Abstract
Traffic jam is one of the big problem happened in a big city such as Jakarta and Bandung. Sometimes the traffic jam is caused by the inappropriate traffic light time control. This paper describes the prototype implementation of traffic light control system by analyzing the image condition of the street captured by camera. The digital signal processing algorithm and the time of the traffic light is controlled by a STM32F407ZG Microcontroller. The size of Random Access Memory (RAM) is limited, so an additional external RAM is used in this research. The system input is 120 x 160 pixels of road image which already stored in the SD Card. A digital signal processing is used to determine which road has more traffic, and then the system will adjust the time of the traffic light based on the calculation.
