,Traffic signal design experimental purposes thread: multi-threaded design, synchronization mechanism to design a title intended to traffic lights categories: (1) variables: location, color (red, yellow and green), showing time (seconds). (2) Method: Cut (3) for signal. Create and start two threads (east to west, north-south) to run simultaneously. Experimental requirements (4) design thread. (5) Schematic diagram of the interface design of the junction signal. (6) further in each direction, the signal is divided into three kinds of driveway lights: turn left, go straight and turn right. (7) in accordance with the time flow of fuzzy control.
