Dynamic Street Light with Speed Range Display

Engineering Project

2018

Index

Bangladesh faces three significant challenges: electricity shortages, traffic congestion, and road accidents. These issues strain the country's resources and hinder its development.

In 2018, while pursuing a degree in Electronics and Telecommunication Engineering at RUET, I was motivated to address these problems. I developed a project that aimed to tackle these interconnected challenges: traffic congestion, road accidents, and energy inefficiency. Professor Md. Munjure Mowla (Ph.D., Wireless Communication), recognizing the project's potential, offered his guidance and support. This project

Addressed these three major problems and provided one unique (before 2019) idea to solve those three problems in a single board

Identified Problems

Traffic Jams and Road Accidents: While numerous factors contribute to traffic congestion and road accidents, this project focused on addressing two key causes:

Speed Imbalance: When multiple vehicles in the same lane travel at inconsistent speeds, it creates an uneven flow of traffic, leading to congestion and potential accidents.
Limited Visibility: Poor weather conditions, such as rain or fog, can significantly hinder drivers' ability to see and react appropriately, increasing the risk of accidents.

Energy Loss: The project also aimed to tackle a major source of energy inefficiency in Bangladesh's street lighting system: Manual Operation.

Currently, street lights are often left on during the day and switched off at night, resulting in wasted energy. Additionally, manually managing lights becomes inconvenient during unpredictable weather conditions like rain or fog.

Proposed Solution

Speed Exhibitor:
This project proposes a dynamic speed exhibitor. Unlike static speed limit signs, this system would display a recommended speed range based on real-time traffic conditions and weather data. This would be particularly beneficial in Bangladesh, where current static signage proves inadequate during adverse weather conditions.

Automated Street Lighting System:
The project also explores an automated street lighting system. This system would adjust light intensity based on ambient light levels (sunlight) and traffic detection. This would significantly reduce energy waste associated with the current manual system, which often leaves lights on unnecessarily.

Project Plan

In 2018, I reviewed various works related to this topic and discovered separate studies on speed exhibitors and automated street lights. However, none of them provided a unified solution to address traffic jams, road accidents, and energy loss. In this project, I aimed to integrate speed exhibitors and street lights into a single system to tackle all these issues. My project plan includes

Block Diagram of the Main Design

Following the initial project plan development, I constructed a block diagram that mapped out the interconnectivity of the main design components to support the overall project goals.

Circuit Connection of the Main Design

Guided by the block diagram, I assembled the required components on a breadboard, establishing the necessary connections.

Full Mechanism of the Connections

Here, the complete mechanism of the connected components and their roles in fulfilling the project's purpose are presented.

Conclusion

We must ensure that every driver notices the speed range meter in all situations. It should be placed at a sufficient distance from the specific road, allowing both fast and slow drivers ample time to adjust their speed to the required range.

Future Scope

We can also implement this project for foot overbridges and riding lanes to reduce power consumption and accidents
