputs of units of membership functions connected to inputs of the unit for calculating degrees of validity. Outputs of the unit for calculating degrees of validity are connected to inputs of the unit for truncation of membership functions connected to the defuzzification unit. Outputs of the unit of output membership functions are connected to inputs of the defuzzification unit. Output of the defuzzification unit is connected to the input of the first timer, the outputs of the two timers are connected to the inputs of the control signal output unit of the microcontroller, the outputs of which are connected to anodes of light-emitting diodes, the outputs of which are grounded through resistors.

EFFECT: enabling control of traffic lights based on fuzzy logic, which adjusts the delay time of traffic lights depending on data on the number of cars and pedestrians at the intersection.
