Abstract
Purpose of research. Development of a smart traffic light control system based on fuzzy logic with the ability to adjust the time intervals of traffic light signals depending on the traffic situation.
Methods. The definition of input variables for a fuzzy logic control system of smart traffic lights is performed using a vision system. The proposed method of controlling a traffic control device is based on a fuzzy inference system and contains several stages: determination of clear input variables, fuzzification of the values of input variables, aggre-gation of data based on fuzzy rules, defuzzification of values and determination of the delay time of the permitting traffic light signal.
Results. According to the proposed fuzzy model, a device that simulates the operation of a smart traffic light control system was developed. The device is assembled on the basis of the Arduino Uno controller. The developed specialized software model was patented. The number of the certificate of state registration of the computer program "Software for traffic light control based on fuzzy logic" is 2021661796.
Conclusion. The results of experimental studies show the high efficiency of the smart traffic lights in a daily cycle. The program successfully copes with the assessment of the traffic density of cars and pedestrians, adjusting the operating time of traffic lights proportionally. It is proved that the implementation of the developed smart traffic light control system makes it possible to ensure the safety and convenience of road traffic for all road users.
