FPGA Implementation of an Intelligent Traffic Light Controller (I-TLC) in Verilog

2024-01-24 · Apoorva Banerjee

The objective of this paper is to design and implement an intelligent Traffic Light Controller system for a four way road intersection. The design is carried out using Verilog, and the hardware is implemented on a FPGA. The chosen intersection involves a 'main road' (heavy traffic flow) and a 'side road' (less traffic flow), which is equipped with sensors to detect the presence of traffic or pedestrians. The functionality of the system has undergone thorough verification through simulations conducted in the Xilinx ISE Design Studio software environment. Furthermore, it has been physically deployed on a Xilinx Spartan-3E FPGA board xc3s500e-4-fg320. A traffic light controller can be realized through the use of a microcontroller, Application-Specific Integrated Circuits (ASICs), or Field-Programmable Gate Arrays (FPGAs). FPGAs however offer significant advantages in terms of re-programmability, speed, and parallel processing capabilities, making them ideally suited for implementing complex, adaptive logic required by smart traffic management systems; thus, making this model of TLC extremely adaptive and cost efficient at the same time as compared to other existing models with reduced hardware usage and delay constraints.
