A real-time dynamic intersection signal control design method comprises the following steps: acquiring information of each vehicle entering each lane in a current signal period of an intersection, andcalculating the current traffic flow in real time according to the information; and then, calculating the optimal period duration of the next signal period and the green light distribution of each phase according to the real-time traffic flow so as to adapt to the change of the road environment in real time and reduce the total delay time of road vehicles. A real-time dynamic intersection signalcontrol design system comprises an AVI device and a central processing unit, and the central processing unit is in communication connection with an intersection signal lamp controller. The AVI devicecomprises a reader-writer used for reading a radio frequency tag of a vehicle, and a data transmission unit used for transmitting data to the central processing unit. According to the invention, intersection signal control can be dynamically adjusted in real time, the traffic efficiency of vehicles at the intersection is improved, and reasonable allocation of urban traffic road resources is realized.
