Abstract: A monochrome OLED display module is introduced as the human-machine interface display of the traffic signal. The module resolution is 128×64, and it has 16 levels of grayscale text and picture display. The designed display control scheme uses ARM9 as the processing chip, and can embed scientific algorithms to effectively control traffic flow. This intelligent traffic signal system can not only provide a good human-machine interface, but also adapt to the harsh outdoor environment, and can also control traffic flow in multiple phases and multiple time periods.
