WeatherRoute is a web-based application that predicts weather conditions along a travel route and offers real-time adjustments. Users input starting and ending points, and the application provides weather forecasts for each segment of their journey, along with the total estimated travel time and total distance.

• Route Navigation: Fetch cities along a route based on origin and destination.
• City Filtering: Filter cities by population.
• Ordered Results: Return cities in the order they appear along the route.
• Weather Forecasting: Predict weather conditions along the route.
• Total Distance Calculation: Calculate and display the total distance of the route in miles.
• Total Travel Time Calculation: Calculate and display the total travel time based on the estimated duration from Google Maps API.

Primary Audience: Travelers and commuters who need to plan trips based on dynamic weather conditions.

Problem Solved: WeatherRoute helps users navigate safely by providing accurate, location-based forecasts and rerouting options to avoid severe weather, improving travel safety and efficiency.

To run this project, you need to have Python 3.x installed. You also need to install the following dependencies:

• Flask
• googlemaps
• polyline
• requests

You can install the required packages using pip:

pip install -r requirements.txt

Before running the application, set your Google Maps API key in the config/settings.py file or as an environment variable:

GOOGLE_MAPS_API_KEY = 'YOUR_API_KEY'

To start the API, run the following command:

python main.py

The application will be available at http://127.0.0.1:5000/create_route and takes in query parameters as input.

To get cities along a route, make a GET request to the /create_route endpoint with origin and destination as query parameters:

curl -X POST http://127.0.0.1:5000/create_route \
-H "Content-Type: application/json" \
-d '{"origin": "Chicago,IL", "destination": "Houston,TX"}'
