Low-cost, high-efficiency hardware implementation of smart traffic light system

In this paper, we propose a low-cost, high-efficiency hardware architecture for a smart traffic light system. Our design especially achieves high efficiency for traffic systems where motorbikes are used as the main means of transportation. The main contributions of the paper consist of: (1) proposing a simple approach for automatically adjusting the green light time based on the state of the optical transmitter-receiver sensor pairs, (2) proposing a new traffic light signal generation, i.e., all traffic signals including the light signals and countdown timer module will be integrated inside only one block by using addressable WS2812B LEDs, (3) proposing the hardware architecture for a smart traffic light system which saves energy, maintenance costs, and is installed and operated easily.
