Traffic light control is a challenging problem in many cities. This is due to the large number of vehicles and the high dynamics of the traffic system. Poor traffic systems are the big reason for of accidents, time losses. This system proposed, in this paper aims at reducing waiting times of the vehicles at traffic signals. Traffic Light Control (TLC) system also based on microcontroller and microprocessor. But the disadvantage of with microcontroller or microprocessor is that it works on fixed time, which is functioning according to the program that does not have the flexibility of modification on real time basis. This proposed system using FPGA with traffic sensors to control traffic according requirement means designer can change the program if it require and thus reduces the waiting time. The hardware design has been developed using Verilog Hardware Description Language (HDL) programming. The output of system has been tested using Xilinx. The implementation of traffic Light Controller also through Application Specific Integrated Circuit. But implementation with FPGA is less expensive compared to ASIC design. This paper presents the FPGA implemented low cost advanced TLC system. Coding of the design is done using Verilog HDL and the design is tested and simulated on Spartan-3E FPGA development kit.
