Description: Digital electronic technology course and design of traffic lights. The design of traffic signals to control circuit to be able to apply to a trunk road and a branch from the trunk of the convergence point of intersection are formed. Able to do the main and branch roads are not exactly the same time, traffic lights flashing, the green light to red light in the process of transition to the transition with a yellow light, making the process of moving vehicles have enough time to stop. Also called in the main, supported the establishment of a group of roads each time display, can display the corresponding red, yellow, green countdown. VHDL language can be used rational design system function, so that the conversion has a red, yellow, green precise time interval and the conversion sequence
