FPGA-Based Dual-Mode Traffic Lights System Design

The Red-Green light system is an important traffic control system, widely used in urban traffic management. Traffic light control systems need to achieve automatic control function at the junction changes. Traffic lights control system designed by single-chip computer work at a single mode, it is not easy to be upgraded or change device size. The reliability is low, slow and difficult to adapt the traffic flow at different times of the daily changes. Dual-Mode Traffic Light Control System based on the different times of intelligent control of traffic lights-off time for the various road junctions improves the efficiency of the junction scheduling. FPGA Design Based on dual-mode traffic light control system has a simple circuit, high reliability and computing speed, scalability, as well as reconfiguration of good characteristics.
