Abstract

With the increasing number of cars in suburban areas like Tarkwa-Nsuaem, expensive approaches to expanding road infrastructure are financially impractical for a lower-middle-income country like Ghana. Traffic accidents, causing 1.25 million deaths, up to 50 million injuries annually, and a global ratio of 18 deaths per 100,000 people, demand cost-effective prevention solutions for these suburban communities. This study proposes an ultrasonic sensor-based traffic control system using an HC-SRO4 ultrasonic sensor and an Arduino Nano with an ATMEGA 328P microcontroller. Simulated using Proteus 8 Professional and Arduino 1.6.7 software, the system optimizes traffic flow by eliminating the standard 60-second red light wait time. Vehicles on byways move freely unless a vehicle is sensed on the connecting highway, in which case the wait time is reduced to under 30 seconds. This low-cost, adaptive approach enhances road safety and efficiency, making it a viable alternative for traffic management in resource-constrained suburban communities.

Abstract

Exploring the potential of optical wireless communication for short-range audio transmission, this research investigates the design of a portable system leveraging the inherent benefits of light-based propagation, such as low power consumption, license-free operation, and enhanced security. While line-of-sight alignment is a key consideration in laser communication, this research outlines a practical approach to system development. A 650 nm laser diode serves as the carrier for the audio signal. The system architecture, comprising a transmitter and receiver, was initially designed and simulated using Proteus software. Each unit was individually implemented and tested to ensure optimal performance. Subsequent integration of these modules and careful line-of-sight alignment enabled successful audio signal transmission and reception. The audible output at the receiver is visually confirmed by a blinking speaker, demonstrating the feasibility of this optical wireless audio communication system. This work offers valuable insights into the design and implementation considerations for such portable applications.
