Intelligent Traffic Control System Based on DSP and Nios II

In view of domestic traffic, the traffic flow is increasing rapidly recent years, whereas the traffic control is deficient. This paper presents a design of intelligent traffic control system based on DSP and Nios II. Using dual-CPU, intelligent traffic control system combined with logic control in FPGA implements kinds of functions, which include cross-phase adjustment, exchanging and establishing related information, live human-computer interaction and remote control etc. The system works mostly at the mode of timing and multiple phases according to the user demands dynamically, thus it breaks through the bottleneck of traditional traffic signal controller, and can accomplish the control in complicated and diversified traffic. This paper gives the realization of hardware system as well as the software system. The experiment results show that the intelligent traffic control system can completely meet the requirements of modern traffic control.
