A web app to explore California transit data with routes, stations, bottlenecks, low-income areas, and an AI chat assistant.

1. Install dependencies:

   pip install -r requirements.txt
   cd app && npm install

2. Add a .env file in the root:

   VITE_GOOGLE_MAPS_API_KEY=your_google_maps_api_key
   VITE_GOOGLE_MAPS_ID=your_map_id
   GEMINI_API_KEY=....
   ask me for it....
   

3. Add data files to app/public/data/ (see below).

Development (live reload):

• In one terminal:
  python app.py
• In another:
  cd app && npm run dev
• Visit: http://localhost:5173

Production:

• Build React:
  cd app && npm run dev
• Start Flask:
  python app.py
• Visit: http://localhost:5173

Place these in app/public/data/:

• routes.json (transit routes)
• bottlenecks.json (traffic bottlenecks)
• low_income.json (low-income areas)
• data.json (stations, optional)

• Interactive Google Map with transit layers
• Filter by route type, state, and mode
• Toggle bottlenecks and low-income areas
• AI Assistant: Ask questions about the map (Gemini-powered)

• Click the 🤖 button to chat about routes, bottlenecks, or transit info.
• Example: "What do the route colors mean?" or "Where are the biggest bottlenecks?"

• California Transit Routes
• Traffic Bottlenecks
• Intermodal Passenger Connectivity
• Low-Income Communities
