(This paper introduces the use of the network information collection and management system in the intelligent transportation system, which has a master-slave structure. Among them, the host computer is a PC, and the slave is a signal collection system composed of 8031 ??single-chip microcomputer minimum system, A/D converter and sensors. The communication between the master and the slave is carried out through RS-485. For the control of traffic lights, the system adopts the neural network resolution method, and the use of neural network makes the system control with high accuracy.)
