Summary |
The paper realizes multifunction traffic lights with colorful LED array. The hardware construction includes main module and secondary module, becoming a system. The lights planning, every module contains two screens. one is pattern, another one is read-second number. The main module primarily shows the lights of the crossing, and delivers the messages to secondary module at the same time. Secondary module receives the messages from the main module, and shows the lights correctly on the crossing. There are coordinated by the two modules at the same time, and let traffic safe on the crossing. Those modules are combined with Arduino, RGB control board、colorful LED array、wireless communication circuit. The traffic light has patterns to help color blind to understand traffic condition. The traffic light can conform some functions and have merits which can integrate orderless traffic lights. It can help vehicle and pedestrian to understand traffic condition; protect smooth traffic and safety. The paper can provide to refer the design of the traffic lights . |
