This project reimagines how we move goods or people by finding the most "carbon-efficient" routes rather than just the fastest ones. <br> A routing engine that calculates the CO_2 cost of different transit methods based on real-time data. It doesn't just show a map; it provides a "Carbon Budget" for a trip and suggests the optimal time to travel to minimise idle engine time</p> <h2> Demo </h2> <p><a href="https://micro-logistics-optimizer-cspxxpk7pp7dxkzbxqkl8s.streamlit.app/" rel="noopener noreferrer">https://micro-logistics-optimizer-cspxxpk7pp7dxkzbxqkl8s.streamlit.app/</a></p> <h2> Code </h2> <p><a href="https://github.com/hania-faisal/micro-logistics-optimizer/blob/main/app.py" rel="noopener noreferrer">https://github.com/hania-faisal/micro-logistics-optimizer/blob/main/app.py</a></p> <h2> How I Built It </h2> <p>I made it using Google Antigravity. My frontend is made using Streamlit, and the APIs I used inside the project are from Open Route Service. After making it, I pushed it to GitHub and deployed it using Streamlit. </p> <h2> Prize Categories </h2> <p>Best Use of Google Gemini</p> devchallenge weekendchallenge
