Navi-Go, developed by Team Llama, addresses urban mobility challenges by offering innovative solutions such as ticket booking, real-time traffic updates, and finding the shortest routes. The team identified language as a barrier and introduced Navi-Go with a conversational language model, enabling multilingual interactions. This facilitates easy access to features like live bus updates, real-time announcements, route exploration, and reporting issues. The system also promotes environmentally friendly practices, encouraging users to adopt sustainable habits for a greener urban mobility experience.

Having real-time updates on transport and urban mobility planners is made easy with real-time notifications by our system in multiple languages, keeping the community informed.

1. For natural language understanding in multiple languages and conversation, we used Gemini, the foundational model of Google, along with GPTs from OpenAI. refer
2. To obtain real-time transit data, we used Google Transit API and the Navigation API. refer
3. Firebase Cloud Messaging and Fast APIs are used to send real-time notifications from the transport department or urban planners to all users.
4. The front end is developed with React, and data, including complaints, is stored in PostgreSQL.
