IoT Smart Bus Stop

GitHub Repository for Smart Bus Stop

Project Scope

Public transportation is vital to sustainable cities but faces challenges such as unreliable schedules, weather exposure, and limited real-time updates. This project aims to modernise transit infrastructure by integrating IoT, renewable energy, and user-focused design.

The Smart Bus Stop addresses these challenges by:

• Providing real-time information to improve commuter experience.
• Promoting sustainability through solar-powered systems.
• Enhancing user experience with accessible and ergonomic designs.

My Role

As the team leader for this project, I guided a group of four in transforming the vision of an IoT Smart Bus Stop into reality:

• Task Distribution — Assigned responsibilities based on team members’ strengths
• System Development — Led the design and development process, coding most of the system
• Feature Oversight — Oversaw the execution of key IoT and sustainability features
• Collaboration Support — Assisted peers in creating the mock-up, designing the poster, recording/editing the video, and preparing presentation slides

Work Process

Research and Design

• Conducted surveys to understand commuter preferences, revealing that 75% of users prefer real-time transit updates.
• Studied eco-friendly systems to develop solar-powered designs, reducing the carbon footprint.

Prototyping and Development

• Designed the system in Tinkercad for early visualisations.

  

  Tinkercad Design

• Designed bus stop integration using Spline for planning.

  Bus Stop Integration Design

• Integrated BeagleBone Black Wireless for IoT functionalities and cloud integration.
