Analysis settings with traffic lights using fuzzy logic mamdani centroids (case study of Makassar Bawakaraeng Mountain crossroads)

Traffic lights are a form of intersection traffic controlling operations are the most commonly applied, especially in urban areas. Traffic lights at the intersection plays an important role in determining the smooth distribution of vehicles on the road, so traffic light system of regulation that would better facilitate traffic flow on a set path. Goal of Settings Logic Analysis of Traffic Lights is based on fuzzy logic: First, Knowing membership functions of input and output of vehicles coming vehicles and output of vehicles at the intersection of Mount Bawakaraeng and duration of green light output in the fuzzy set. Fourth, Knowing the duration of effective green light by using fuzzy logic at the intersection of Mount Bawakaraeng. In this paper there are three membership functions, namely: input membership functions of the arrival of vehicles, vehicle output membership function and membership function duration of green light output. Each membership function is formed by classifying the input and output fuzzy sets by using the mamdani triangle curve representation. To input the number of vehicles coming = d. To iutput the number of vehicle = V. Membership function of output duration of green lights = l. Results Discussion that the duration of effective green light at the intersection of Mount Bawakaraeng Makassar when re-employment, namely: For the arrival of the vehicle 17 and the output of the vehicle 16 so that the effective duration of green lights 50 seconds, for the arrival of vehicles 17 vehicles 18 and outputs the duration of green lights effective 51 seconds, for the arrival of 19 vehicles and 17 vehicles output then the effective duration of green lights 51 seconds, for the arrival of the vehicle 20 and the output of the vehicle 18 so that the effective duration of green lights 54 seconds, for the arrival of 21 vehicles and 19 vehicles, the duration of the output green light Effective 57 seconds. Conclusion First, Know the membership function of input and output number of vehicles coming vehicle at the intersection of Mount Bawakaraeng by Veterans in Makassar and the output duration. Burning green light, so the third relation the input variable arrival of vehicles, vehicle output and the output of green light duration is closely related to each other, Second The results obtained indicate the duration of effective green light at the intersection of Mount Bawakaraeng with Veterans at the road when people come home from work.
